20230186799
The present disclosure relates generally to processing systems and, more particularly, to one or more techniques for graphics processing.
Computing devices often perform graphics and/or display processing (e.g., utilizing a graphics processing unit (GPU), a central processing unit (CPU), a display processor, etc.) to render and display visual content. Such computing devices may include, for example, computer workstations, mobile phones such as smartphones, embedded systems, personal computers, tablet computers, and video game consoles. GPUs are configured to execute a graphics processing pipeline that includes one or more processing stages, which operate together to execute graphics processing commands and output a frame. A central processing unit (CPU) may control the operation of the GPU by issuing one or more graphics processing commands to the GPU. Modern day CPUs are typically capable of executing multiple applications concurrently, each of which may need to utilize the GPU during execution. A display processor is configured to convert digital information received from a CPU to analog values and may issue commands to a display panel for displaying the visual content. A device that provides content for visual presentation on a display may utilize a GPU and/or a display processor.
A GPU of a device may be configured to perform the processes in a graphics processing pipeline. Further, a display processor or display processing unit (DPU) may be configured to perform the processes of display processing. However, with the advent of wireless communication and smaller, handheld devices, there has developed an increased need for improved graphics or display processing.
The following presents a simplified summary of one or more aspects in order to provide a basic understanding of such aspects. This summary is not an extensive overview of all contemplated aspects, and is intended to neither identify key or critical elements of all aspects nor delineate the scope of any or all aspects. Its sole purpose is to present some concepts of one or more aspects in a simplified form as a prelude to the more detailed description that is presented later.
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a client device or any apparatus that may perform graphics processing. The apparatus may receive, from a server, a plurality of data packets corresponding to data for each of a plurality of frames associated with at least one application, the data for each of the plurality of frames being monochrome color data or polychrome color data. The apparatus may also convert the plurality of data packets to content associated with the data for each of the plurality of frames, the content including at least one of monochrome color content or a luminance component. Additionally, the apparatus may decrypt the content associated with the data for each of the plurality of frames, where the content is decrypted prior to the color space conversion, the decrypted content including at least one of the monochrome color content or the luminance component. The apparatus may also decode the decrypted content associated with the data for each of the plurality of frames, where the content is decoded prior to the color space conversion, the decoded content including at least one of the monochrome color content or the luminance component. Moreover, the apparatus may perform a color space conversion on the content associated with the data for each of the plurality of frames, the color space conversion adding at least one chrominance plane to the content. The apparatus may also display, upon performing the color space conversion, the content associated with the data for each of the plurality of frames.
In an aspect of the disclosure, a method, a computer-readable medium, and an apparatus are provided. The apparatus may be a server or any apparatus that may perform graphics processing. The apparatus may receive data for each of a plurality of frames associated with at least one application, the data for each of the plurality of frames being monochrome color data or polychrome color data. The apparatus may also render content associated with the data for each of the plurality of frames, the rendered content including at least one of monochrome color content or a luminance component. Also, the apparatus may encode the rendered content associated with the data for each of the plurality of frames, where the rendered content is encoded prior to being converted, the encoded content including at least one of the monochrome color content or the luminance component. The apparatus may also encrypt the encoded content associated with the data for each of the plurality of frames, where the encoded content is encrypted prior to being converted, the encrypted content including at least one of the monochrome color content or the luminance component. Further, the apparatus may convert the rendered content associated with the data for each of the plurality of frames to a plurality of data packets. The apparatus may also transmit, to a client device, the plurality of data packets corresponding to the rendered content associated with the data for each of the plurality of frames.
The details of one or more examples of the disclosure are set forth in the accompanying drawings and the description below. Other features, objects, and advantages of the disclosure will be apparent from the description and drawings, and from the claims.
