【正文】 隨著微電子技術(shù)、IC設(shè)計(jì)、EDA工具的發(fā)展。因此，當(dāng)我們回顧嵌入式系統(tǒng)發(fā)展道路時(shí)，不要忘記Intel和Philips的歷史功績。在發(fā)展MCU方面，最著名的廠家當(dāng)數(shù)Philips公司。它所涉及的領(lǐng)域都與對(duì)象系統(tǒng)相關(guān)，因此，發(fā)展MCU的重任不可避免地落在電氣、電子技術(shù)廠家。在開創(chuàng)嵌入式系統(tǒng)獨(dú)立發(fā)展道路上，Intel公司功不可沒。（Single Chip Microputer）階段，主要是尋求最佳的單片形態(tài)嵌入式系統(tǒng)的最佳體系結(jié)構(gòu)。s best paths.The monolithic integrated circuit leads you to enter most charming electronic world the alone charm the monolithic function to cause you to realize puter39。s internal software and hardware system, can prehend puter39。s intelligence changes into the without limits boundary, does not need the hardware source the addition to be able frequently to realize each kind to renovate the function. This is also one of current many domestic electric appliances function massive addition factors.The monolithic integrated circuit leads you to enter calculates the mechanic to control domain in the 21st century is the universe enters Computer Age the century, many people are not are making the puter are using the puter. In uses in puter39。s application procedure entrusts with it “the life”. For example, when design intellectualization instrument monitor39。s broad road as soon as possible.The monolithic integrated circuit will acplish the new generation electron outstanding personIf the 50s, the radio world has acplished several generation of outstanding people, then the now monolithic integrated circuit world will acplish the new generation electron outstanding person.The monolithic integrated circuit leads you to enter intellectualized electron domain, if treats as the classical electron system a deathly stiff electronic system, then the intellectualized modern electron system has “the life” the electronic system. The monolithic integrated circuit application system39。s world to be getting more and smaller. In the electronic system39。s low end, lowers to several Yuan, several Yuan, causes the monolithic integrated circuit to popularize sufficiently to many civil electrical appliances, the electronic toy. The monolithic integrated circuit constitutes the modern electron system penetrated into various each household, is changing our life, like in family sound, television, washer, microwave oven, telephone, burglary protection system, air conditioner and so on. The monolithic integrated circuit innovated the original electronic system, after like the microwave oven uses the monolithic integrated circuit control, but carries on the clock establishment, the procedure memory, the power control conveniently。s puter does not have puter39。s in each kind of electronic system, like ships39。s principle. For example: Music signal saves by the digital form in the memory (is similar to ROM), reads out by the micro controller, transforms (is similar for the simulation music electrical signal to sound card). in the largescale electric circuit, this kind of modular application reduced the volume enormously, simplified the electric circuit, reduced the damage, the error rate, also facilitates in the replacement. in addition, the monolithic integrated circuit in the industry and merce, the finance, the scientific research, the education, domains and so on national defense aerospace has the very widespread use.The monolithic integrated circuit founded the modern electron system timeThe monolithic integrated circuit and embedded system the embedded system stems from puter39。s modulation using the realizing the specific function, thus carries on the modular application in each kind of electric circuit, but does not request to use the personnel to understand its internal structure. If music integration monolithic integrated circuit, looked that resembles the simple function, micro shrinks in the pure electronic chip (is different with magnetic tape unit39。s monolithic integrated circuit39。s, present39。s domestic electric appliances basically have used the monolithic integrated circuit control, praises, the washer, the electric refrigerator, the air conditioner, the color television, other acoustic video frequency equipment from the electricity food, to arrive at the electronic weighting equipment again, all kinds of gate, omnipresent. Modern of monolithic integrated circuit has the correspondence connection generally in the puter network and correspondence domain39。s application with the monolithic integrated circuit. For example factory assembly line intellectualized management, elevator intellectualization control, each kind of alarm system, with puter networking constitution twostage control system and so on. May say like this in domestic electric appliances39。s application the to be small, the power loss is low, the control function is strong, the expansion is flexible, merits and so on microminiaturization and easy to operate, widely apply in the instruments and meters, the union different type39。s study, the development and the application will acplish one batch of puter application and the intellectualized control scientist, engineer. The monolithic integrated circuit widely applies in the instruments and meters, the domestic electric appliances, the medical equipment, domains and so on aerospace, special purpose equipment39。s safety system, the videocorder, the camera, the pletely automatic washer39。s realtime control and the data processing, the widespread use39。s control, puter39。s trail. Missile39。s development, can have the big development based on the SOC monolithic integrated circuit application system design. Therefore, to the monolithic integrated circuit the understanding may from the monolithic microputer, the monolithic micro controller extend to the monolithic application system.Monolithic integrated circuit39。 Therefore, the specialpurpose monolithic integrated circuit39。s important attribute, seeks application system39。s each kind of peripheral circuit and the interface circuit, underline its object intellectualization control. It involves the domain is related with the object system, therefore, develops the MCU heavy responsibility to fall inevitably on electric
