Problems solved by technology
At present, when designing board products, it is necessary to carry out pre-function planning for all pins of the connector. After the planning is completed, all board products must be developed according to regulations, and the bus and level must be completely matched. It leads to lower flexibility; moreover, connectors with multiple pins increase the cost, are prone to poor compatibility, and have a high failure rate

The embodiment of the invention discloses a communication interface device for inter-board communication, a board card and a data processing method, and relates to the technical field of embedded systems, and the communication interface device comprises an FPGA module and a connector module which are arranged on a PCB; the FPGA module performs protocol conversion processing on first data sent by other modules and received through the second communication interface, generates second data matched with the first communication interface and sends the second data to the connector module through the first communication interface; and the FPGA module performs protocol conversion processing on third data sent by the connector module and received through the first communication interface, generates fourth data matched with the second communication interface and sends the fourth data to other modules through the second communication interface. According to the communication interface device, the board card and the data processing method, a normalized inter-board bus function can be realized, the number of communication buses and pins of a connector are reduced, and communication compatibility of various platforms can be realized.
Description
technical field [0001] The invention relates to the technical field of embedded systems, in particular to a communication interface device, board and data processing method for inter-board communication. Background technique [0002] With the rapid development of integrated circuit technology, a variety of boards are installed in the car to realize various functions such as controlling the operation of the vehicle, collecting external images, performing image processing, and performing identity recognition. Connectors are provided in different boards, and the compatibility between the multi-pin connector and the less-pin connector is relatively poor. With the modularization of automotive electronic products and the shortening of the development cycle, it is required to have adaptability between different main boards and different backplanes, and connectors with multiple pins need to be provided for different boards. Even though board products have low requirements for the n...
