[Purposes]To meet the communication interaction requirements between the CAN bus and UART interface,this paper presents an FPGA-based communication forwarding scheme,focusing on the implementation of bidirectional data exchange between the two protocols.[Methods]The system adopts an FPGA as the core control unit,where VHDL-based protocol parsing modules are developed to handle CAN bus and UART protocol analysis,while the transmission and reception modules achieve bidirectional communication between the two interfaces.[Findings]Functional verification of the designed communication module was conducted on the Vivado platform.The experimental results demonstrate that the system can stably achieve bidirectional data transmission between the CAN bus and UART interface,meeting the requirements of high reliability and low latency.[Conclusions]The proposed FPGA-based communication forwarding design validates the feasibility of implementing inter-protocol communication between CAN bus and UART within FPGA hardware.The scheme exhibits promising potential for engineering applications and further research promotion.
