用单片机实现数字逻辑电路功能.doc

摘　　要 单片机在人类生活中广泛应用 。自从单片机诞生以后，它就步入了人类生活，如洗衣机、电冰箱、电子玩具、收录机等家用电器配上单片机后，提高了智能化程度，增加了功能，倍受人们喜爱。单片机将使人类生活更加方便、舒适、丰富多彩。 综合所述，单片机已成为计算机发展和应用的一个重要方面。另一方面，单片机应用的重要意义还在于，它从根本上改变了传统的控制系统设计思想和设计方法。从前必须由模拟电路或数字电路实现的大部分功能，现在已能用单片机通过软件方法来实现了。这种软件代替硬件的控制技术也称为微控制技术，是传统控制技术的一次革命。 关键词： 广泛 革命 单片机 Summary The single slice machine is extensively applied in the mankinds life.Ever since that time single slice machine after is born, it followed mankind to livingLive, lift after going together with machine up the single slice such as the home applianceses, such as washer, refrigerator, electronics toy and radio/tape recorder...etc.Gao the intelligence turn degree, increased function, doubly is like by people.The single slice machine will make mankind living moreConvenience, comfort, abundant colorful. Comprehensive say, the single slice machine has become a calculator development and applied of aImportant aspect.On the other hand, the single slice important meaning with applied machine still lies in and it by the root changesTraditional control system design thought and design a method.Previously have to from imitate electric circuit or numerical electric circuitThe realization greatly parts of functions have already can pass a software method to carry out with the single slice machine now.This kind of softwareThe control technique which replaces hardware also is called a tiny control technique, is a tradition control is a revolution of technique.
