GPIB-VXI转换器是外计算机与VXIbus系统之间的桥梁。本文从GPIB-VXI控制器的功能出发,介绍了其硬件电路的基本原理与实现方法。并对其中的地址译码控制、总线转换与驱动、TTL触发电路的设计等若干问题进行了详细地分析。这些内容对其它VXIbus模块的设计也有一定的参考价值 GPIB-VXI converter is a bridge between the external computer and the VXIbus system. This text sets out from the function of GPIB-VXI controller, introduced its hardware circuit basic principle and method of realization. And some problems such as address decoding control, bus conversion and driving, TTL triggering circuit design are analyzed in detail. These contents also have certain reference value to the design of other VXIbus modules