Some aspects of graphics processing may be associated with rendering or displaying different types of content, e.g., virtual reality (VR) content, extended reality (XR), or augmented reality (AR) content. The content may be rendered or created on a server, e.g., a computer or phone. To display this content, users may utilize different types of headsets or display glasses, which may be referred to as a client device. In some instances, when a user wants to use XR glasses for a long duration in the absence of a charging facility, it is desirable to save power at the server or client device. Also, when the battery of either the client device or the server is getting low (i.e., beyond a threshold percentage decided by the user), it is desirable to save power at the server or client device. Moreover, if a user would like to extend battery life voluntarily, then it is desirable to save power at the server or client device and provide a long battery life to either device. Some solutions for power saving may be associated with reducing a frame resolution rate or utilizing foveated rendering during the rendering/display process in order to reduce power usage and/or improve performance at the server/client device. Additionally, the rendering pipeline (e.g., at a graphics processing unit (GPU)) may utilize full color or chrominance data. If each step in the rendering pipeline is associated with the processing of full color/chrominance data, this may waste a large amount of power. Indeed, by processing full/polychrome color data or full/polychrome chrominance data at every step in a split rendering process, more power may be utilized than may otherwise be necessary. In turn, this may waste a large amount of power at each of the devices, e.g., the server and the client device. Aspects of the present disclosure may process some steps in a split rendering process or a non-split rendering process without using full color data or polychrome color data. For instance, aspects of the present disclosure may allow for the processing of some steps in a split rendering process or a non-split rendering process using monochrome color data. Additionally, in some instances, aspects of the present disclosure may process some steps in a split rendering process or a non-split rendering process using a luminance component, instead of both a luminance component and a chrominance component. By doing so, aspects of the present disclosure may save a large amount of power at each of the devices in a split rendering process (e.g., the server and the client device) or a non-split rendering process. Accordingly, aspects of the present disclosure may reduce the amount of power utilized during color data processing in a split rendering process or a non-split rendering process.

The term application may refer to software. As described herein, one or more techniques may refer to an application, i.e., software, being configured to perform one or more functions. In such examples, the application may be stored on a memory, e.g., on-chip memory of a processor, system memory, or any other memory. Hardware described herein, such as a processor may be configured to execute the application. For example, the application may be described as including code that, when executed by the hardware, causes the hardware to perform one or more techniques described herein. As an example, the hardware may access the code from a memory and execute the code accessed from the memory to perform one or more techniques described herein. In some examples, components are identified in this disclosure. In such examples, the components may be hardware, software, or a combination thereof. The components may be separate components or sub-components of a single component.
Accordingly, in one or more examples described herein, the functions described may be implemented in hardware, software, or any combination thereof If implemented in software, the functions may be stored on or encoded as one or more instructions or code on a computer-readable medium. Computer-readable media includes computer storage media. Storage media may be any available media that may be accessed by a computer. By way of example, and not limitation, such computer-readable media may comprise a random access memory (RAM), a read-only memory (ROM), an electrically erasable programmable ROM (EEPROM), optical disk storage, magnetic disk storage, other magnetic storage devices, combinations of the aforementioned types of computer-readable media, or any other medium that may be used to store computer executable code in the form of instructions or data structures that may be accessed by a computer.
In general, this disclosure describes techniques for having a graphics processing pipeline in a single device or multiple devices, improving the rendering of graphical content, and/or reducing the load of a processing unit, i.e., any processing unit configured to perform one or more techniques described herein, such as a GPU. For example, this disclosure describes techniques for graphics processing in any device that utilizes graphics processing. Other example benefits are described throughout this disclosure.
As used herein, instances of the term “content” may refer to “graphical content,” “image,” and vice versa. This is true regardless of whether the terms are being used as an adjective, noun, or other parts of speech. In some examples, as used herein, the term “graphical content” may refer to a content produced by one or more processes of a graphics processing pipeline. In some examples, as used herein, the term “graphical content” may refer to a content produced by a processing unit configured to perform graphics processing.

In some examples, as used herein, the term “display content” may refer to content generated by a processing unit configured to perform displaying processing. In some examples, as used herein, the term “display content” may refer to content generated by a display processing unit. Graphical content may be processed to become display content. For example, a graphics processing unit may output graphical content, such as a frame, to a buffer (which may be referred to as a framebuffer). A display processing unit may read the graphical content, such as one or more frames from the buffer, and perform one or more display processing techniques thereon to generate display content. For example, a display processing unit may be configured to perform composition on one or more rendered layers to generate a frame. As another example, a display processing unit may be configured to compose, blend, or otherwise combine two or more layers together into a single frame. A display processing unit may be configured to perform scaling, e.g., upscaling or downscaling, on a frame. In some examples, a frame may refer to a layer. In other examples, a frame may refer to two or more layers that have already been blended together to form the frame, i.e., the frame includes two or more layers, and the frame that includes two or more layers may subsequently be blended.
