1、外文文献及翻译河南理工大学万方科技学院电气与自动化工程系2013届毕业生英文文献专业： 电子信息工程 班级： 电信09-2班 学号： 0916302010 姓名： 韩珍珍 外文资料与中文翻译外文资料：The Introduce Of Single Chip Microcomputer SCM is also known as micro-controller (Microcontroller Unit), commonly used letters of the acronym MCU that it was first used in industrial control. Only a s

2、ingle chip by the CPU chip developed from a dedicated processor. The first design is by a large number of peripherals and CPU on a chip in the computer system, smaller, more easily integrated into a complex and demanding on the volume control device which. INTELsZ80 is the first designed in accordan

3、ce with this idea processor, then on the development of microcontroller and dedicated processors have parted ways. Are 8-bit microcontroller early or4 bits. One of the most successful is the INTEL 8031, for a simple, reliable and good performance was a lot of praise. Then developed in 8031 out of MC

4、S51 MCU Systems. SCM systems based on this system until now is still widely used. With the increased requirements of industrial control field, began a 16-bit microcontroller, because the cost is not satisfactory but have not been very widely used. After 90 years with the great development of consume

5、r electronics, microcontroller technology has been a huge increase. With INTEL i960 series, especially the later series of widely used ARM, 32-bit microcontroller quickly replace high-end 16-bit MCU status and enter the mainstream market. The traditional 8-bit microcontroller performance have been t

6、he rapid increase capacity increase compared to 80 the number of times. Currently, high-end 32-bit microcontroller clocked over 300MHz, the performance catching the mid-90s dedicated processor, while the average model prices fall to one U.S. dollars, the most high-end 1 model only 10 dollars.Modern

7、SCM systems are no longer only in the development and use of bare metal environment, a large number of proprietary embedded operating system is widely used in the full range of SCM. The handheld computers and cell phones as the core processing of high-end microcontroller can even use a dedicated Win

8、dows and Linux operating systems. SCM is more suitable than the specific processor used in embedded systems, so it was up to the application. In fact the number of SCM is the worlds largest computer. Modern human life used in almost every piece of electronic and mechanical products will be integrate

9、d single chip.Phone, telephone, calculator, home appliances, electronic toys, handheld computers and computer accessories such as a mouse with a 1-2 in both the Department of SCM. Personal computer will have a large number of SCM in the work. General car with more than 40 SCM, complex industrial con

10、trol systems may even have hundreds of SCM in the same time work! SCM is not only far exceeds the number of PC and other computing the sum, or even more than the number of human beings Single chip, also known as single-chip microcontroller, it is not complete a certain logic chips, but to a computer

11、 system integrated into a chip.Equivalent to a micro-computer, and computer than just the lack of a microcontroller I / O devices. General talk: a chip becomes a computer. Its small size, light weight, cheap, for the study, application and development of facilities provided. At the same time, learni

12、ng to use the MCU is to understand the principle and structure of the computer the best choice. SCM and the computer functions internally with similar modules, such as CPU, memory, parallel bus, the same effect as well, and hard disk memory devices, and different is its performance of these componen

13、ts were relatively weak many of our home computer, but the price is low , usually not more than 10 yuan you can do with it . some control for a class is not very complicated electrical work is enough of. We are using automatic drum washing machine, smoke hood, VCD and so on appliances which could se

14、e its shadow! . It is primarily as a control section of the core components It is an online real-time control computer, control-line is that the scene is needed is a stronger anti-jamming ability, low cost, and this is, and off-line computer (such as home PC), the main difference. Single chip MCU is

15、 through running, and can be modified. Through different procedures to achieve different functions, in particular special unique features, this is another device much effort needs to be done, some great efforts are very difficult to do. A not very complex functions if the 50s with the United States

16、developed 74 series, or the 60s CD4000 series of these pure hardware buttoned, then the circuit must be a large PCB board! But if the United States if the 70s with a series of successful SCM market, the result will be a drastic change! Just because you are prepared by microcomputer programs can achieve high intelligence, high efficiency and high reliability!As the microcontroller on the cost-sensitive, so now the dominant sof
