摘　　要：本文在研究MIL-STD-1553B总线远程终端协议逻辑的基础上,为实现10种消息类型的全部识别处理,采用消息识别的设计方法将总线通信的消息归纳为接收消息、发送消息和地址无效消息3类,并针对每类消息按照细分的消息类型分别处理,基于FPGA技术和有限状态机技术设计实现具有参数可配置的远程终端协议模块。软硬件仿真测试结果表明,本文设计的远程终端协议模块满足MIL-STD-1553B总线远程终端协议功能需求,具有工程可实现性并能与某1553B仿真卡建立总线通信,为设计开发其专用协议产品提供一定技术参考。Based on the study of MIL-STD-1553B bus remote terminal protocol logic,this paper designs a method of message recognitionto realize the identification of all 10 message types.In this method,bus messages are classified into three kinds of communication information,such as receiving communication,sending communication and invalid address communication,and then deal with all the subdivision of the message type.A remote terminal protocol logic is designed in VHDL language with the FPGA and finite state machine technology,which has the functions of parameters configurable.Results of hardware tests and software simulations show that the remote terminal module designed in this paper meets the function of MIL-STD-1553B bus remote terminal protocol,and has engineering realizability and can establish bus communication the 1553B simulation card.At the same time,the design method provides some technical reference for the design and development of its special protocol products.
