In an embodiment, the first processor 103 may compile the code with instructions executable by the second processor 105.

After the code is compiled by the first processor 103, the first processor 103 may transmit to the second processor 105, one or more commands for the compiled code (e.g., a shader including one or more instructions executable by the second processor 105) to be executed in one or more pipelines of the second processor 105. The one or more commands may comprise, for example, at least one of a command to use the compiled code of one or more pipelines of the second processor 105, a command to initialize a portion (e.g., buffer and/or binary cache) of memory 107 to be used in the process of executing the compiled code of one or more pipelines, a command for obtaining one or more command that are running on the one or more pipelines and are executable by the second processor 105, a command to store one or more instructions acquired above in memory, a command for inputting one or more instructions stored in memory with the one or more pipelines, a command for inputting data into one or more pipelines, or a command for executing compiled code based on input data. The second processor 105 may execute a shader related to the compiled code based on the one or more commands. As the shader is executed, the second processor 105 may generate a computer graphic preset by a code.

A series of operations in which the first processor 103 generates instructions executable by the second processor 105 and instructs the instruction generated by the second processor 105 to be executed may be performed in a state in which the first processor 103 executes a game application. For example, in order to create and/or modify a virtual space such as a stage in a game or to generate a video played under a specified condition such as cut-scene and/or event scene, the first processor 103 may perform the operation. The first processor 103 may compile the code stored in the memory 107 to obtain instructions executable by the second processor 105. In the state of compiling the code, the first processor 103 may display a preset UI on the display 109 to induce a standby of the user, such as a loading screen, until completion of the compiling of the code is identified.

The electronic device 101 according to an embodiment may store the code compiled by the first processor 103, for example, one or more instructions executable by the second processor 105, in the memory 107. The electronic device 101 may store cache data including one or more instructions executable by the second processor 105 in the memory 107. In the cache data, information to be input to one or more pipelines of the second processor 105 controlled based on the one or more instructions may be further stored together with the one or more instructions. Information comprised in the cache data will be described in detail with reference to FIG. 4. In an embodiment, the electronic device 101 may be used by a game application and may disperse all instructions executable by the second processor 105 to a plurality of blocks of cache data. For example, the electronic device 101 may generate cache data comprising a portion of instructions executable by the second processor 105. Cache data stored in the electronic device 101 will be described in detail with reference to FIG. 5.

When the pipeline of the second processor 105 is controlled again based on the code after storing the one or more instructions and/or cache data in the memory 107, the first processor 103 may bypass an operation of compiling the code in the first processor 103 based on cache data stored in the memory 107. By bypassing the operation of compiling the code, the first processor 103 may reduce a time for displaying a preset UI inducing a user's standby on the display 109.

The electronic device 120 according to an embodiment may comprise a database for managing cache data generated by the electronic device 101. In an embodiment in which the electronic device 120 comprises a server of a service provider, the electronic device 120 may obtain cache data from an external electronic device owned by each of a plurality of users, such as the electronic device 101. The acquired cache data may be stored in the database together with information of the external electronic device that generated the cache data. The cache data stored in the electronic device 120 may be provided to another external electronic device distinct from the external electronic device providing the cache data and may be used for bypassing compiling of other external electronic devices. An operation in which the electronic device 120 and the electronic device 101 exchange cache data will be described in detail with reference to FIGS. 2 to 3 and 5 to 8. Exchange of cache data may enable partial exchange of shaders related to game applications as instructions executable by the second processor 105 are partially stored in cache data.

For example, the cache data may be a set of information that may be input to the second processor independently from compiling. For example, the cache data may be a set of information that is able to initialize a shader in the second processor without compiling, including a compiled instruction. The information will be described in detail with reference to FIG. 4. The operation of identifying the cache data by the electronic device 101 may comprise information describing the cache data, for example, the operation of identifying metadata corresponding to cache data.

The cache data transmitted by the electronic device 101 to the electronic device 120 may be cache data not stored in the memory (e.g., the memory 124) of the electronic device 120 or cache data having an updated version than the cache data stored in the memory of the electronic device 120. The electronic device 120 according to an embodiment may obtain cache data from electronic devices of subscribers of a game service comprising the electronic device 101 by using a signal indicating upload. The electronic device 120 may maintain the cache data of the entire electronic devices of subscribers of the game service in the latest state by using the obtained cache data.

