INTELs Z80 is the first designed in accordance with this idea processor, then on the development of microcontroller and dedicated processors have parted way

3、s.Are 8-bit microcontroller early or 4 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 MCS51 MCU Systems. SCM systems based on this system until now is still widely used. With the increased requirement

4、s 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 consumer electronics, microcontroller technology has been a huge increase. With INTEL i960 series, especially the later

5、 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 the rapid increase capacity increase compared to 80 the number of times. Currently, high-end 32-bit microcontroll

6、er 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 SCM systems are no longer only in the development and use of bare metal environment, a large number of propriet

Modern human life used in almost every piece of electronic and mechanical products will be integrated single chip. Phone, telephone, calculator, home appliances, electronic toys, handheld computers and computer a

9、ccessories 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 control systems may even have hundreds of SCM in the same time work! SCM is not only far exceeds the number of PC

10、and other computing the sum, or even more than the number of human beingsSingle chip, also known as single-chip microcontroller, it is not complete a certain logic chips, but to a computer system integrated into a chip. Equivalent to a micro-computer, and computer than just the lack of a microcontro

At the same time, learning to use the MCU is to understand the principle and structure of the computer the best choice.SCM and the comp

12、uter 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 components were relatively weak many of our home computer, but the price is low , usually not more than 10 yuan you can

13、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 see its shadow! . It is primarily as a control section of the core componentsIt is an online real-time control com

14、puter, 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 chipMCU is through running, and can be modified. Through different procedures to achieve different functions, in particular s

15、pecial 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 developed 74 series, or the 60s CD4000 series of these pure hardware buttoned, then the circuit must be a large PCB

16、 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 th

17、e dominant software or the lowest level assembly language, which is the lowest level in addition to more than binary machine code language, and as so low why is the use? Many high-level language has reached the level of visual programming Why is not it? The reason is simply that there is no home com

18、puter as a single chip CPU, not as hard as a mass storage device. A visualization of small high-level language program which even if only one button, will reach tens of K of size! For the home PCs hard drive in terms of nothing, but in terms of the MCU is not acceptable. SCM in the utilization of ha
