SCM-MCU-SoC单片机的发展历史（国外英文资料） The development history of SCM - MCU - SoC single-chip microcomputer was forwarded to the article at 22:50 on Sunday, 005, 2010, to discuss the development history of the single chip machine. SCM definition: A single chip is a complete computer system integrated on a chip. Although most of his functional integration on a small chip, but it has a complete computer need most of the parts: CPU, memory, internal and external bus system, most will have a CRT. It also integrates peripherals such as communication interfaces, timers, and real-time clocks. Now the most powerful single chip system can even integrate sound, images, networks, and complex input and output systems onto a single chip. Single chip, also known as micro-controller (Microcontroller), it is not complete a certain logic function of chips, but to a computer system integrated into a chip. In a nutshell: a chip is a computer. Its small size, light quality, cheap price and convenient conditions for learning, application and development. At the same time, learning to use a single chip is the best choice for understanding computer principles and structures. Computer history: The single chip machine was born in the late 1970s and experienced the three stages of SCM, MCU, and SoC. SCM is the Single ChipMicrocomputer phase, which is the best architecture for finding the best monolithic embedded system. The success of the innovation model laid a different path for the SCM and the general computer. Intel has been instrumental in creating an independent development path for embedded systems. 2. The MCU, the Micro controller (Micro ControllerUnit) phase, the main technological development direction is: expanding to meet embedded application, the object system requirements of various peripheral circuit and interface circuit, highlight its intelligent control of objects. The areas involved are related to the object system, so the task of developing MCU inevitably falls to the electronics an