Since the cache data comprises instructions executable in the second processor, that is, instructions compiled, the electronic device 101 may execute a shader corresponding to the cache data faster based on the cache data. As the shader corresponding to the cache data is rapidly executed, compiling in the first processor may be bypassed in a state of executing the game application. As the compiling of the first processor is bypassed, the electronic device 101 may reduce a time for displaying a preset UI inducing the user's waiting, such as a loading screen.

FIG. 3 is a flowchart of an electronic device according to an embodiment. The electronic device of FIG. 3 may comprise the electronic device 101 of FIGS. 1 and/or 2. For example, at least one of the operations of FIG. 3 may be performed by the electronic device 101 and/or the first processor 103 of FIG. 1. At least one of the operations of FIG. 3 may be related to at least one of the operations of FIG. 2.

Referring to FIG. 3, in operation 310, the electronic device according to an embodiment may identify a plurality of sets of instructions executable by the second processor. The electronic device according to an embodiment may perform operation 310 similar to operation 210 of FIG. 2. The electronic device according to an embodiment may identify instructions stored in the memory of the electronic device and executable by a second processor distinct from the first processor by using a first processor such as a CPU. The second processor may be a processor capable of processing instruction of a type different from that of the first processor, such as a GPU.

The electronic device according to an embodiment may identify multiple sets of instructions for displaying a screen on the display, which may be executed by the second processor among the first processor and the second processor using the first processor. Each of the plurality of sets may comprise at least one of instructions corresponding to one or more shaders included in the pipeline of the second processor or information input to the shader when executed by the second processor. Instructions comprised in the set and executable by the second processor are instructions compiled by the first processor before generating the set and may cause shader execution within the second processor by bypassing the compiling.

The set of instructions executable by the second processor may be referred to hereinafter as cache data and blocks. For example, the electronic device may identify instructions executable by the second processor in memory, within a block corresponding to one of the different states of the game service provided based on at least one or more programs. The block may further comprise information input to the pipeline of the second processor corresponding to the instructions when the instructions comprised in the block are executed by the second processor. For example, the block may comprise one or more instructions to be input to the second processor for execution of the shader and information necessary for execution of the instructions.

Referring to FIG. 3, in operation 320, the electronic device according to an embodiment may transmit metadata corresponding to each of a plurality of sets to an external electronic device. In response to identification of a plurality of sets in operation 310, the electronic device according to an embodiment may transmit metadata corresponding to each of the plurality of sets to an external electronic device (e.g., the electronic device 120 of FIGS. 1 to 2) using a communication circuit. The electronic device according to an embodiment may transmit at least a portion of metadata to an external electronic device.

Metadata transmitted by the electronic device to an external electronic device according to an embodiment may comprise information related to instructions included in each of a plurality of sets. For example, the information may comprise at least one of the size of instructions, the time at which instructions are compiled to be executable by the second processor of the electronic device, the identifier of content corresponding to instructions, or the frequency at which instructions are used by the second processor. Metadata transmitted by an electronic device to an external electronic device according to an embodiment may comprise information for indicating at least one of a set size corresponding to metadata among a plurality of sets or a version related to a screen to be displayed on the display when the set corresponding to metadata is executed by a second processor. The metadata may comprise at least one of an identifier of content corresponding to instructions related to metadata or a frequency at which instructions related to metadata are used by a second processor. For example, at least one of the identifier or the frequency of the content may be encoded in a hash value of metadata.

After transmitting at least, a part of the metadata to the external electronic device based on operation 320, the electronic device may receive a signal related to instructions executable by the second processor from the external electronic device. For example, the electronic device may receive a signal for exchanging a plurality of sets of instructions executable by a second processor between the electronic device and the external electronic device from an external electronic device. The signal may comprise the signal of operation 240 of FIG. 2. At least one of the operations 330, 335, 340, 345, 350, and 355 of FIG. 3 may be performed by an electronic device in response to reception of the signal from an external electronic device.

Referring to FIG. 3, in operation 330, the electronic device according to an embodiment may determine whether one or more sets distinct from the identified sets are received from an external electronic device. For example, the external electronic device may transmit a signal comprising a command for adding one or more sets of instructions executable by the second processor to the electronic device. The signal may comprise one or more sets distinct from the sets identified in the electronic device based on operation 310.

