摘　　要：微程序控制器主要是用于微指令排序和微指令执行。文章详细介绍了龙腾“C1”微处理器中微控器的体系结构,以高性能为目标,对微控器的预取部件进行了优化设计,并设计了微指令格式,同时在微控器中还采用了流水技术来优化设计。通过仿真结果表明系统性能得到提高,执行速度得到加快,达到了预期目的。The Microprogrammed Contrel Unit （MCU） is mainly used to the ordering and obeys of microinstruction. This text is detailed to introduce the archecture of the Longtium C1 microprocessor＇s Microprogrammed Control Unit, taking high performance as the target carried on the optimization design to the predicted unit of the MCU. The optimization design of the microinstruction format is designed and the technique of pipeline is adopted in the MCU design. It＇s indicated that the system performance and the executive speed have been improved than ever through the result of simulation. And the result of simulation shows that the design is achieve our expectant purpose.
