The architecture comparison and the VLSI implementation of the 32 bit embedded RISC

In order to achieve our design goal as a low-cost and high-performance microprocessor, we compared several aspects of the popular embedded RISC architecture, such as general-purpose register file and stack-based, three-stages pipeline and five-stages one, Von Neumman architecture and Harvard counterpart, etc. By these comparisons, we adopted the most suitable architecture sets: a Harvard five-stages pipeline with a set of general-purpose register file. We also verified our design on the Aptix System Explorer MP3CF hardware verification platform and implemented on CSMC 0.6 mm CMOS process.