The processing unit 120 may include an internal memory 121. The processing unit 120 may be configured to perform graphics processing, such as in a graphics processing pipeline 107. The content encoder/decoder 122 may include an internal memory 123.

The internal memory 121 or the system memory 124 may be a non-transitory storage medium according to some examples. The term “non-transitory” may indicate that the storage medium is not embodied in a carrier wave or a propagated signal. However, the term “non-transitory” should not be interpreted to mean that internal memory 121 or the system memory 124 is non-movable or that its contents are static. As one example, the system memory 124 may be removed from the device 104 and moved to another device. As another example, the system memory 124 may not be removable from the device 104.

As described herein, a device, such as the device 104, may refer to any device, apparatus, or system configured to perform one or more techniques described herein. For example, a device may be a server, a base station, user equipment, a client device, a station, an access point, a computer, e.g., a personal computer, a desktop computer, a laptop computer, a tablet computer, a computer workstation, or a mainframe computer, an end product, an apparatus, a phone, a smart phone, a server, a video game platform or console, a handheld device, e.g., a portable video game device or a personal digital assistant (PDA), a wearable computing device, e.g., a smart watch, an augmented reality device, or a virtual reality device, a non-wearable device, a display or display device, a television, a television set-top box, an intermediate network device, a digital media player, a video streaming device, a content streaming device, an in-car computer, any mobile device, any device configured to generate graphical content, or any device configured to perform one or more techniques described herein. Processes herein may be described as performed by a particular component (e.g., a GPU), but, in further embodiments, may be performed using other components (e.g., a CPU), consistent with disclosed embodiments.
GPUs may process multiple types of data or data packets in a GPU pipeline. For instance, in some aspects, a GPU may process two types of data or data packets, e.g., context register packets and draw call data. A context register packet may be a set of global state information, e.g., information regarding a global register, shading program, or constant data, which may regulate how a graphics context will be processed. For example, context register packets may include information regarding a color format. In some aspects of context register packets, there may be a bit that indicates which workload belongs to a context register. Also, there may be multiple functions or programming running at the same time and/or in parallel. For example, functions or programming may describe a certain operation, e.g., the color mode or color format. Accordingly, a context register may define multiple states of a GPU.
Context states may be utilized to determine how an individual processing unit functions, e.g., a vertex fetcher (VFD), a vertex shader (VS), a shader processor, or a geometry processor, and/or in what mode the processing unit functions. In order to do so, GPUs may use context registers and programming data. In some aspects, a GPU may generate a workload, e.g., a vertex or pixel workload, in the pipeline based on the context register definition of a mode or state. Certain processing units, e.g., a VFD, may use these states to determine certain functions, e.g., how a vertex is assembled. As these modes or states may change, GPUs may need to change the corresponding context. Additionally, the workload that corresponds to the mode or state may follow the changing mode or state.
As shown in
GPUs may render images in a variety of different ways. In some instances, GPUs may render an image using rendering and/or tiled rendering. In tiled rendering GPUs, an image may be divided or separated into different sections or tiles. After the division of the image, each section or tile may be rendered separately. Tiled rendering GPUs may divide computer graphics images into a grid format, such that each portion of the grid, i.e., a tile, is separately rendered. In some aspects, during a binning pass, an image may be divided into different bins or tiles. In some aspects, during the binning pass, a visibility stream may be constructed where visible primitives or draw calls may be identified. In contrast to tiled rendering, direct rendering does not divide the frame into smaller bins or tiles. Rather, in direct rendering, the entire frame is rendered at a single time. Additionally, some types of GPUs may allow for both tiled rendering and direct rendering.
Some aspects of graphics processing may utilize color spaces (i.e., a specific organization of colors). A color space may support a reproducible representation of color, such as via an analog or a digital representation. Also, a color space may help to understand the color capabilities of a particular device or digital file. For instance, when trying to reproduce color on a device, color spaces may show details of shadows/highlights or color saturation. There are a number of different types of color spaces or color models (i.e., an abstract mathematical model describing the way colors can be represented as tuples of numbers). For example, there are red (R) green (G) blue (B) (RGB) color spaces/models or luminance (Y) chrominance (UV) (YUV) color spaces/models.
