In order to accelerate the car electric bus communication rate in the integrated architecture, combined with the requirements of processor project on integration-platform, with the combination of dual bus and complementary on the function and collocation of CAN and FlexRay, a Field Programmable Gate Array(FPGA)-based bus interface unit is designed. The module function of the internal CAN bus controller, FlexRay bus controller, RapidIO bus interface and Ethernet through FPGA is completed. The control and extension of high speed interface is realized, and the module interface configurable is made. Test proves that the CAN interface and FlexRay interface work properly under the specified baud rate, and each performance index meets the project requirement.
