通过对计算机的组织与结构的分析，综合运用所学计算机原理知识，设计并实现较为完整的计算机，即模型机。它可以完成一般计算机的最基础功能，具备16条基本指令，以及4种寻址方式等。并且，计算机数据通路的控制将由微程序控制器来完成，CPU从内存中取出一条机器指令到指令执行结束的一个指令周期全部由微指令组成的序列来完成，即一条机器指令对应一个微程序。设计过程包括四个部分：㈠模型机硬件组成分析；㈡指令系统设计；㈢微程序设计；㈣上机实现，示范程序。- Through to the computer organization and the structure analysis, the synthesis utilization studies the computer principle knowledge, designs and realizes a more complete computer, namely molding machine. It may complete the common computer the most foundation function, has 16 elementary instructions, as well as 4 addressing ways and so on. And, the computer data path control will complete by the microprogram controller, CPU will take out a machine instruction from the memory a instruction cycle which finished to the instruction execution completely the sequence which will be composed by the microcode to complete, namely a machine instruction will correspond a microprogram. Design process including four parts: (1) Molding machine hardware composition analysis;