In response to receiving one or more sets distinct from the identified sets from the external electronic device (330-yes), in operation 335, the electronic device according to an embodiment may merge and store a plurality of identified sets and the received sets. After transmitting metadata based on operation 320, The electronic device according to an embodiment may download a set distinct from a plurality of sets identified in operation 310 as a set of instructions executable by the second processor of the electronic device using the first processor of the electronic device based on a signal received from the external electronic device. From a signal received from an external electronic device, the other instructions may be stored in the memory in response to identification of other instructions that may be executed by a second processor and distinct from a plurality of instructions stored in the electronic device. For example, the electronic device may merge and store the other instructions with a plurality of instructions stored in the electronic device.

The set of instructions that the electronic device receives from the external electronic device according to an embodiment is a set independent of a plurality of sets of instructions stored in the electronic device, for example, may include instructions that are relatively less used than the plurality of sets. The set of instructions that the electronic device receives from the external electronic device is a set corresponding to a state distinct from a state of an application corresponding to each of a plurality of sets stored in the electronic device, for example, may be a set corresponding to a state in which an application is expected to enter.

Referring to FIG. 3, in operation 340, the electronic device according to an embodiment may determine whether a set corresponding to at least one of a plurality of sets is received from an external electronic device. For example, the external electronic device may transmit a signal comprising a command for updating a set of instructions executable by the second processor to the electronic device. The signal may comprise a set in which at least one of the sets identified in the electronic device is updated based on operation 310.

In response to receiving a set corresponding to at least one of a plurality of sets from an external electronic device (340-Yes), in operation 345, the electronic device according to an embodiment may modify at least one of the plurality of identified sets based on the received set. In response to identification of instructions executable by a second processor within a signal received from an external electronic device, the electronic device according to an embodiment may replace instructions stored in memory based on the identified instructions. In response to identification of a command for updating instructions stored in the electronic device from a signal received from the external electronic device, the electronic device according to an embodiment may replace instructions stored in the electronic device based on instructions comprised in the signal.

The set of instructions received by the electronic device from an external electronic device may further include information necessary to execute the instruction-based shader included in the set on the second processor. The size of the set of instructions received by the electronic device from an external electronic device may correspond to the set and may be larger than the size of the set stored in the electronic device. The version of the set of instructions received by the electronic device from an external electronic device may correspond to the set and have a later version than the version of the set stored in the electronic device.

The electronic device according to an embodiment may determine whether to modify the set stored in the electronic device by using the size and/or version of the received instruction set. For example, when the size of the set of instructions received by the electronic device is larger than the size of the set stored in the electronic device, the electronic device may modify the set stored in the electronic device based on the set of instructions received. For example, when the version of the set of instructions received by the electronic device is a later version than the version of the set stored in the electronic device, the electronic device may modify the set stored in the electronic device based on the set of instructions received.

Referring to FIG. 3, in operation 350, the electronic device according to an embodiment may determine whether a command for uploading at least one of the identified sets is received from an external electronic device. For example, an external electronic device may send a command to upload at least one set to the electronic device in response to identification of a set having a later version than a set stored in an external electronic device or a set having a larger size than a set stored in an external electronic device, among a plurality of sets of instructions stored in the electronic device.

When a command for uploading at least one of the identified sets is received from an external electronic device (350-Yes), in operation 355, the electronic device according to an embodiment may upload one or more sets corresponding to the command among a plurality of identified sets. After transmitting the metadata of operation 320, the electronic device according to an embodiment may upload at least one of a plurality of sets to the external electronic device using a first processor based on a signal received from the external electronic device. The set of instructions uploaded by the electronic device to the external electronic device may be a set corresponding to a command received from the external electronic device. From a signal received from an external electronic device, the electronic device may transmit instructions executable by the second processor to the external electronic device in response to identification of a command indicating upload of instructions executable by the second processor.

At least one of the operations described in FIG. 3 may be performed based on any one of a plurality of threads generated by a preset application (e.g., a game application) executed by the first processor of the electronic device. For example, the electronic device according to an embodiment may perform at least one of the operations of FIG. 3 by using another thread distinct from the main thread of the game application. For example, the operation of the electronic device uploading a set of instructions executable by the second processor to the external electronic device based on the operation 355 may be performed based on another thread that is running in the first processor and is distinct from the main thread of the game application.

