Even though most of his features at a small chip on, but it has a plete puter most of the necessary ponents: CPU, memory, internal and external bus system, most will have the Core. At the same time, such as integrated munication interfaces, timers, realtime clock and other peripheral equipment. And now the most powerful singlechip microputer system can even voice, image, network, plex input and output of system integration on a single chip.Also known as singlechip MCU (Microcontroller), because it is the first to be used in the field of industrial control. Singlechip by chip dedicated processor CPU only evolved. The first design concept through to a large number of peripherals and CPU in a single chip, the puter system so that smaller, more easily integrated into the plex and demanding on the volume control devices. INTEL the Z80 is one of the earliest in accordance with this idea to design the processor, From then on, the MCU and the development of a dedicated processor parted ways.Early singlechip 8bit or all of four. One of the most successful are INTEL39。s 8031, because the performance of a good reliable and easy access to great acclaim. Later on in 8031 developed a series of singlechip microputer system MCS51. Based on singlechip microputer system of the system is still widely used until now. As the field of industrial control requirements improve, beginning a 16bit singlechip, but not ideal because costeffective has not been very widely used. After the 9039。s with the big consumer electronics product development, singlechip technology has been enormous INTEL i960 series, especially the later series of widely used ARM, 32bit singlechip 16bit singlechip microputer rapidly replacing highend status, and enter the mainstream market. Whereas the traditional 8bit MCU performance has been the rapid increase in processing power pared to the 8039。s to raise a few hundred times. At present, the highend singlechip 32 GHz has been more than 300MHz, the performance of close on the heels of the mid9039。s dedicated processor, while the general model exfactory price dropped to one . dollars, the most highend models, only 10 . dollars. Contemporary singlechip microputer system is no longer only in the baremetal environment development and use of a large number of dedicated embedded operating system is widely used in on a full range of singlechip microputer. In the cell phone as a handheld puter and deal with highend singlechip core can even direct the use of a dedicated Windows and Linux operating systems.Singlechip is more suitable than a dedicated processor used in embedded systems, so it was up to the application. In fact the number of singlechip is the world39。s largest puter. Modern human life used in almost every piece of electronic and machinery products will have singlechip integration. Cell phone, telephone, calculator, home appliances, electronic toys, handheld puter and the puter mouse and other fittings are equipped with the Ministry of Singlechip 12. Personal puter will also have a large number of singlechip microputer at work. General Motors on the Ministry of singlechip microputer is equipped with more than 40 plex industrial control systems there is probably even hundreds of singlechip at the same time job! SCM is not only far exceeds the number of PC and other puting General, even more so than human beings than quantity.Introduce SinglechipSinglechip, also known as singlechip microcontroller, it is not pleted by a certain logic function of the chip, but put into a puter system on a chip. General stresses: a chip bees a puter. Its small size, light weight, cheap, for the study, application and development of facilities provided. At the same time, are studying the use of singlechip puter know the principle and structure of the best selection. Singlechip and puter also with similar functional modules, such as CPU, memory, parallel bus, and hard disk have the same effect as the memory difference is that its performance of these ponents are relatively weak . home puter much, but The prices and fees are low, there is generally no more than 10 yuan you can do with it some control for a class of electrical work is not very plex is sufficient. We are now using fully automatic drum washing machines, smoke hood, VCD and so on inside the home appliances can see its shadow! It is mainly as a control are part of the core ponents.It is an online realtime control puter, is the sceneline control is required there is a strong antiinterference ability, low cost, which is and offline puter (such as home PC) The main difference. Singlechip are relying on the procedure, and can be amended. Through different procedures achieve different functions, in particular, are special and unique features, which other devices are required fee in order to do a great effort, while some are also very difficult to make great efforts to do so. Is not a very plicated function of the United States if the 5039。s with the development of 74 series, or 6039。s CD4000 series of these pure hardware to get, then, the circuit must be a big PCB board! However, if the 70s if the United States successfully used to market a series of singlechip, the result will be different! MCU because only through the preparation of the procedures you can achieve high intelligence, highefficiency, as well as high reliability!Singlechip are because of the costsensitive, so the current dominant software or the lowest level assembly language, it is apart from the lowest level for more than binary machine code language, and now that so many lowlevel s
