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.

飞行控制系统方案。整个系统由传感器组、飞控计算机、任务管理计算机、舵机、表决电路等主要部件和电源、外总线、通信设备、地面站等辅助设备组成。无人机、起落架、发动机、任务设备、燃油系统、环控系统等是被监控对象。其中,关键传感器采用相似或者非相似三余度;飞控计算机采用“主备备”式三余度飞控机算机;舵机采用二余度电动舵机;表决逻辑由高可靠性单余度数字逻辑电路和双路开关实现。-Flight Control System program. The entire system is composed of sensors, the flight control computer, task management computer, steering gear, the division circuit components and the main power source, Foreign bus, communications equipment, ground support equipment components. UAV, landing gear, engine, mission equipment, fuel systems, environmental control systems are monitoring targets. Among them, critical sensor similar to three or similar non- I; The flight control computer "equitable preparations," I was three-flight control machine; Rudder I was using two electric steering; vote by the logic of high-reliability and redundancy digital logic circuit and a two-way switch.

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.
