1. 单片机的英文

　　MCU introduction
　　Single-chip microcomputer single-chip microcomputer for short, is a typical embedded MCU, abbreviations for commonly used letters of the alphabet MCU microcontroller, it was first used in the field of industrial control. Single chip by chip only has dedicated processors grew out of the CPU. Early design concept through to a large number of peripherals and CPU integrated in a chip, making computer systems more smaller, easier to integrate into the complex and strict with volume control device. 　　INTEL's Z80 processor design is the first in this thought out, and from then on, and dedicated single-chip processor development will go their separate ways. Early is 8-bit or 4-bit single-chip. One of the most successful is INTEL 8,031, good performance because of simple and reliable access to a great deal of praise. After that was developed at 8,031 MCS51 series microcontroller system. Single-chip computer system based on this system now in widespread use. As the field of industrial control requirements grow, beginning a 16-bit microcontroller, but because the price/performance is not satisfactory had not been very widely used. After 90 's with the development of consumer electronics, has been enormous increases in single-chip microcomputer. As INTEL i960 series in particular later ARM series of broad application, rapidly displacing 32-bit single-chip 16-bit single-chip high end position, and move into the mainstream. Traditional 8-bit MCU performance has been the rapid growth of processing power compared to the 80 's increased hundreds of times. At present, high-end 32-bit single-chip clock speed has more than 300MHz, straight after the mid 90 's a dedicated processor, but ordinary model factory price fell to $ 1, top-end models are only $ 10. Contemporary single-chip computer system development and use is no longer only in bare metal environment, large numbers of dedicated embedded operating systems are widely used on the full range of single-chip microcomputer. As handheld and mobile core processing for high-end MCU can even work directly with a dedicated Windows and Linux operating systems.

还有一段看看可以不:
单片机又称单片微控制器,它不是完成某一个逻辑功能的芯片,而是把一个计算机系统集成到一个芯片上。概括的讲：一块芯片就成了一台计算机。它的体积小、质量轻、价格便宜、为学习、应用和开发提供了便利条件。同时，学习使用单片机是了解计算机原理与结构的最佳选择。  单片机内部也用和电脑功能类似的模块，比如CPU，内存，并行总线，还有和硬盘作用相同的存储器件，不同的是它的这些部件性能都相对我们的家用电脑弱很多，不过价钱也是低的，一般不超过10元即可......用它来做一些控制电器一类不是很复杂的工作足矣了。我们现在用的全自动滚筒洗衣机、排烟罩、VCD等等的家电里面都可以看到它的身影！......它主要是作为控制部分的核心部件。   它是一种在线式实时控制计算机，在线式就是现场控制，需要的是有较强的抗干扰能力，较低的成本，这也是和离线式计算机的（比如家用PC）的主要区别。   单片机是靠程序的，并且可以修改。通过不同的程序实现不同的功能，尤其是特殊的独特的一些功能，这是别的器件需要费很大力气才能做到的，有些则是花大力气也很难做到的。一个不是很复杂的功能要是用美国50年代开发的74系列，或者60年代的CD4000系列这些纯硬件来搞定的话，电路一定是一块大PCB板！但是如果要是用美国70年代成功投放市场的系列单片机，结果就会有天壤之别！只因为单片机的通过你编写的程序可以实现高智能，高效率，以及高可靠性！   由于单片机对成本是敏感的，所以目前占统治地位的软件还是最低级汇编语言，它是除了二进制机器码以上最低级的语言了，既然这么低级为什么还要用呢？很多高级的语言已经达到了可视化编程的水平为什么不用呢？原因很简单，就是单片机没有家用计算机那样的CPU，也没有像硬盘那样的海量存储设备。一个可视化高级语言编写的小程序里面即使只有一个按钮，也会达到几十K的尺寸！对于家用PC的硬盘来讲没什么，可是对于单片机来讲是不能接受的。 单片机在硬件资源方面的利用率必须很高才行，所以汇编虽然原始却还是在大量使用。一样的道理，如果把巨型计算机上的操作系统和应用软件拿到家用PC上来运行，家用PC的也是承受不了的。  可以说，二十世纪跨越了三个“电”的时代，即电气时代、电子时代和现已进入的电脑时代。不过，这种电脑，通常是指个人计算机，简称PC机。它由主机、键盘、显示器等组成。还有一类计算机，大多数人却不怎么熟悉。这种计算机就是把智能赋予各种机械的单片机（亦称微控制器）。顾名思义，这种计算机的最小系统只用了一片集成电路，即可进行简单运算和控制。因为它体积小，通常都藏在被控机械的“肚子”里。它在整个装置中，起着有如人类头脑的作用，它出了毛病，整个装置就瘫痪了。现在，这种单片机的使用领域已十分广泛，如智能仪表、实时工控、通讯设备、导航系统、家用电器等。各种产品一旦用上了单片机，就能起到使产品升级换代的功效，常在产品名称前冠以形容词——“智能型”，如智能型洗衣机等。现在有些工厂的技术人员或其它业余电子开发者搞出来的某些产品，不是电路太复杂，就是功能太简单且极易被仿制。究其原因，可能就卡在产品未使用单片机或其它可编程逻辑器件上。 