Based on FIG. 3, the electronic device and the external electronic device may complete the exchange of a set of instructions executable by the second processor. The electronic device according to an embodiment may execute a shader related to an application running in the electronic device using at least one of the sets of exchanged instructions. For example, in response to entering a preset state corresponding to instructions stored in a memory and executable by a second processor among a plurality of states of a game service provided at least based on one or more programs, the first processor of the electronic device according to an embodiment may transmit a signal indicating execution of a pipeline (or shader) based on the instructions to the second processor while transmitting a set of instructions stored in the memory. The entering into the preset state may be performed in response to a call of an API for compiling the instructions stored in a memory by the first processor of the electronic device. For example, the first processor of the electronic device may transmit a set of instructions stored in the memory to the second processor in a state of bypassing the compiling despite the call of the API for compiling the instructions.

In a state of using the set of instructions stored in the memory by the second processor, the electronic device may modify information related to the number of executions of the pipeline based on the set of instructions in the memory. For example, the electronic device may modify a parameter such as the frequency of use of cache data stored in the hash value of Table 1. The frequency of use may determine a state in which an application running in the electronic device is expected to enter and may cause download of cache data corresponding to a state predicted from an external electronic device. Since the download of cache data corresponding to the predicted state is performed in advance, the electronic device may bypass compiling by the first processor and input the downloaded cache data to the second processor in response to entering the predicted state. While inputting the downloaded cache data to the second processor, the electronic device may request execution of a shader based on the input cache data. By bypassing compiling, the time spent on executing the shader may be reduced.

FIG. 4 is an exemplary diagram for describing cache data 410 stored in a memory by an electronic device according to an embodiment. The electronic device of FIG. 4 may comprise the electronic device 101 of FIGS. 1 and/or 2. The memory of FIG. 4 may comprise the memory 107 of FIG. 1.

Referring to FIG. 4, the cache data 410 stored in the electronic device may comprise instructions executable by the second processor (e.g., the second processor 105 of FIG. 1) of the electronic device and may comprise a pipeline 420 to be input from the second processor. The pipeline 420 may mean a shader to be executed using the graphics pipeline of the second processor. The pipeline 420 is instructions executable by the second processor and may comprise instructions compiled before the cache data 410 is stored in memory.

The electronic device according to an embodiment may further store information related to the pipeline 420 in the cache data 410. The electronic device according to an embodiment may store information necessary for generating (i.e., rendering) frame data through execution of the shader in the cache data 410. For example, the electronic device may store pipeline layout information 415 indicating the layout of the pipeline 420 together with instructions executable by the second processor in the cache data 410. The pipeline layout information 415 may represent a combination of one or more operations related to execution of the pipeline 420 among a plurality of operations supported by the graphic pipeline of the second processor.

For example, the electronic device may store dynamic state information 440 of the pipeline 420 together with instructions executable by the second processor in the cache data 410. The dynamic state information 440 may comprise information necessary for changing the state of the shader without changing or re-inputting the shader being executed in the graphic pipeline. The dynamic state information 440 may comprise at least one of a view port, a scissor test, a blending constant, a stencil reference, a depth bound, or a depth bias.

The electronic device according to an embodiment may store information to be input to the second processor in a state in which the pipeline 420 is executed in the second processor in the cache data 410. The information to be input to the second processor may comprise, for example, information to be processed by the shader, such as material or renderer state. Referring to FIG. 4, as information to be input to the second processor, the electronic device may store at least one of the shader module 422, the shader stage 424, the vertex data 426, the tessellation data 428, the viewport data 430, or the rasterization data 432 in the cache data 410. Shader module 422 may mean a set of instructions executable by the second processor. The shader stage 424 may mean a set of instructions that are executable by the second processor and are independent of the platform, such as spir-V. The vertex data 426 may comprise information input to the shader and related to a point based on 3D coordinates. For example, the vertex data 426 may comprise a vertex input description. For example, the vertex data 426 may comprise parameters indicating a state of the vertex, such as information for binding the vertex to the pipeline, a format of the vertex, a vertex stride, and an input rate. The tessellation data 428 may comprise information for dividing a plane having a point based on three-dimensional coordinates as a vertex. The viewport data 430 is an area to be output to a display (e.g., display 109) of an electronic device, and may comprise information indicating an area viewable by at least a part of the display among spaces based on the three-dimensional coordinates. The rasterization data 432 may comprise information for generating a two-dimensional image in which a space based on three-dimensional coordinates is projected.

