摘　　要：本文详细介绍了CRC基本原理和HDLC协议的具体内容,基于某雷达系统的实际需要,在FPGA中实现了HDLC协议的同步串口通信,并与串口通信板完成对接,测试表明此同步串口设计准确性高、稳定性好,具有很好的推广性和继承性。This paper provides a detailed introduction to the basic principle of cyclic redundancy check(CRC)and the specifics of the HDLC protocol.Based on the actual needs of a radar system,the synchronous FPGA-based serial communication is implemented using HDLC protocol.In addition,data exchange between the designed synchronous serial port and a serial communication board is carried out.The test results show that the proposed synchronous serial port has high accuracy and stability,making it highly applicable and inheritable.

关 键 词：FPGA HDLC协议 CRC校验码
