Abstract: The design method and process of a MPU which is compatible with MCS 8051 in instruction set are illustrated in the paper. The up to down structure d esign method is adopted. VHDL language is employed to design and simulate the MP U chip. The chip is divided into many units, lastly the VHDL design is synth esi zed into a logic netlist. The VHDL structure design method, verification wit h FP GA and the design of controller with VHDL are introduced in detail in the p aper.

摘要： 介绍了设计与MCS8051微处理器指令集完全兼容的微处理器芯片的方法和过程。 设计中采用自上而下的结构化设计方法。利用VHDL语言对目标芯片进行描述仿真，逐步细化 ，最后综合成逻辑级的网表。该文中重点介绍了VHDL结构化层次设计、FPGA验证以及在RTL 级利用VHDL语言对控制器单元的设计。