Materials such as vertex data 426, tessellation data 428, viewport data 430, and rasterization data 432 may correspond to information input to the shader while the shader based on the pipeline 420 is executed in the second processor. As the cache data 410 comprises both a shader to be executed in the second processor and information to be input to the shader, after being input to the second processor, the cache data 410 may be executed immediately after being input to the second processor by bypassing the compiling by the first processor. After the cache data 410 is input by the second processor, the second processor may generate frame data to be output through the display without requiring additional data input. As the cache data 410 comprises both a shader to be executed in the second processor and information to be input to the shader, the electronic device according to an embodiment may reduce a time delay occurring while generating the shader and inputting the information to the shader.

The electronic device according to an embodiment may manage cache data 410 stored in the memory 107 based on a block. A single block stored in the electronic device may correspond to any one of a plurality of states preset by a preset application such as a game application. In an embodiment, the state may correspond to a part of a virtual space defined by a game application. For example, when a character of a user using a game application enters a part of the virtual space, the electronic device according to an embodiment may perform rendering of the virtual space using the cache data 410. For example, the first processor of the electronic device may store blocks of cache data 410 corresponding to each of the different parts of the virtual space in memory 107, and in response to switching between the parts by a user using a game application, the second processor of the electronic device may selectively fetch any one of the blocks of cache data 410 from the memory 107.

In an embodiment, a state corresponding to each of the blocks of the cache data 410 stored in the memory 107 may correspond to a video played by a game application. For example, when the electronic device reproduces a video comprising a plurality of cut-scene based on a game application, each of the blocks of the cache data 410 may correspond to each of the plurality of cut-scenes. In a state of sequentially reproducing a plurality of cut-scenes, the electronic device may fetch blocks of the cache data 410 from the memory 107 based on the order of the cut-scenes being reproduced.

As the electronic device according to various embodiments manages the cache data 410 based on the plurality of blocks, while efficiently using the network by selectively updating a plurality of blocks, the electronic device may reduce a delay generated by downloading and/or generating cache data 410. Hereinafter, an operation in which the electronic device manages the cache data 410 based on a plurality of blocks will be described in detail with reference to FIG. 5.

FIG. 5 is an exemplary diagram illustrating an operation of exchanging cache data by a plurality of electronic devices according to an embodiment. The cache data of FIG. 5 may comprise the cache data 410 of FIG. 4. The operation of exchanging the cache data of FIG. 5 may be related to at least one of the operations of FIGS. 2 to 3.

Referring to FIG. 5, blocks of cache data stored in the memory 510 of the first electronic device are illustrated. Referring to FIG. 5, blocks of cache data stored in the memory 550 of the second electronic device are illustrated. Each of the first electronic device and the second electronic device of FIG. 5 may correspond to the electronic device 101 and the electronic device 120 of FIG. 1. Each of the blocks of cache data may be distributed within the memories 510 and 550 by applying a hash function to a hash value of a shader corresponding to a game application. The first electronic device according to an embodiment may execute an application corresponding to the cache data in a state in which it does not have all blocks of the cache data. In the example of FIG. 5, the first electronic device may execute an application in a state in which only the first block 512, the third block 516, and the fourth block 518 are stored in the memory 510 among the first to fourth blocks of cache data.

The first electronic device to the second electronic device may perform at least one of the operations described in FIGS. 2 to 3. The first electronic device according to an embodiment may transmit metadata for each of the first block 512, the third block 516, and the fourth block 518 of cache data stored in the memory 510 to the second electronic device. For example, the metadata may comprise information for describing each of the first block 512, the third block 516, and the fourth block 518 based on at least one of the parameters in Table 1.

In response to receiving metadata for each of the first block 512, the third block 516, and the fourth block 518, the second electronic device may compare cache data stored in the first electronic device with cache data stored in the second electronic device. Comparison of cache data may be performed independently in each of the blocks of cache data. In the example of FIG. 5, the second electronic device may store only the first block 552, the second block 554, and the fourth block 558 among the first to fourth blocks of cache data in the memory 550. The second electronic device may compare blocks of cache data stored in the memory 550 and blocks of cache data stored in the memory 510 of the first electronic device identified by metadata, respectively.

As the comparison of cache data is performed independently in each of the blocks of cache data, the exchange of cache data between the first electronic device and the second electronic device may be performed independently in each of the blocks of cache data. For example, when the first block 512 of cache data stored in the first electronic device and the first block 552 of cache data stored in the second electronic device are identical to each other, exchange of the first blocks 512 and 552 of cache data between the first electronic device and the second electronic device may not be performed. Independently of the exchange of the first blocks 512 and 552 is not performed, the second electronic device may perform exchanging other blocks of cache data. For example, when the second block 554 of cache data stored in the memory 550 of the second electronic device is not stored in the first electronic device, the second electronic device may transmit a command indicating the download of the second block 554 to the first electronic device. The command may be transmitted to the first electronic device together with the second block 554.

