摘　　要：分析IEEE1149.5标准定义的MTM总线协议,对MTM总线模块间的数据通信体系进行功能需求分析,提出MTM总线模块间通信体系的设计方案。通过采用不同的驱动电路,构建和实现MTM总线模块间的短距离通信体系和长距离通信体系。应用结果表明该设计是正确可行的。This paper analyzes the MTM-Bus protocol defined by IEEE standard 1149.5, and the functional requirement of data communication architecture among MTM bus modules according to the request of protocol and the practical application, presenting a design project on the communication system among the MTM-Bus modules. The communication among the MTM-Bus modules uses the different driving circuit and realizes the communication system among MTM-Bus modules with short distance communication system and the long distance communication system. Application results show that the design is feasible.
