中文摘要:

      针对近年来飞机含80C486处理器电路板修理现状，为掌握该系列板件的修理保障能力，迫切需要开展其软硬件测试技术研究。在对80C486处理器进行系统阐述基础上，设计并研制一块基于80C486处理器的多功能实验板，给出该板的硬件电路图与软件流程框图，并基于汇编语言进行功能调试，实验结果表明其有效性。所做的含80C486处理器的正向设计与软件编程研究工作为修理含80C486控制器板的机载模块奠定了基础，同时也为后续含有该型控制器的板件测试和修理提供了借鉴方法，并对同类型其他控制器的测试提供参考。

英文摘要:

      In view of the current situation of the circuit board repair of 80C486 processor in aircraft in recent years,in order to master the repair ability of this series of boards,it is urgent to carry out the research of software and hardware test technology.On the basis of system description of 80C486 processor,a multi functional experimental board based on 80C486 processor is designed and developed.The hardware circuit diagram and software flow chart of the board are given,and the function is debugged based on assembly language.The experimental results show its effectiveness.The research work of forward design and software programming of 80C486 processor lays a foundation for repairing the airborne modules with 80C486 controller board,and provides a reference method for the subsequent test and repair of the boards with this type of controller,and provides a new research way for the test method of the same type of controller.