In the example of FIG. 5, a second block 554 of cache data that causes the first electronic device to download is a block selected by the second electronic device according to an embodiment and may be a block that is most likely to be executed by the second processor (e.g., the second processor 105 of FIG. 1) of the first electronic device among blocks not stored in the first electronic device. For example, the second electronic device may select a block to be transmitted to the first electronic device based on the frequency of use, priority, and/or order of use of each of the blocks of cache data. For example, in a state in which the first electronic device storing only the first block 512, the third block 516, and the fourth block 518 of cache data is identified, the second electronic device may transmit a block having a higher frequency of use than the first block 512, the third block 516, and/or the fourth block 518, or a block executed adjacent to the first block 512, the third block 516, and/or the fourth block 518 to the first electronic device.

When the first electronic device identifies a block of cache data not stored in the memory 550 of the second electronic device, the second electronic device may transmit a command indicating uploading of the identified block to the first electronic device. In the example of FIG. 5, the second electronic device may identify a third block 516 of cache data not stored in the memory 550 based on metadata received from the first electronic device. In response to identification of the third block 516 not stored in the memory 550, the second electronic device may transmit a command indicating uploading of the third block 516 to the first electronic device. In response to receiving the command indicating the upload, the first electronic device may transmit the third block 516 to the second electronic device. The second electronic device may store the received third block 516 in combination with other blocks (e.g., the first block 552, the second block 554, and the fourth block 558) of cache data stored in the memory 550. The second electronic device may transmit the stored third block 516 to another electronic device distinct from the first electronic device.

The exchange of blocks of cache data between the first electronic device and the second electronic device may cause selective updates in the blocks. For example, the second electronic device may identify the version and/or size of each of the first block 512, the third block 516, and the fourth block 518 stored in the first electronic device based on metadata received from the first electronic device. The identified version and/or size may be used to compare blocks of cache data stored in each of the first electronic device and the second electronic device.

For example, when the size of the fourth block 518 stored in the first electronic device is smaller than the size of the fourth block 558 stored in the second electronic device, the second electronic device may transmit a command indicating the update of the fourth block 518 to the first electronic device. For example, when the version of the fourth block 518 stored in the first electronic device is the previous version of the version of the fourth block 558 stored in the second electronic device, the second electronic device may transmit a command indicating the update of the fourth block 518 to the first electronic device. The command may be transmitted to the first electronic device together with the fourth block 558.

In response to receiving a command indicating the update of the fourth block 518 from the second electronic device, the first electronic device according to an embodiment may update the fourth block 518 stored in the first electronic device using the fourth block 558 of cache data stored in the second electronic device. For example, the first electronic device may remove the fourth block 518 from the memory 510 and store the fourth block 558 obtained from the second electronic device in the memory 510. For example, the first electronic device may overwrite the fourth block 558 obtained from the second electronic device in a part where the fourth block 518 is stored in the memory 510.

After performing the exchange of the block of cache data based on the communication connection established with the second electronic device, the first electronic device may control a pipeline of the second processor based on a block of cache data stored in the memory 510. Hereinafter, an operation in which the first electronic device controls the pipeline of the second processor will be described in detail with reference to FIG. 6.

FIG. 6 is a flowchart illustrating an operation performed by an electronic device to control a pipeline of a second processor according to an embodiment. The electronic device of FIG. 6 may comprise the electronic device 101 of FIGS. 1 to 2. At least one of the operations of FIG. 6 may be performed by the first processor 103 of FIG. 1.

Referring to FIG. 6, in operation 610, the electronic device according to an embodiment may execute one or more instructions comprised in an application using a first processor. The application may correspond to a preset application for providing a game service. The electronic device according to an embodiment may perform operation 610 in response to a user input for executing an application. For example, by executing one or more instructions related to an application and executable in the first processor from a memory (e.g., the memory 107 of FIG. 1), the electronic device may perform operation 610.

In a state of executing one or more instructions included in an application using the first processor, in operation 620, the electronic device according to an embodiment may identify instructions executing a pipeline (e.g., pipeline 420 of FIG. 4) using the second processor. The pipeline may be related to a second processor graphic pipeline and/or shader. The pipeline using the second processor may represent, for example, a series of operations for generating frame data to be output to the display (e.g., the display 109 of FIG. 1) of the electronic device.

