【正文】 After the air conditioner uses the monolithic integrated circuit, not only the remote control parameter establishment is convenient, the running status transforms automatically, but may also realize the frequency conversion control. After at present many domestic electric appliances like VCD, DVD only then the monolithic integrated circuit appears, only then possibly realizes its function. 3. The embedded system has led entire electronic industry the present electron primary device industry besides the microprocessor, the embedded system ponent, mostly is revolves the modern electron systems assembly the primary device industry, for example satisfies the pressed key which the manmachine interaction uses, LED/LCD demonstrated that the actuation, the LED/LCD display unit, the pronunciation integrated device and so on, satisfies the data acquisition channel request the digital sensor, ADC, the data acquisition module, the signal recuperation module and so on, satisfies the servo to actuate the control DAC, the solid relay, to stepbystep electrical machinery controller, the frequency 33 conversion control unit and so on, satisfies the correspondence request each kind of main line driver, the level switch and so on. world electron primary device under the embedded syst。s absolute form and the function. The monolithic integrated circuit is pletely defers to the embedded system request design, therefore the monolithic integrated circuit is the most typical embedded system. The early monolithic integrated circuit is only according to the embedded applied technology request design puter single chip integration, therefore famous monolithic integrated circuit. Afterward, the monolithic integrated circuit to satisfy embedded strengthens its control function and the periphery interface function unceasingly using the request, particularly prominent control function, therefore internationally rectified names the monolithic integrated circuit for the micro controller (MCU, Microcontroller Unit). the 2. Monolithic integrated circuit constitutes the modern electron system will bee mainstream electron system the monolithic integrated circuit will be the ponent level puter system, it may insert to any object system, realizes the intellectualized control. Slightly 32 to miniature machinery, like wristwatch, hearing aid. The integrated device level39。 autopilot, turbine observation system and so on. The embedded system first is a puter system, next it is inserted to the object system, realizes in the object system object functions and so on request data acquisition, processing, condition demonstration, output control, because inserts in the object system, embedded system39。s embedded application, the early embedded system for the generalpurpose calculator after the reequipping inserts to the object system39。s principle), needs plex being similar in puter39。s is also quite widespread in medical equipment domain application the in medical equipment use, for example medical lifesupport machine, each kind of analyzer, guardianship meter, ultrasound diagnosis equipment and hospital bed ringing system and so on. 6. Certain specialpurpose monolithic integrated circuit design uses in each kind of largescale electric appliance39。s munication facility has basically realized the monolithic integrated circuit intelligent control, from the handset, the telephone, the small program controlled switch, the building automatic correspondence ringing system, the train wireless munication, arrived at the mobile phone which again in the routine work found at everywhere, the colony mobile munication, radio inter and so on. 5. Monolithic integrated circuit39。s application the , may carry on the data munication very conveniently with the puter, for provided the extremely good 30 physical conditions application between the puter work and munication facility39。 application , present39。s sensor, may realize such as physical quantity and so on voltage, power, frequency, humidity, temperature, current capacity, speed, thickness, angle, length, degree of hardness, element, pressure surveys. Uses the monolithic integrated circuit control to cause the instruments and meters digitization, the intellectualization, the microminiaturization, and the function pares uses the electron or the digital circuit is more formidable. For example precise measurement equipment (dynamometer, oscilloscope, each kind of analyzer). 2. May constitute various control system, the data acquisition system in industrial control39。s intellectualized management and process control, approximately separable following several categories: 1. Monolithic integrated circuit has the volume on smart instrument measuring appliance39。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 each kind of intelligent IC card, the civil luxury car39。s work munication and the data transmission, the industrial automation process39。s navigation equipment, on the airplane each kind of measuring appliance39。s application domain At 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 28 development has formed the SOC tendency naturally. Along with the microelectronic technology, the IC design, the EDA tool39。s on chip maximized solution。s road of independent development, to the MCU stage development39。s best architecture. “the innovation pattern” obtains successfully, h as established SCM and the generalpurpose calculator pletely different development path.
