关于VXI与MXI有不少文章进行介绍,但都比较零散,难以形成整体概念。本文简要叙述VXI和MXI的原理及其设计要点。据此,可以全面了解设计一个VXI/MXI系统时所应做的工作。全文共分两个部分,第一部分介绍VXI,第二部分介绍MXI。1 VXI概述符合工业标准的卡式仪器已经减少了层迭式仪器系统的物理尺寸,多台仪器间的严格定时与同步,以及高于GPIB(1Mbytes/see)的传输速率。VME总线的这种模块式结构的高效率、较宽的应用范围及商业上的成功使之特别
VXI and MXI have a lot of articles on the introduction, but are more fragmented, it is difficult to form the overall concept. This article briefly describes the principle and design of VXI and MXI. This gives you a good overview of what you should do to design a VXI / MXI system. The full text is divided into two parts, the first part introduces VXI, the second part introduces MXI. 1 VXI Overview Industry-standard card-based instrumentation has reduced the physical size of stacked instrumentation systems, stringent timing and synchronization among multiple instruments, and higher than GPIB (1Mbytes / see) transfer rates. This modular structure of the VME bus makes it particularly efficient, with a wide range of applications and commercial success
