In recent years, with the computer in the social sector and the development of large-scale integrated circuits, the application of SCM is continuously to thoroughly, because it has the strong function, small volume, low power consumption, low price and reliable, easy to use, so particularly suitable for related control and system, more and more widely used in automatic control, intelligent instrument and meter, data acquisition, military products, and household electrical appliances, etc,As one of the main branch, the single-chip microcomputer in the structure of the biggest characteristic is to put the CPU, memory, and timer RAM and ROM and I/O interface circuit integration on a large scale integrated circuit chip. From its composition and function, a single-chip computer chips actually is.This design is adopted to design the MSC - 51 single-chip four digits calculator, using C language program realization calculator function. External 4X4 keyboard, through the keyboard scan to complete input number of control, use drive circuit make numerical results in the seventh with the normal cathode tube of digital display, and reset button at the finish calculation and display cleared. Calculators will complete the 0-9999 integer with/by a reduction in arithmetic. / /Execution is as follows:Boot is displaying 0, waiting for the type, when the input value, will be displayed by digital tube in input +, -, *, / operator, calculator in internal execution conversion and storage, and waiting for input again, when typing numerical values will type according to the numerical value, will be in equal in digital display operation result.。

In recent years, as computer penetration in the social field and the development of LSI, MCU application is constantly deepening, because of its powerful function, small size, low power consumption, cheap, reliable, easy to use, etc. therefore particularly suitable for control of the system and, more widely used in automatic control, intelligent instruments, instrumentation, data acquisition, and home appliances and other fields. As one of the main branch of microcomputer, microcontroller in the structure of the biggest feature is the CPU, RAM and ROM memory, timer and multiple I / O interface circuit integrated on a VLSI chip. The composition and function from its point of view, a single chip is actually a computer.
This design is the use of MSC-51 Series Microcontroller AT89C51 as the central device in the design of serial communication system. Proteus and Keil structures in the simulation platform to assembly language as a programming language for simulation. System has realized more than serial communication, use of a master-slave, the host sends data, receives data from the machine and displayed under the agreement.

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。