Additionally, color spaces may be converted from one color space to another color space in a process referred to as color space conversion (i.e., the translation of the representation of a color from one basis to another). A color space conversion may occur in the context of converting an image that is represented in one color space to a representation in another color space. For instance, one objective of a color space conversion may be to make a converted image look as similar as possible to an original image. One example of a color space conversion is converting an RGB color space to a YUV color space, or vice versa.
In some aspects, the use of a YUV color space may be convenient for video streams of natural images. For example, it may be straightforward to encode and decode a full image (e.g., a one-to-one pixel ratio) between an RGB color space and a YUV color space. However, in an image processing pipeline that utilizes filtering from the YUV image, the encoding/decoding process may be difficult if the source image is non-linear (i.e., gamma) compressed with certain types of color space (e.g., a standard RGB (sRGB) color space).
Further, filtering may be utilized if a certain image (e.g., a YUV image) is part of an image processing or rendering pipeline that may apply scaling, rotations, or other arbitrary image access. If the source is linear RGB, then filtering may be performed directly from the resulting YUV. If the source is non-linear (i.e., gamma) compressed sRGB, it may not be possible to correctly filter from the resulting YUV as the Y/U/V components are accumulations of non-linear R/G/B components. Instead, each sample may be converted from YUV to sRGB, and then from sRGB to linear RGB before being filtered. Applying these conversions for all samples for an advanced (i.e., bi-cubic) filtering kernel may be expensive. This may be even more complex when dealing with sub sampled chroma.
As indicated above, YUV is a color encoding system based on human perception. For instance, Y=luminance (i.e., linear) or Y′=luma (i.e., non-linear) is the brightness value, to which the human eye is most sensitive. Another color encoding system based on human perception is YCbCr, which is similar to YUV except that the chrominance component is CbCr instead of UV. Chrominance (e.g., consisting of U/Cb (blue projection) and V/Cr (red projection)) is the color values to which the human eye is less sensitive, hence these values can be down-sampled. In some instances, YUV may be associated with analog television systems, while YCbCr may be the digital video equivalent.
As further indicated above, RGB and YUV may be utilized in different processes. For example, RGB may be utilized as a common color encoding system for computer images, while YUV may be typically utilized for a video transfer. The transfer between RGB and YUV may be a relatively straight forward process, such as the conversion of one channel in RGB (e.g., R/G/B) to a corresponding channel in YUV (e.g., Y/U/V). For instance, various industry standards may result in a weighted sum of three components of RGB or YUV (e.g., R/G/B or Y/U/V) plus an offset and/or a scale.
In some aspects, the rendering of content (e.g., color content) may be performed in multiple locations and/or on multiple devices, such as to divide the rendering workload between different devices. For example, the rendering may be split between a server and a client device, which may be referred to as “split rendering.” In some instances, split rendering may be a method for bringing content to client devices, where a portion of the graphics processing may be performed outside of the client device, e.g., at a server. In some aspects, the server may be at least one of: a phone, a smart phone, a computer, or a cloud server. Further, the client device may be at least one of: a headset, a head mounted display (HMD), display glasses, or smart glasses.
Split rendering may be performed for a number of different types of applications, e.g., virtual reality (VR) applications, augmented reality (AR) applications, and/or extended reality (XR) applications. In VR applications, the content displayed at the client device may correspond to man-made or animated content. In AR or XR content, a portion of the content displayed at the client device may correspond to real-world content, e.g., objects in the real world, and a portion of the content may be man-made or animated content. Also, the man-made or animated content and real-world content may be displayed in an optical see-through or a video see-through device, such that the user may view real-world objects and man-made or animated content simultaneously. In some aspects, man-made or animated content may be referred to as augmented content, or vice versa.
Split XR or AR systems may also introduce latency when delivering the rendered content to the client display. In some aspects, this latency may be even higher when rendering occurs on a server than compared to client rendering, but it may also enable more complex XR or AR applications. In addition, there may be non-negligible latency between the time a camera pose is computed and the time the content appears on the client display. For instance, a certain amount of latency may be present in split XR or AR systems.
