The Design Of MPU And Its Improved Chip Based On Reverse Engineering

Microprocessor Unit(MPU) is not only the core of the integrated circuit (IC), but also the"heart"of the information technology, the research and design of the MPU is a matter of the utmost economic and political importance. The research and design of the MPU is an extremely complicated work, is suffering from many technical difficult problems. Although some microprocessor chips which have higher bits and higher performances have been developed in our country, they still have a certain distance from the market, on the contrary, some lower-bit microprocessor chips are able to compete with similar products in the market, and they can produce a profit for the corresponding companies. The purpose of our paper is to design 8-bits MPU which have good capacity of competition in the market, also to lie the groundwork for the future design of higher-bits MPU, because no matter how many bits of the MPU have, the design technique and the principle of the MPU is the same. We designed two kinds of MPU in our paper, they are:(1) An 8-bits general MPU, it is compared with other MPU which have good market share, the result shows that our MPU have better performance, and it will have a very profitable market.(2)By improving the general MPU, we designed a high-performance and low-power 8-bits embedded MPU which is used widely in portable application. In the same time, laid the good groundwork for the future design of higher-bits embedded MPU, because in the higher-bits embedded application, embedded MPU will at the helm of the applications. In order to make our design more attractive, we lucubrated the principle of MPU. In the design, we not only put theory and techniques...
