best meet environmental requirements, for example, chiplevel physical space, largescale integrated circuits lowcost, good peripheral interface bus and outstanding control of instruction. A puter system microcontroller core, embedded electronic systems, intelligent electronic systems for the foundation. Therefore, the current single chip electronic system in widespread use of electronic systems to enable rapid transition to the classical modern intelligent electronic systems. 4, single chip to create the modern era of electronic systems 1 A microcontroller and embedded Systems Embedded puter systems from embedded applications, embedded systems for early generalpurpose puter adapted to the object system embedded in a variety of electronic systems, such as the ship39。 s autopilot, engine monitoring systems. Embedded system is primarily a puter system, followed by it being embedded into the object system, objects in the object system to achieve required data collection, processing, status display, the output control functions, as embedded in the object system, embedded system puter does not have an independent form and function of the puter. SCM is entirely in accordance with the requirements of embedded system design, so SCM is the most typical embedded systems. SCM is the early application of technical requirements in accordance with the design of embedded puter chip integration, hence the name single chip. Subsequently, the MCU embedded applications to meet the growing demands of its control functions and peripheral interface functions, in particular, highlight the control function, so has international name the single chip microcontroller (MCU, Microcontroller Unit). 2 MCU modern electronic systems consisting of electronic systems will bee mainstream MCU is a devicelevel puter systems, it can be embedded into any object system to achieve intelligent control. Small to micromachinery, such as watches, hearing aids. Lowcost integrated devicelevel, lowto a few dollars, ten dollars, enough to spread to many civilian SCM appliances, electronic toys to go. SCM constitutes a modern electronic systems has indepth to the households, are changing our lives, such as home audio, televisions, washing machines, microwave ovens, telephones, security systems, and air conditioners. SCM innovation the original electronic systems, such as microwave ovens use SCM, it can easily set the clock, the program memory, power control。 air conditioner after use of SCM is not only convenient for remote parameter setting, running automatically transform, frequency control can be achieved. At present, many household appliances such as VCD, DVD only single chip to achieve its function may occur before. 3 Embedded Systems led the entire electronics industry Current electronic ponents industry, in addition to microprocessors, embedded system devices, the most modern electronic systems around the supporting ponents industries, such as keys used to meet the humanputer interaction, LED / LCD display drivers, LED / LCD display units, voice integrated device, etc., to meet the requirements of data acquisition channel digital sensor, ADC, data acquisition module, signal conditioning modules to meet the servo drive control in the DAC, solid state relays, stepper motor controller, frequency control unit, etc., to meet the munication requirements various bus driver, level converters. Electronic ponents in the embedded systems world, driven by embedded applications along fully meet requirements of modern electronic systems makes the original classic world of increasingly small electronic systems. Practitioners in the var。
