單片機的原理 The principle of SCM(中文2800字,英文2000字)
單片機是一個完整的計算機系統集成在芯片上。盡管他的大部分功能集成在一個小芯片,但它有一個完整的計算機最需要的部分:CPU、內存、內部和外部總線系統,大多數CRT。同時集成、通信接口、定時器,實時時鐘等外圍設備,F在最強大的單片機系統甚至可以聲音、圖像、網絡、復雜的輸入輸出系統集成在一個芯片上。單芯片,也被稱為微控制器,因為這是第一次使用在工業控制領域。單片機只有CPU芯片專用處理器。最早的設計理念是通過大量的外設和CPU的集成芯片,使計算機系統更小、更容易地集成到一個更復雜的和嚴格的控制設備。英特爾Z80根據這個想法是最早的處理器設計,從那時起,單片機和專用處理器的發展會分道揚鑣。早期單片機8或4。最成功的是英特爾的8031,因為簡單、可靠、性能良好的贊譽。自8031年開發了MCS51系列單片機系統;谙到y的單片機系統直到現在還在廣泛使用。隨著工業控制領域的改善,開始了16位單片機,但因為性價比不理想并未廣泛使用。90年代后隨著消費電子產品開發,單片機技術得到了巨大的改善。作為英特爾i960系列尤其是后臂系列廣泛應用,32位單片機迅速取代高端地位,16位單片機和進入主流市場。

The principle of SCM
   SCM is a complete computer systems integration 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.At the same time integration, such as the communication interface, timer, real-time clock and other peripheral equipment.Now the most powerful single-chip microcomputer system can even voice, image, network, complex input/output system integration on a chip.Single chip, also known as micro controller, because it was first used in the field of industrial control.Single chip microcomputer by only CPU chip dedicated processors.Is the earliest design concept through the integration of a large number of peripherals and CPU in a chip, make the computer system smaller, more easily integrated into a more intricate and strict in volume control equipment.INTEL Z80 is the earliest according to this idea processor design, from then on, the development of microcontroller and dedicated processors will go their separate
