摘　　要：文中的研究对是以MXI-2作为连接总线的外挂控制器式VXI总线系统,介绍系统的硬件结构,具体分析系统对中断请求的处理过程及时序关系,总结基于VISA库的中断服务程序的编程流程。VXIbus system connected to the external controller with the MXI - 2 bus is the object in this paper. The hardware architecture of this system is introduced first. The handling process of interrupt and the process time sequence are analyzed in detail later. At last, the flowchart of the interrupt service routime based on the VISA library is concluded.
