The present invention is further described below with reference to the accompanying drawings and embodiments. In the drawings:
For clearer understanding of the technical characteristics, aims and effects of the present invention, specific embodiments of the present invention are now described in detail with reference to the accompanying drawings.
Referring to
Referring to
Specifically, the first processor 10 may register services to execute corresponding functions. In the disclosed embodiments of the present invention, the services may be preset services. For example, obtaining card information may be used as a preset service. When a preset condition is satisfied, after the second processor establishes a connection with the first processor by sending a synchronization frame, the first processor may register the preset service to perform the function of the preset service, e.g., obtaining the card information.
In the disclosed embodiments of the present invention, different services may have different functions. For example, a service for obtaining card information may be registered. Other types of services, e.g., services for obtaining status information, control information, etc., may also be registered in the disclosed embodiments of the present invention. Each one service may correspond to one port, that is, information obtained by the service may be transmitted through a port corresponding to the service. The port here may be referred to the first-type port described above.
Therefore, in the disclosed embodiments of the present invention, because a plurality of ports (the first-type ports described above) may be extended to correspond to different services, respectively, and different transmission layers may be invoked according to actual communication transmission demands to transmit information to interfaces (e.g., a USB interface, a shared memory interface, etc.) of the physical layer to support extending a plurality of transmission layer protocols. For example, for a first service, a transmission layer 1 may be invoked to transmit information, and for a second service, a transmission layer 2 may be invoked to transmit information. Different transmission layers may use different transmission layer protocols.
The second processor 20 may send a sync frame (synchronization frame) to the first processor 10. The first processor 10 may be further configured to reply an acknowledgement frame (ACK) after receiving the sync frame to establish a connection between the first processor 10 and the second processor 20. In the disclosed embodiments of the present invention, when a preset condition is satisfied, the second processor 20 may initiate the connection establishment process, that is, may send the sync frame. The preset condition may include boot, restart, and other performing initialization moments.
It should be understood that in the disclosed embodiments of the present invention, there is no sequential order in establishing the connection between the first processor 10 and the second processor 20 through sync and ACK and registering the service by the first processor 10. The first processor 10 may register the service either before or after establishing the connection.
The second processor 20 may execute service discovery and register a client corresponding to the service. In one embodiment, the client registered by the second processor 20 may correspond to the service registered by the first processor 10. Further, similar to the service registered by the first processor 10, the client registered by the second processor 20 may correspond to a corresponding port to transmit information to the transmission layer through the port, and to transmit the information to a corresponding physical interface through the port of the transmission layer.
After the second processor 20 registers the client, the first processor 10 and the second processor 20 may perform information exchange. Specifically, when performing the information exchange, a data packet format as shown in
In one embodiment of the present invention, the port number may be a port number of the second-type port described above, which may be used to mark to which physical interface the data packet is transmitted. For example, when the physical interfaces include a USB interface and a shared memory interface, the data packet may be correctly transmitted to the corresponding physical interface through the port number to implement the exchange with the second processor 20. Therefore, after the data packet is transmitted to the physical layer, the field of port number may be deleted. That is, the data packet transmitted to the opposite end may not include the field of port number.
In one embodiment of the present invention, different physical interfaces (hardware interfaces) may have different port numbers. Therefore, by assigning a port number in the data packet, the data packet may be correctly forwarded, such that the information obtained by the service registered by the application layer may be transmitted through the exact physical interface. Therefore, the dual-core communication device in the disclosed embodiments of the present invention may support extending a plurality of physical interfaces (e.g., extending a plurality of physical layer protocols).
The service ID may be an ID number of the registered service. The client ID may be an ID number of the client corresponding to the service. The control bit may be used to identify whether the data packet is a request packet, a reply packet, etc. The data may use a ‘type-len-value’ format, where ‘type’ is used to represent a type of the entire data block, ‘len’ is used to represent a size of the ‘value’ field, and ‘value’ is the data field.
In the disclosed embodiments of the present invention, one service may have to transmit a plurality of data packets, and, thus, the message ID may represent a sequence number of the transmitted data packet. The data ID may be used to distinguish message type of the data packet. Each data packet may include a plurality of data with different types, thus, one message ID may correspond to a plurality of ‘type’. For example, a signal strength, a network format, and other information may be transmitted as one data packet, and types of different data blocks may be represented in the data field by ‘type’. Therefore, one data packet may transmit various information belonging to a same one message type.
It should be understood that the data packet format illustrated in
In one embodiment of the present invention, specifically, the first processor 10 may be configured with a first logical port corresponding to a preset service, and configured with a second logical port corresponding to a physical interface of the first processor. Information obtained by the preset service may be transmitted to the second logical port through the first logical port, and then transmitted to the second processor through the physical interface of the first processor. The second processor 20 may be configured with a third logical port corresponding to a client, and configured with a fourth logical port corresponding to a physical interface of the second processor. Information received by the physical interface of the second processor may be transmitted to the third logical port through the fourth logical port, and then transmitted to the client.
In the disclosed embodiments of the present invention, when the second processor 20 shuts down or restarts abnormally, the second processor 20 may close the client and the ports. When the second processor 20 returns to normal, the connection with the first processor 10 may be re-established by sending a sync frame to re-execute the processes of registering the service, registering the client, etc., and to perform information exchange.
Similarly, if the first processor 10 shuts down or restarts abnormally, the first processor 10 may close the corresponding service and ports. When the first processor 10 returns to normal, the connection with the second processor 20 may be re-established by sending a sync frame to re-execute the processes of registering the service, registering the client, etc., and to perform information exchange.
In the dual-core communication device in the disclosed embodiments of the present invention, a C/S communication architecture may be adopted between the first processor and the second processor to share information. Therefore, the first processor 10 may share the obtained information with the second processor 20, and, thus, the second processor 20 may obtain the information instantly. Further, different ports may be registered for different services to perform corresponding transmission, which may support extending a plurality of transmission layer protocols and support extending a plurality of physical layer protocols.
