1、原文来源 图书馆电子资源 Single chip brief introductionThe monolithic integrated circuit said that the monolithic micro controller, it is not completes some logical function the chip, but integrates a computer system to a chip on. Summary speaking: A chip has become a computer. Its volume is small, the quality
2、is light, and the price cheap, for the study, the application and the development has provided the convenient condition. At the same time, the study use monolithic integrated circuit is understands the computer principle and the structure best choice.The monolithic integrated circuit interior also u

Realizes the different function through the different procedure, particularly special unique some functions, this is other component needs to take the very big effort to be able to achieve, some are the flowered big strength is also very difficult to achieve.

But if, if succeeded in the 70s with the US puts in the market the series monolithic integrated circuit, the re

Because only the monolithic integrated circuit compiles through you the procedure may realize the high intelligence, high efficiency, as well as redundant reliability The CPU is the key component of a digital computer. Its purpose is to decode instruction received
9、 from memory and perform transfers, arithmetic, logic, and control operations with data stored in internal registers, memory, or I/O interface units. Externally, the CPU provides one or more buses for transferring instructions, data, and control information to and from components connected to it. A
10、microcontroller is present in the keyboard and in the monitor in the generic computer; thus these components are also shaded. In such microcontrollers, the CPU may be quite different from those discussed in this chapter. The word lengths may be short, the number of registers small, and the instructi
11、on sets limited. Performance, relatively speaking, is poor, but adequate for the task. Most important, the cost of these microcontrollers is very low, making their use cost effective. Because the monolithic integrated circuit to the cost is sensitive, therefore present occupies the dominant status t
12、he software is the most preliminary assembly language7 it was except the binary machine code above the most preliminary language, since why were such preliminary must use? Why high-level did the language already achieve the visualization programming level not to use? The reason is very simple, is th

Inside even if a visualization higher order language compilation script only then a button, also will achieve several dozens K the sizes! Does not speak anythi

It can be said that the 20th century surmounted three the electricity the time, namely the electrical time, the Electronic Age and already entered computer time. H
16、owever, this kind of computer, usually refers to the personal computer, is called PC machine. It by the main engine, the keyboard, the monitor and so on is composed. Also has a kind of computer, most people actually not how familiar. This kind of computer is entrusts with the intelligence each kind

Because its volume is small, usually hides in is accused the m

24、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农机、排烟罩、VCD等等的家电里面都可以看到它的身影！它主要是作为控制局部的核心部件。 它是一种存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，较低的本钱，这也是和离线式计算机的比方家用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多人力气才能做到的，有些那么是花人力气也很难做到的。一个不是很复杂的功能要是用美同50年代开发的74系列，或者60年代
25、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科能，高效率，以及高可靠性！ CPU(中央处理单元)是数字计算机的重要组成局部，其目的是对从内存中接收的指令进行译码，同时对存储于内部存放器、存储器或输入输出接口单元的数据惊醒传输、算术运算、逻辑运算以及控制运算。在外部，CPU位转换指令数据和控制信息提供一个或多个总线并从组件连接到它。一个微控制器出现在普通电脑的键盘和检测器中，但是这些组件也被屏蔽。在这种微控制器中，与我们所讨论的CPU可能不同。字长也许更短，编制数
26、量少，指令集有限。相对而言，性能差，但对完成任务来说足够了。最重要的是它的微控制器的本钱很低，符合本钱效应。 由于单片机对本钱是敏感的，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到达了可视化编程的水平为什么不用呢？原因简单，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，也会到达几十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
27、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。它白主机、键盘、显示器等组成。还有一类计算机，人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，如科能仪表、实时T控、通讯设备
28、、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成效，常在产品名称前冠以形容词一一“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 外文翻译 外文文献 英文文献 单片机简介 中英对照原文来源 图书馆电子资源 Single chip brief introductionThe monolithic integrated circuit said that the monolithic micro controller, it is not completes some logical function the chip, but integrates a computer system to a chip滇皋究鹊沮油镐农限亮直注豢醉荆迹湛粗蔬澈杠裁典应昼邢筛裹舜荆借牙获聂赛阔前道篡又流盂疙库超犹讥帐襄不服笼解酝傣咬缄侨叶次骂邢代幸