翻译是工具翻译太多了:Single-chip, also known as single-chip microcontroller, it is not the completion of a logic function of the chip, but a computer system integrated into a chip. Speaking in general terms: a single chip has become a computer. Its small size, light weight, cheap, for the learning, application and development of facilities provided. At the same time, learning to use the principle of single-chip computer to understand and structure the best choice. Single-chip and computer use is also similar to the module, such as CPU, memory, parallel bus, as well as the role and the same hard disk memory, is it different from the performance of these components are relatively weak in our home computer a lot, but the price is low, there is generally no more than 10 yuan ...... can use it to make some control for a class of electrical work is not very complex is sufficient. We are using automatic drum washing machines, smoke hood, VCD and so on inside the home appliances can see it's shadow! ...... It is mainly as part of the core components of the control. It is an online real-time control computer, control-line is at the scene, we need to have a stronger anti-interference ability, low cost, and this is off-line computer (such as home PC) The main difference. By single-chip process, and can be amended. Through different procedures to achieve different functions, in particular the special unique features, this is the need to charge other devices can do a great effort, some of it is also difficult to make great efforts to do so. A function is not very complicated if the United States the development of the 50's series of 74 or 60 during the CD4000 series to get these pure hardware, the circuit must be a big PCB board! However, if the United States if the successful 70's series of single-chip market, the result will be different! Simply because the adoption of single-chip preparation process you can achieve high intelligence, high efficiency and high reliability! Because of the cost of single-chip is sensitive, so the dominant software or the lowest level assembly language, which is in addition to the lowest level for more than binary machine code of the language, since such a low-level so why should we use? Many of the senior's language has reached a level of visual programming Why is it not in use? The reason is simple, that is, single-chip computer as there is no home of CPU, also not as hard as the mass storage device. A visualization of small high-level language program, even if there is only one button which will reach the size of dozens of K! For the home PC's hard drive is nothing, but in terms of the single-chip microcomputer is unacceptable. Single-chip in the utilization of hardware resources have to do very high, so the compilation of the original while still in heavy use. The same token, if the computer giant's operating system and applications run up to get the home PC, home PC can not afford to sustain the same. It can be said that the twentieth century across the three "power" of the times, that is, the electrical era, the electronic age and has now entered the computer age. However, such a computer, usually refers to a personal computer, or PC. It consists of the host, keyboards, displays and other components. There is also a type of computer, not how most people are familiar with. This computer is smart to give a variety of mechanical single-chip (also known as micro-controller). As the name suggests, these computer systems use only the minimum of an integrated circuit to make a simple calculation and control. Because of its small size, are usually charged with possession of machine in the "belly" in. It in the device, like the human mind plays a role, it is wrong, the entire device was paralyzed. Now, this single chip has a very wide field of use, such as smart meters, real-time industrial control, communications equipment, navigation systems, and household appliances. Once a variety of products with the use of the single-chip, will be able to play so that the effectiveness of product upgrading, product names often adjective before the word - "intelligent," such as washing machines and so intelligent. At present, some technical personnel of factories or other amateur electronics developers from engaging in certain products, not the circuit is too complex, that is functional and easy to be too simple imitation. The reason may be the product not on the cards or the use of single-chip programmable logic device on the other.

