基于FPGA的ESC芯片冗余通信接口设计OA

To achieve independent controllability and enhance the communication reliability of the EtherCAT Slave Controller(ESC),this paper proposes an FPGA-based redundant communication interface.The design adopts a modular architecture with the innovative integration of hardware modules,including link redundancy processing,multi-path frame forwarding,EtherCAT frame parsing,and configurable timing compensation.It supports dual-link redundancy backup and enables real-time detection and isolation of erroneous frames.The system performs automatic frame forwarding and achieves microsecond-level latency through parallel hardware processing.FPGA test results demonstrate that the interface maintains stable communication during single-link failures while consuming minimal hardware resources.The proposed solution effectively improves the fault tolerance and real-time performance of ESC communications,laying a solid technical foundation for the independent development of high-reliability industrial communication chips.
