【正文】 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 puters and cell phones as the core processing of highend microcontroller can even use a dedicated Windows 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 world39。通信工程學(xué)院 畢業(yè)設(shè)計外文翻譯 畢業(yè)設(shè)計題目 超市小件物品寄存控制系統(tǒng)設(shè)計 外 文 題 目 Supertmarket storage of small items control systerm 專業(yè)：信息工程 學(xué)號： 20221218 學(xué)生姓名： 魯彥超 指導(dǎo)教師姓名： 指導(dǎo)教師職稱： 日期： 2022 年 11 月 20 日 The Introduce Of Single Chip Microputer SCM is also known as microcontroller (Microcontroller Unit), monly used letters of the acronym MCU that it was first used in industrial control. Only a single 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 puter system, smaller, more easily integrated into a plex and demanding on the volume control device which. INTEL39。sZ80 is the first designed in accordance with this idea processor, then on the development of microcontroller and dedicated processors have parted ways. Are 8bit 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 MCS51 MCU Systems. SCM systems based on this system until now is still widely used. With the increased requirements of industrial control field, began a 16bit 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 series of widely used ARM, 32bit microcontroller quickly replace highend 16bit MCU status and enter the mainstream market. The traditional 8bit microcontroller performance have been the rapid increase capacity increase pared to 80 the number of times. Currently, highend 32bit microcontroller clocked over 300MHz, the performance catching the mid9039。s largest puter. Modern human life used in almost every piece of electronic and mechanical products will be integrated single , telephone, calculator, home appliances, electronic toys, handheld puters and puter accessories such as a mouse with a 12 in both the Department of SCM. Personal puter will have a large number of SCM in the work. General car with more than 40 SCM, plex industrial control systems may even have hundreds of SCM in the same time work! SCM is not only far exceeds the number of PC and other puting the sum, or even more than the number of human beings Single chip, also known as singlechip microcontroller, it is not plete a certain logic chips, but to a puter system integrated into a to a microputer, and puter than just the lack of a microcontroller I / O devices. General talk: a chip bees a puter. Its small size, light weight, cheap, for the study, application and development of facilities provided. At the same time, learning to use the MCU is to understand the principle and structure of the puter the best choice. SCM and the puter 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 ponents were relatively weak m
