A method to parse 1553B bus communication protocol to achieve communication between remote terminals(RT) and bus by FPGA programming is introduced in this paper. The communication system,transmission protocol and communica⁃tion method of 1553B bus are elaborated. The the relationship between program modules in FPGA and their functions are ana⁃lyzed. The correctness and reliability of FPGA program were proved by a test.% 详细介绍了一种使用FPGA编程，解析1553B总线通信协议以实现远程终端（RT）与总线通信的方法，阐述了1553B总线的通信体系、传输协议和通信方法，深入解析了FPGA中各程序模块之间的关系及功能，并通过试验证明了FPGA程序的正确性与可靠性。
