说明：  本课程设计主要解决用CPLD芯片编程，实现基本模型机中的CPU功能。为方便地址显示灯观测，地址寄存器仍用试验装置上的电路单元，微程序控制器也用实验板上的单元电路提供，CPU的其余各个模块全部写入CPLD中。
(This course is primarily designed to solve using CPLD chip programming, the realization of the basic model of the CPU functional machine. To facilitate the address display lamp observation, the address register is still used on the test device circuit modules, micro-program controller also used the experiment to provide circuit board modules, CPU modules all remaining write in CPLD.)
