The design of a high performance and low power embedded microprocessor core OM80C51

OM80C51 is an embedded microprocessor core compatible with 80C51. But some of its performances are better than those of 80C51. For instance, it has shorter instruction cycles for most instructions, a more efficient power management system, and a customizable interrupt system and periphery circuits, with an area of about 7500 gates. All of the above make it attractive for embedded system applications. Many of these attainments can attribute to the divide-and-conquer methodology used in the design of OM80C51. It has been verified by FPGA.