As shown in
As indicated above, aspects of graphics processing may be associated with rendering or displaying different types of content, e.g., virtual reality (VR) content, extended reality (XR), or augmented reality (AR) content. The content may be rendered or created on a server, e.g., a computer or phone. To display this content, users may utilize different types of headsets or display glasses, which may be referred to as a client device. In some instances, when a user wants to use XR glasses for a long duration in the absence of a charging facility, it is desirable to save power at the server or client device. Also, when the battery of either the client device or the server is getting low (i.e., beyond a threshold percentage decided by the user), it is desirable to save power at the server or client device. Moreover, if a user would like to extend battery life voluntarily, then it is desirable to save power at the server or client device and provide a long battery life to either device.
Some solutions for power saving may be associated with reducing a frame resolution or frame refresh rate during the rendering/display process. Further, utilizing foveated rendering may reduce power usage and/or improve performance at the server/client device. Additionally, the rendering pipeline (e.g., at a graphics processing unit (GPU)) may utilize full color or chrominance data. If each step in the rendering pipeline is associated with the processing of full color/chrominance data, this may waste a large amount of power.
On the client device 404, the data packets 450 may be received from the server 402 via a reception process (e.g., a PCIE process 460). The data packets 450 may be de-packetized into content for the data during de-packetization process 470. The content for the data may also be decrypted during decryption process 472. Also, the content for the data may be decoded during decoding process 474. The client device 404 may also perform a color space conversion 480 on the content. Finally, after the color space conversion 480, the content may be displayed on display 490.
As shown in
Based on the above, it may be beneficial to process some steps in a split rendering process or a non-split rendering process without using full or polychrome color data. For example, it may be beneficial to process some steps in a split rendering process or a non-split rendering process using monochrome color data. It may also be beneficial to process some steps in a split rendering process or a non-split rendering process using a luminance component, rather than both a luminance component and a chrominance component.
Aspects of the present disclosure may process some steps in a split rendering process or a non-split rendering process without using full color data or polychrome color data. For instance, aspects of the present disclosure may allow for the processing of some steps in a split rendering process or a non-split rendering process using monochrome color data. Additionally, in some instances, aspects of the present disclosure may process some steps in a split rendering process or a non-split rendering process using a luminance component, instead of both a luminance component and a chrominance component. By doing so, aspects of the present disclosure may save a large amount of power at each of the devices in a split rendering process (e.g., the server and the client device) or a non-split rendering process. Accordingly, aspects of the present disclosure may reduce the amount of power utilized during color data processing in a split rendering process or a non-split rendering process.
As indicated herein, for split rendering processes, aspects of the present disclosure may save power at a server/client device by reducing the amount of data that is processed with full color/chrominance components. For instance, aspects of the present disclosure may reduce the amount of full color/chrominance data that is processed in the entire rendering pipeline (e.g., a GPU rendering pipeline) or a portion of the rendering pipeline. In order to do so, aspects of the present disclosure may limit the type of data that is processed to monochrome color data, rather than processing the data as full color/chrominance data.
As shown in
On the client device 504, the data packets 550 may be received from the server 502 via a reception process (e.g., a PCIE process 560). The data packets 550 may be de-packetized into content for the data during de-packetization process 570, where this step may be performed using monochrome color data. The content may include at least one of monochrome color content or a luminance component. The content for the data may also be decrypted during decryption process 572, where this step may also be performed using monochrome color data. Also, the content for the data may be decoded during decoding process 574, where this step may be performed using monochrome color data.

Additionally, at client device 504, aspects presented herein may utilize the following stages: (7) reception of data packets via a PCIE received on client device Wi-Fi, as shown at 560; (8) de-packetization of the multiple data packets into content, as shown at 570; (9) decryption of content and/or a video stream, as shown at 572; (10) video decoding using solely monochrome content (e.g., using solely a Y-plane and/or luminance component), as shown at 574; (11) perform a color space conversion from one color format to another color format (e.g., convert from an NV12 format to an RGB format), as shown at 580; and (12) send the content to a display after the color space conversion, as shown at 590. Certain color formats (e.g., NV12 color format) may be a biplanar format with a full sized Y plane followed by a single chroma plane with weaved U and V values. NV12 may also be an intermediate YUV 4:2:0 video format. At 590, client device 504 may send content (e.g., RGB content) to a field sequential display (FSD)/RGB display at the client device 504.
