In case you haven t realized it, building computer systems is hard. As the complexity of the system gets greater, the task of building the software gets exponentially harder. As in any profession, we can progress only by learning, both from our mistakes and from our successes. This book represents some of this learning written in a form that I hope will help you to learn these lessons quicker than I did, or to communicate to others more effectively than I did before I boiled these patterns down.

This project is created using the Keil ARM CA Compiler. The Logic Analyzer built into the simulator may be used to monitor and display any variable or peripheral I/O register. It is already configured to show the PWM output signal on PORT3.0 and PORT3.1 This ARM Example may be debugged using only the uVision Simulator and your PC--no additional hardware or evaluation boards are required. The Simulator provides cycle-accurate simulation of all on-chip peripherals of the ADuC7000 device series. You may create various input signals like digital pulses, sine waves, sawtooth waves, and square waves using signal functions which you write in C. Signal functions run in the background in the simulator within timing constraints you configure. In this example, several signal functions are defined in the included Startup_SIM.INI file.

This directory contains the memtest 8051 firmware for the Anchor Chips EZ-USB chip. The purpose of this software is to test the different memory segments in the Ez-Usb chip. This example will output the string "good" on the 7 segment LED if the mem test passes, or it will output the first address where the memtest fails.

ABAQUS is a general purpose finite element analysis program which is widely used to analyses mechanical, structure and civil engineering problems. Abaqus has some special feature for analysing fracture mechanics problems, and therefore it is a main tools for the FE-analysis in the Fracture Group at the Mechanical Engineering at Glasgow Universtity. The software which can transfer data from Abaqus into a Matlab readable environment has been developed as a part of a research program in Constraint Estimation in Fracture Mechanics. This research program was funded by a grant from the Defence Research Agency through Prof. J. Sumpter.

uc/os-ii for 8051 This package provides the sources required to use the uC/OS-II v2.00 real time kernel on the 8051 processor. To use this package you will need the TASKING C Compiler toolset v6.0r1 or higher. For info on TASKING products you can contact our Web-site at: http://www.tasking.com Unzip the zipfile in the root of the drive where you also installed the uC/OS-II general sources. The following directories will be added: \SOFTWARE\UCOS-II\8051 This directory contains the microprocessor specific source code \SOFTWARE\UCOS-II\ex1_8051r This directory contains the project files for the first example \SOFTWARE\UCOS-II\ex2_8051r This directory contains the project files for the second example

软件测试的目的决定了如何去组织测试。如果测试的目的是为了尽可能多地找出错误,那么测试就应该直接针对软件比较复杂的部分或是出错比较多的位置。如果测试目的是为了给最终用户提供具有一定可信度的质量评价,那么测试就应该直接针对在实际应用中会经常用到的模块重点测试。不同的机构会有不同的测试目的;相同的机构也可能有不同测试目的,可能是测试不同区域或是对同一区域的不同层次的测试。在谈到软件测试时,许多人都引用Grenford J. Myers在《The Art of Software Testing》一书中的观点:
