In the electronic field, especially automation intelligent control field, the traditional division ponents or digital logic circuit consists of the control system is unprecedented speed is single chip microputer intelligent control system is replaced. SCM has small, strong function, the cost is low, the wide application advantages, such as, say, intelligent control and automatic control is the core of the single chip microputer. At present, a study and application of the climax of the single chip microputer is factory, schools and enterprises and institutions rise on a large scale. The past used to traditional electronic fields of engineers, technicians are faced with new challenges, such as not in a relatively short period of time to learn a singlechip microputer, certainly will will be thrown up by age, only brave to face reality, challenge ourselves, strengthen learning, for in a relatively short time will of single chip microputer mastery, to keep up with the pace of The Times. It brings convenience is not negative, it on a chip integrated within the functions of puter parts, constitute a kind of single chip microputer. Since the 1980 s, the international on MCU development rapidly, its product of dazzling, SCM unceasingly thorough, new technology are endless. The 20 th century, electronic technology has experienced rapid growth in its promotion, modern electronic product almost permeated every area of society a powerful impetus to the development of the social productive forces and the enhancement of social informatization, and at the same time, make modern electronic products to further improve the performance, product update rhythm also more and more quickly. This design is by microputer simulation calculator, it can not only realize the data add, subtract, multiply and divide operation, and still can make the data and results in digital tube displayed, will be able to realize the 0256 digital arithmetic. This design is AT89C51 single chip microputer to control with, of all the
