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.
