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.

A one-dimensional calibration object consists of three or more collinear points with known relative positions. It is generally believed that a camera can be calibrated only when a 1D calibration object is in planar motion or rotates around a ¯ xed point. In this paper, it is proved that when a multi-camera is observing a 1D object undergoing general rigid motions synchronously, the camera set can be linearly calibrated. A linear algorithm for the camera set calibration is proposed，and then the linear estimation is further re¯ ned using the maximum likelihood criteria. The simulated and real image experiments show that the proposed algorithm is valid and robust.-A one-dimensional calibration object con sists of three or more points with Conic kno wn relative positions. It is generally believe d that a camera can be calibrated only when a 1D ca libration object is in planar motion or rotates around a

This article describes a radio-frequency controlled mobile robot, monitorizated and controlled through an embedded Java microcontroller. This project included the mobile robot design and building, as well as the control and communication software. This multidisciplinary project allowed students to learn and apply different areas of knowledge, including mechanical robot construction, electrical motor control, Java and C language programming, web graphical user interface design, real time control and RF communications. The interface with user is made with a friendly Web page allowing the control of the robot motion in real time. The user can also visualize the orientation and x-y coordinates of the robot.
