Even though most of his features in a smallchip, but it has a need to complete the majority of computer components: CPU,memory, internal and external bus system, most will have the Core. At the sametime, such as integrated communication interfaces, timers, real-time clock andother peripheral equipment. And now the most powerful single-chip microcomputersystem can even voice, image, networking, input and output complex systemintegration on a single chip. Also known as single-chip MCU(Microcontroller), because it was first used in the field of industrialcontrol. Only by the single-chip CPU chip developed from the dedicatedprocessor. The design concept is the first by a large number of peripherals andCPU in a single chip, the computer system so that smaller, more easilyintegrated into the complex and demanding on the volume control devices. INTELthe Z80 is one of the first design in accordance with the idea of theprocessor, From then on, the MCU and the development of a dedicated processorparted ways. Early single-chip 8-bit or all of the four.One of the most successful is INTELs 8031, because the performance of a simpleand reliable access to a lot of good praise. Since then in 8031 to develop asingle-chip microcomputer system MCS51 series. Based on single-chipmicrocomputer system of the system is still widely used until now. As the fieldof industrial control requirements increase in the beginning of a 16-bitsingle-chip, but not ideal because the price has not been very widely used.After the 90s with the big consumer electronics product development,single-chip technology is a huge improvement. INTEL i960 Series with subsequentARM in particular, a broad range of applications, quickly replaced by 32-bitsingle-chip 16-bit single-chip high-end status, and enter the mainstreammarket. Traditional
