现代先进微处理器有非常高的集成度和复杂度，又有寄存器堆、Cache等嵌入式部件，而且芯片管脚数相对较少，必须要有一定的自测试设计和其它的可测试性设计来简化测试代码，提高故障覆盖率。本文简要讨论NRS4000微处理器芯片的以边界扫描测试为主体，以自测试为补充的可测试性设计框架。着重介绍芯片的边界扫描设计和芯片中译码控制器PLA和微程序ＲＯＭ以及采用内嵌RAM结构的指令Cache和寄存器堆的内建自测试设计。仿真结果表明，这些可测试性设计大大缩短了测试代码的长度。-modern microprocessors have a very high degree of integration and complexity, there Register pile, Cache such as embedded components, but Chip few relatively small, There must be the self-test design and testing of other design code to simplify testing, fault coverage. This paper briefly discussed Key words microprocessor chip to the boundary-scan test as the mainstay, Since the test to add to the test design framework. Highlighting the boundary-scan chip design and chip decoder PLA and micro-controller procedures and the use of embedded ROM RA M structure of the instruction cache and register stack of built-in self-test design. The simulation results show that these tests can greatly shorten the design of the test code length.

今天，64位计算正在逐步取代32位计算，并且，这个转换的过程会对当前软件的形式带来巨大的冲击。其中，转换需要移植相关的应用程序及重写系统软件，这当中还包括操作系统等等。在本文中，将主要探讨64位软件世界中的主角--64位Windows及64位的通用语言运行时库（CLR）的结构，另外，还将涉及移植到64位平台的种种有利之处。-Today, the 64-bit computing is gradually replaced by 32-bit computing, and that this process of conversion software on the current form of heavy blows. Among them, the conversion needs of transplant-related applications and rewrite the system software, which of them, including the operating system and so on. In this article, will be focused on the 64-bit software in the world of the protagonist 64 Windows and 64-bit common language runtime (CLR) of the structure, will also be involved in transplanted into 64-bit platform for all sorts of advantages.