The electronic device according to an embodiment may perform operation 620 in response to a preset event and/or entry into a state in a state in which the application is executed using the first processor based on operation 610. For example, the first processor may identify an instruction executing a pipeline using the second processor based on an API for generating an instruction executable by the second processor. The API is an instruction executable on the first processor, and may comprise, for example, an instruction causing compiling of the code by the first processor.

Until an instruction executing the pipeline using the second processor is identified (620-No), the electronic device according to an embodiment may maintain execution of one or more instructions on the first processor based on operation 610. In response to identification of an instruction executing a pipeline using the second processor (620-Yes), in operation 630, the electronic device according to an embodiment may determine whether cache data (e.g., cache data 410 of FIG. 4) corresponding to the pipeline exists in the memory. The electronic device according to an embodiment may search for cache data comprising instructions executable in the second processor in the memory based on operation 210 of FIG. 2 and/or operation 310 of FIG. 3. The cache data may be stored in the electronic device as shown in the example of FIG. 5.

The electronic device according to an embodiment may perform an operation of identifying cache data based on operation 630 using a thread independently executed from operations 610 and 620. For example, the electronic device may execute one or more instructions executable in the first processor based on operation 610 in the first thread such as the main thread executed in the first processor. In response to identifying instructions for executing a pipeline using a second processor by performing operation 620 using a first thread, the electronic device is executed in the first processor, and may perform operation 630 using a second thread distinct from the first thread. The electronic device may execute operation 630 independently of the first thread and time using the second thread. In a state in which the electronic device performs the operation 630 using the second thread, the electronic device may maintain performing the operations 610 and 620 using the first thread.

When cache data corresponding to the pipeline exists (630-Yes), in operation 640, the electronic device according to an embodiment may transmit metadata corresponding to the cache data to an external electronic device. For example, the electronic device may perform operation 640 based on operation 220 of FIG. 2 and/or operation 320 of FIG. 3. Metadata transmitted by the electronic device to an external electronic device may include at least one of the parameters in Table 1. In an embodiment in which the electronic device stores cache data based on a plurality of blocks, the electronic device may transmit metadata for each of the plurality of blocks to an external electronic device. The metadata may include at least one of information for identifying a pipeline corresponding to the cache data and/or a frequency of use of the pipeline.

The external electronic device (e.g., the electronic device 120 of FIGS. 1 to 2) that has received metadata corresponding to the cache data may identify a pipeline stored in the electronic device based on the received metadata. The external electronic device may transmit a signal related to a change of cache data stored in the electronic device by performing at least one of operations 230 and 240 of FIG. 2. For example, when the cache data stored in the external electronic device is the updated cache data of the cache data stored in the electronic device, the external electronic device may transmit a signal related to the change of the cache data to the electronic device. The signal transmitted by the external electronic device to the electronic device may comprise cache data stored in the external electronic device together with a command indicating a change in cache data. In an embodiment in which the electronic device stores cache data based on a plurality of blocks, the signal transmitted by the external electronic device to the electronic device may comprise a command to modify at least one of the blocks of the cache data.

After transmitting metadata corresponding to the cache data, in operation 650, the electronic device according to an embodiment may determine whether a signal for changing the cache data has been received from an external electronic device. The signal for changing the cache data may include a signal corresponding to a command related to updating the cache data.

When a signal for changing the cache data is received (650-Yes), in operation 660, the electronic device according to an embodiment may modify the cache data based on the received signal. For example, the electronic device may modify the cache data in the memory identified in operation 630 based on the cache data comprised in the received signal. The cache data comprised in the signal received by the electronic device from the external electronic device according to an embodiment may have a larger size than the cache data in the memory identified in operation 630. The cache data comprised in the signal received by the electronic device from an external electronic device according to an embodiment may have a later version than the cache data in the memory identified in operation 630. In an embodiment in which the electronic device stores cache data based on a plurality of blocks, the electronic device may modify at least one of blocks of cache data stored in the electronic device based on the received signal. The block of cache data changed by the electronic device may include one or more instructions for executing the pipeline identified in operation 620.

After not receiving a signal for changing the cache data (660-No), and/or changing the cache data based on operation 660, in operation 670, the electronic device according to an embodiment may control the second processor based on the cache data. The electronic device according to an embodiment may bypass the compiling of a code corresponding to the pipeline of operation 620 as a compiling performed by the first processor. The electronic device may input cache data identified in operation 630 and/or cache data changed by operation 660 to the second processor while bypassing the compiling.

