摘　　要：为设计基于可重构技术的双核微处理器系统,首先实现一个基于微程序控制器的8位微处理器系统(即"实验CPU"),并完成其指令集的设计;而后将"实验CPU"下载至实验平台ARM7-TDMI上,利用实验平台内的可编程资源FPGA构成可重构微处理器;进而将"实验CPU"与实验平台内的ARM CPU构成双核微处理器系统,最后对双核微处理器系统的工作方式和体系结构进行了初步研究。研究结果显示:该微处理器系统简单灵活,更可靠和实用,还可将外部信号引入,并进行分析处理。In order to design a dual kernel microprocessor system based on FPGA, the first step is to build an 8 bit micro-programmed control'experimental CPU' and to design an instruction system. After that, the 'experimental CPU' is downloaded into an ARM7-TDMI platform, within whichFPGA, a kind of programmable resource, is used to constitute a reconfigurable processor. Then, the 'experimental CPU' and the ARM CPU withinexperimental platform are built into a duo kernel CPU system. When the design completed, analyses have been undertaken with respect to the work modeand architecture structure of the duo kernel system. The result shows that compared with traditional approaches, the duo kernel processor is simpler, moreflexible, more reliable and more practicable; the processor can also analyze and process input signals if equipped with appropriated peripheral equipments.
