摘　　要：MⅢ总线是某军用飞机上的一种非标准的并行信息传输总线标准,总线地址数据独立,采用半双工工作方式,总线终端工作状态分为总线控制、远程终端和总线监控。在外场测试实验系统中,总线终端接口卡用于和系统中的仿真设备通信,PC机通过CPCI接口控制接口卡。采用一板复用的设计原则实现接口卡硬件。板载固件程序根据设备工作要求划分为具有层次性的逻辑子模块,采用硬件描述语言逐个实现并进行综合。经外场实验测试,接口卡各项性能指标满足设计要求。The MIII bus is a data communication bus transmitted parallelly with separate data and address bus- ses, it works at half-duplex mode, the terminal works at three different modes which is bus controller, remote terminal and monitor terminal. The card is used to communicate with simulation equipment in the out-field tes- ting system, and controlled through CPCI interface by the computer. The hardware of the card is realized with design-reuse principle. The on-board program is divided into different modules according to the functional re- quirements, the logical functions of the modules are realized and synthesized in hardware description language. Through the test, the performance meets the design requirements.