The electronic device may cause execution of the pipeline of operation 620 in the second processor based on the input cache data. For example, the electronic device may initialize a shader using the graphic pipeline of the second processor based on one or more instructions comprised in the cache data. The electronic device may acquire frame data from the shader by inputting information comprising cache data to the initialized shader. In response to the acquisition of the frame data, the electronic device may output a screen corresponding to the frame data acquired on the display.

When cache data corresponding to the pipeline does not exist (630-No), in operation 680, the electronic device according to an embodiment may obtain instruction executable on the second processor. For example, the electronic device may obtain one or more instructions executable on the second processor from code encoded in the shader language using a driver program corresponding to the second processor being executed on the first processor. One or more instructions executable on the second processor among the first processor and the second processor may be generated by the compiling performed on the first processor.

In response to the acquisition of an instruction executable in the second processor, in operation 685, the electronic device according to an embodiment may control the second processor based on the obtained instruction. Controlling the second processor based on the instructions obtained by the electronic device may be performed similarly to controlling the second processor based on the instructions included in the cache data in operation 670. In an embodiment, when the cache data corresponding to the pipeline is not stored in the memory, the electronic device may stop bypassing the compiling in the first processor and perform the compiling in the first processor. The electronic device may obtain frame data to be output to the display by controlling the graphic pipeline in the second processor based on the compiled instruction.

Referring to FIG. 6, in operation 690, the electronic device according to an embodiment may store cache data corresponding to the obtained instruction. For example, in a state in which operation 685 is performed, the electronic device may generate one or more blocks of cache data by combining one or more instructions input to the second processor and information input to a shader executed by the one or more instructions. The electronic device may store the generated one or more blocks of cache data in a memory.

The electronic device may store metadata corresponding to the generated one or more blocks of cache data in a memory. The metadata may have an initialized frequency of use. After operation 690, whenever a block of cache data stored by operation 690 is called, the frequency of use of metadata corresponding to the called block may be gradually increased. The block of cache data stored by operation 690, after operation 690, may be identified by an external electronic device as at least one of operation 640, operation 320 of FIG. 3, or operation 220 of FIG. 2 is performed again by the electronic device. When the block of cache data stored in operation 690 has an updated version than the block of cache data stored in the external electronic device, the external electronic device may transmit a signal requesting upload of the block of cache data to the electronic device.

Referring to FIG. 7, in operation 730, the electronic device according to an embodiment may determine whether the external electronic device requires another set distinct from the set corresponding to the received metadata. For example, based on sets of instructions identified from an external electronic device based on metadata, the electronic device may identify the set with the highest executability among the sets different from the above sets in the external electronic device. When the set comprises the cache data 410 of FIG. 4, the electronic device may determine whether the external electronic device requires another set based on the hit rate and/or priority of the cache data.

When the external electronic device requires the other set (730-Yes), in operation 735, the electronic device according to an embodiment may transmit a signal for storing the other set to the external electronic device. The signal may comprise a command for instructing download of the other set by an external electronic device. The external electronic device receiving the signal may store another set comprised in the received signal, for example, based on operation 335 of FIG. 3.

When the external electronic device requires to modify the set (740-Yes), in operation 745, the electronic device according to an embodiment may transmit a signal for changing the set corresponding to the received metadata to the external electronic device. The signal may comprise a command for instructing an update of a set by an external electronic device. The external electronic device receiving the signal may update a set stored in the external electronic device, for example, based on operation 345 of FIG. 3.

Referring to FIG. 7, in operation 750, the electronic device according to an embodiment may determine whether a set corresponding to the received metadata is required to be uploaded. The electronic device according to an embodiment may identify a set not stored in the electronic device and/or a set having a later version than a set stored in the electronic device, among sets of external electronic devices recognized by metadata.

When uploading a set is required (750-Yes), in operation 752, the electronic device according to an embodiment may transmit a signal for uploading a set corresponding to the received metadata to the external electronic device. The signal may include a command indicating uploading of a set by an external electronic device. One or more sets may be transmitted to the electronic device based on the external electronic device receiving the signal, for example, operation 355 of FIG. 3.

After transmitting the signal, in response to receiving one or more sets from an external electronic device, in operation 754, the electronic device according to an embodiment may store a set uploaded in the electronic device.
