俄制计算机板级替换的研究与实现

Study on Board-Level-Replacement of the Computers Made by Russia

俄制飞机相关设备的国产化一直是我军研究的一项重要课题,根据某型俄制飞机计算机国产化的实际需求,并结合此过程中的一些成功经验,对此类型计算机CPU(运算器和控制器)的板极替换进行了深入研究;此类计算机由专用小规模集成电路组成,这里使用FPGA技术实现运算器和控制器的板极替换,详细介绍了该过程中板极测试平台、启停控制电路和复位电路的设计以及冒险与竞争问题的解决方法;该设计方案已经实际使用,实验结果表明该设计方案正确高效,实现了需求所设定的目标。

Abstract; Local production of The plane equipments made by Russia is an important issue in China. The article is based on the require ment of a muscovite plane computer localization, and the experience in the development. We have a deep study on the hoardlevelreplace ment. This computer is made up of small scale integrated circuit. Wu use FPGA to achieve the boardlevelreplacement of the arithmetic unit and control unit. The article mainly introduce the solution method of boardlevel test platform, startstop control circuit, reset circuit and the solution method of the adventure and competition. The design has practical use. The experimental results show that the design is cor rect and achieve the design goal.
