[0042] Example 1

[0043] Smart devices often use low-speed interfaces such as Serial Peripheral Interface (SPI) and Inter-Integrated Circuit (I2C) to communicate with external devices. In existing technologies, only one interface can operate at a time, while the others remain idle, preventing simultaneous data transmission and resulting in low interface resource utilization. For further information, please refer to [link to relevant documentation / reference]. Figure 1 This application provides a multi-interface data transmission system 100, including: multiple communication interfaces 110, an arbitration unit 120, and an APB bridging unit 130; each of the communication interfaces 110 is electrically connected to the arbitration unit 120 and a communication device 200 respectively; the arbitration unit 120 is also electrically connected to the APB bridging unit 130 (APB_bridge); the APB bridging unit 130 is also electrically connected to multiple external devices 300 respectively;

[0044] Each of the communication interfaces 110 is used to obtain communication data from the communication device 200 and send the obtained communication data to the arbitration unit 120 respectively;

[0045] The arbitration unit 120 is used to perform protocol conversion on each of the communication data to obtain multiple target communication data; extract the access target address carried in each of the target communication data; determine the scheduling order of each of the target communication data according to each access target address, the scheduling order including: parallel scheduling order and time-division scheduling order; and send each of the target communication data and the access target address corresponding to each of the target communication data to the APB bridging unit 130 according to the scheduling order.

[0046] The APB bridging unit 130 is used to transmit the target communication data to the corresponding external device 300 according to the target address.

[0047] In this embodiment, the communication interface 110 includes, but is not limited to: Serial Peripheral Interface (SPI), Improved Inter-Integrated Circuit (I3C), Inter-Integrated Circuit (I2C), Universal Asynchronous Receiver / Transmitter (UART), General Purpose Input / Output (GPIO), Controller Area Network (CAN), and Local Interconnect Network (LIN). Each communication interface 110 is electrically connected to the communication device 200 and simultaneously connected to the arbitration unit 120.

[0048] When communication device 200 transmits data to multiple external devices simultaneously through multiple communication interfaces 110, each communication interface 110 first transmits its received communication data to arbitration unit 120. Arbitration unit 120 first performs protocol conversion on each communication data to obtain adapted target communication data, then extracts the access target address from each target communication data, and determines the scheduling order by verifying the uniqueness of the address—parallel scheduling order is configured for target communication data accessing different external devices 300, and time-division scheduling order is configured for target communication data accessing the same external device 300. Subsequently, arbitration unit 120 sends each target communication data and its corresponding access target address to APB bridging unit according to the scheduling order. APB bridging unit then transmits each target communication data to the corresponding external device 300 based on the access target address.

[0049] It is understandable that the protocol conversion and scheduling of the arbitration unit 120 breaks the limitation that only one interface can work at the same time in the traditional multiple low-speed interfaces. It supports parallel data transmission of multiple interfaces accessing different external devices 300 at the same time, and can also solve the conflict problem of multiple interfaces accessing the same external device 300 through time-sharing scheduling. At the same time, it allows various interfaces to share the access path of the APB bridging unit 130, improves the access bandwidth, and makes the upper-layer software more flexible in configuring multiple interfaces.

[0050] In one embodiment, each of the communication interfaces 110 corresponds to a different communication protocol. The step of converting each of the communication data into a protocol to obtain multiple target communication data includes: converting the communication protocol corresponding to each of the communication data into the APB bus protocol, and determining each of the protocol-converted communication data as target communication data.

[0051] In this embodiment, each communication interface 110 is adapted to different communication protocols such as SPI, I3C, I2C, UART, GPIO, CAN, and LIN. The communication data obtained by each interface from the communication device 200 also carries the format characteristics of the corresponding protocol. The arbitration unit 120 performs targeted conversion processing on the original protocol type of each communication data, converting all communication data with different protocol formats into the APB bus protocol format. Then, the communication data after the protocol conversion is determined as the target communication data. This allows communication data that was originally based on different protocols and could not be directly transmitted through the APB bridging unit 130 to be adapted to the unified transmission format of the APB bus, eliminating transmission compatibility barriers between different protocols and ensuring the uniformity and smoothness of the subsequent scheduling of all target communication data by the arbitration unit 120.

[0052] In one embodiment, determining the scheduling order of each target communication data according to each of the access target addresses includes: performing uniqueness verification on each of the access target addresses; configuring the target communication data corresponding to at least two access target addresses with the same verification result as a time-sharing scheduling order; and configuring the target communication data corresponding to at least two access target addresses with different verification results as a parallel scheduling order.

[0053] In this embodiment, when the arbitration unit 120 determines the scheduling order based on the access target address of each target communication data, it first performs a uniqueness check on all the extracted access target addresses one by one. After the check is completed, it performs differentiated scheduling configuration based on the result. The target communication data corresponding to the access target addresses with different check results are configured as parallel scheduling order, and the target communication data corresponding to at least two access target addresses with the same check result are configured as time-sharing scheduling order.

[0054] In this process, address uniqueness verification provides a basis for the selection of scheduling mode, allowing the arbitration unit 120 to automatically distinguish between parallel and time-sharing scheduling logics based on the actual access needs of each target communication data to peripheral devices. Parallel scheduling is adopted for the needs of accessing different external devices 300, so that data from multiple interfaces can be transmitted simultaneously, fully releasing the transmission capacity of the APB bus. Time-sharing scheduling is adopted for conflicting needs of accessing the same external device 300, avoiding transmission conflicts caused by multiple data accessing the same peripheral device at the same time.

[0055] In one embodiment, configuring the target communication data corresponding to at least two access target addresses with different verification results into a parallel scheduling order includes: assigning the same transmission channel identifier to the target communication data corresponding to at least two access target addresses with different verification results, and configuring a synchronization transmission trigger instruction; binding the target communication data corresponding to at least two access target addresses with different verification results to the corresponding transmission channel identifier and the synchronization transmission instruction; and determining the transmission rules of each bound target communication data into a parallel scheduling order.

[0056] In this embodiment, when the arbitration unit 120 configures the parallel scheduling order for target communication data corresponding to access target addresses with different verification results, it first assigns the same transmission channel identifier to these target communication data, configures a synchronous transmission trigger instruction, then associates and binds each target communication data with the corresponding transmission channel identifier and synchronous transmission trigger instruction, and finally determines the transmission rules of each target communication data after binding as the parallel scheduling order.

[0057] This configuration process achieves the unification of transmission path for multiple target communication data through a unified transmission channel identifier. With the help of synchronous transmission triggering instructions, it ensures that multiple data can start transmission in the same preset time sequence, allowing multiple target communication data accessing different external devices 300 to achieve synchronous parallel transmission based on unified rules, making full use of the transmission bandwidth of the APB bus.

[0058] In one embodiment, configuring the target communication data corresponding to at least two access target addresses with the same verification result as a time-division scheduling order includes: sorting the target communication data corresponding to at least two access target addresses with the same verification result in sequence according to preset priority configuration information; assigning sequentially increasing transmission timing numbers to each of the sorted target communication data and associating them with the corresponding access target addresses; and determining the transmission rules of each of the target communication data with transmission timing numbers as a time-division scheduling order.

[0059] In this embodiment, when the arbitration unit 120 configures the time-sharing scheduling order for target communication data corresponding to at least two access target addresses with the same verification result, it first sorts these target communication data that need to access the same external device 300 according to the preset priority configuration information, and then assigns a sequentially increasing transmission timing number to each sorted target communication data. At the same time, it associates and binds each number with the access target address of the corresponding target communication data, and determines the transmission rules of each target communication data with the transmission timing number as the time-sharing scheduling order.

[0060] This configuration process uses a preset priority as the sorting basis, giving the transmission order of multiple conflicting data a clear and configurable criterion. The sequentially increasing transmission timing numbers define a clear order of transmission for the multiple data streams. The association and binding of the number with the access target address ensures that the timing number always matches the access requirements of the corresponding peripheral device, avoiding the problem of address and data transmission order being disordered.

[0061] In one embodiment, sending each target communication data and the corresponding access target address to the APB bridging unit 130 according to the scheduling order includes: sorting each target communication data according to the scheduling order to generate a data sending queue; associating each access target address with the corresponding target communication data; and sending each target communication data and the corresponding access target address to the APB bridging unit 130 sequentially according to the order of the data sending queue.

[0062] In this embodiment, when the arbitration unit 120 sends the target communication data and the corresponding access target address to the APB bridging unit 130 according to the scheduling order, it first sorts all the target communication data to be transmitted in a unified manner according to the determined parallel or time-sharing scheduling order to generate a regular data transmission queue. Then, it associates and binds each target communication data with its corresponding access target address one by one. Finally, it transmits each group of bound target communication data and access target address to the APB bridging unit 130 in strict accordance with the predetermined order of the data transmission queue.

[0063] In one embodiment, before transmitting each target communication data to the corresponding external device 300 according to each of the access target addresses, the method further includes: matching each target communication data to a corresponding external device 300 according to each of the access target addresses.

[0064] In this embodiment, before transmitting the target communication data to the corresponding external device 300 based on each access target address, the APB bridging unit 130 first performs a matching operation between the access target address and the external device 300. Specifically, it extracts the access target address corresponding to each group of received target communication data, maps each access target address to the external device 300, and accurately matches a unique corresponding external device 300 for each target communication data according to the address matching result. Data transmission is then performed after the matching is completed.

[0065] This application provides a multi-interface data transmission system 100, comprising: multiple communication interfaces 110, an arbitration unit 120, and an APB bridging unit 130; each communication interface 110 is electrically connected to the arbitration unit 120 and a communication device 200; the arbitration unit 120 is also electrically connected to the APB bridging unit 130; the APB bridging unit 130 is also electrically connected to multiple external devices 300; each communication interface 110 is used to acquire communication data from the communication device 200 and send the acquired communication data to the arbitration unit 120; the arbitration unit 110... 20 is used to perform protocol conversion on each of the communication data to obtain multiple target communication data; extract the access target address carried in each of the target communication data respectively, and determine the scheduling order of each of the target communication data according to each access target address, the scheduling order including: parallel scheduling order and time-division scheduling order; send each of the target communication data and the access target address corresponding to each of the target communication data to the APB bridging unit 130 according to the scheduling order; the APB bridging unit 130 is used to transmit each of the target communication data to the corresponding external device 300 according to each access target address. This application realizes efficient and orderly transmission of multiple low-speed interface data, which not only solves the conflict problem of multiple interfaces accessing peripherals and breaks the limitation of single interface single operation, but also improves data transmission bandwidth and interface utilization.