1. About SCM 
It can be said across the twentieth century, the three "electric" era, that is, electrical era, the electronic age, and has now entered the computer age. However, such a computer, usually refers to the personal computer, referred to as PC. It consists of the host, keyboard, monitor etc.. Another type of computer, most people do not know how. This computer is to smart to give a variety of mechanical microcontroller (also known as micro-controller). As the name suggests, this computer system only used the smallest one IC, you can perform simple operations and control. Because of its small size, usually hidden in a charged mechanical "stomach" Lane. It is the entire device, like the human brain plays a role, it goes wrong, the whole device was paralyzed. 
Now, this MCU has a very wide field of use, such as smart meters, real-time industrial control, communications equipment, navigation systems, home appliances and so on. Once the microcontroller were using a variety of products, you can serve to upgrade the effectiveness of the product, often in the product name is preceded by the adjective - "smart", such as washing machines and so intelligent. At present, some technical personnel of factories or other amateur electronics developers to engage in out of certain products, not the circuit is too complex, that is, functions are too simple and easy to be copied. The reason may be stuck in the product without the use of a microcontroller or other programmable logic device. 
SCM basic component is a central processing unit (CPU in the computing device and controller), read-only memory (usually expressed as a ROM), read-write memory (also known as Random Access Memory MRAM is usually expressed as a RAM) , input / output port (also divided into parallel port and serial port, expressed as I / O port), and so composed. In fact there is also a clock circuit microcontroller, so that during operation and control of the microcontroller, can rhythmic manner. In addition, there are so-called "break system", the system is a "janitor" role, when the microcontroller control object parameters that need to be intervention to reach a particular state, can after this "janitor" communicated to the CPU, so that CPU priorities of the external events to take appropriate counter-measures. 
单片机的简介
可以说，二十世纪跨越了三个“电”的时代，即电气时代、电子时代和现已进入的电脑时代。不过，这种电脑，通常是指个人计算机，简称PC机。它由主机、键盘、显示器等组成。还有一类计算机，大多数人却不怎么熟悉。这种计算机就是把智能赋予各种机械的单片机（亦称微控制器）。顾名思义，这种计算机的最小系统只用了一片集成电路，即可进行简单运算和控制。因为它体积小，通常都藏在被控机械的“肚子”里。它在整个装置中，起着有如人类头脑的作用，它出了毛病，整个装置就瘫痪了。
现在，这种单片机的使用领域已十分广泛，如智能仪表、实时工控、通讯设备、导航系统、家用电器等。各种产品一旦用上了单片机，就能起到使产品升级换代的功效，常在产品名称前冠以形容词——“智能型”，如智能型洗衣机等。现在有些工厂的技术人员或其它业余电子开发者搞出来的某些产品，不是电路太复杂，就是功能太简单且极易被仿制。究其原因，可能就卡在产品未使用单片机或其它可编程逻辑器件上。
单片机的基本组成是由中央处理器（即CPU中的运算器和控制器）、只读存贮器（通常表示为ROM）、读写存贮器（又称随机存贮器通常表示为RAM）、输入/输出口（又分为并行口和串行口，表示为I/O口）等等组成。实际上单片机里面还有一个时钟电路，使单片机在进行运算和控制时，都能有节奏地进行。另外，还有所谓的“中断系统”，这个系统有“传达室”的作用，当单片机控制对象的参数到达某个需要加以干预的状态时，就可经此“传达室”通报给CPU，使CPU根据外部事态的轻重缓急来采取适当的应付措施。
