摘　　要：VME总线接口的设计是VXI总线嵌入式控制器设计的一个重点。本文详细讨论了运用VMEbus接口控制器VIC068A和地址控制器VAC068A进行ISA总线VME总线转换的电路设计方法,给出了优先中断总线的设计方案。VXIbus is VMEbus extensions for instrumentation. In the process of designing embedded computer,the VMEbus interface controlling circuits is important which is also the most difficult part.This paper fully discussed how to use VMEbus interface controller VIC068A and VMEbus address controller VAC068A to design the translating circuit from ISAbus to VMEbus,and it also gives out a scheme for priority interrupt bus.
