SCM namely monolithic microputer (Single Chip Microputer) the stage, mainly seeks the best monolithic shape embedded system39。s best architecture. “the innovation pattern” obtains successfully, has established SCM and the generalpurpose calculator pletely different development path. In founds on the embedded system independent development path, Intel Corporation has lasting achievements. 2. MCU namely micro controller (Micro Controller Unit) the stage, the main technological development direction is: Expands unceasingly when satisfies the embedded application, the object system request39。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 electrical, the electronic technology factory. Looking from this angle, Intel fades out the MCU development also to have its objective factor gradually. Is developing the MCU aspect, the most famous factory family belongings count Philips Corporation. Philips Corporation by it in embedded application aspect huge superiority, MCS51 from monolithic microputer rapidly expand to micro controller. Therefore, when we review the embedded system development path, do not forget Intel and the Philips historical merit. 3. Monolithic integrated circuit is the embedded system39。s road of independent development, to the MCU stage development39。s important attribute, seeks application system39。s on chip maximized solution。 Therefore, the specialpurpose monolithic integrated circuit39。s development has formed the SOC tendency naturally. Along with the microelectronic technology, the IC design, the EDA tool39。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。s application domainAt present the monolithic integrated circuit seeps each domain which lives to us, which domain was nearly very difficult to find not to have monolithic integrated circuit39。s trail. Missile39。s navigation equipment, on the airplane each kind of measuring appliance39。s control, puter39。s network munication and the data transmission, the industrial automation process39。s realtime control and the data processing, the widespread use39。s each kind of intelligent IC card, the civil luxury car39。s safety system, the videocorder, the camera, the pletely automatic washer39。s control, as well as program control toy, electronic pet and so on, these cannot leave the monolithic integrated circuit. Say nothing of automatic control domain robot, intelligent measuring appliance, medical instrument. Therefore, monolithic integrated circuit39。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 intellectualized manage
