Summary speaking: A chip has bee a puter. Its volume is small, the quality is light, and the price cheap, for the study, the application and the development has provided the convenient condition. At the same time, the study use monolithic integrated circuit is understands the puter principle and the structure best choice.單片機(jī)又稱單片微控制器，它不是完成某一個(gè)邏輯功能的芯片，而是把一個(gè)計(jì)算機(jī)系統(tǒng)集成到一個(gè)芯片上。概括的講：一塊芯片就成了一臺(tái)計(jì)算機(jī)。它的體積小、質(zhì)量輕、價(jià)格便宜、為學(xué)習(xí)、應(yīng)用和開(kāi)發(fā)提供了便利條件。同時(shí)，學(xué)習(xí)使用單片機(jī)是了解計(jì)算機(jī)原理與結(jié)構(gòu)的最佳選擇。 The monolithic integrated circuit interior also uses with the puter function similar module, for instance CPU, memory, parallel main line, but also has with the hard disk behave identically the memory ponent7 what is different is its these part performance is opposite our homeuse puter weak many, but the price is also low, generally does not surpass 10 Yuan then Made some control electric appliance one kind with it is not the 39。very plex work foot, We use now the pletely automatic drum washer, the platoon petticoat pipe: VCD and so on Inside the electrical appliances may see its form! It is mainly takes the control section the core part.單片機(jī)內(nèi)部也用和電腦功能類似的模塊，比如CPU，內(nèi)存，并行總線，還有和硬盤(pán)作用相同的存儲(chǔ)器件，不同的是它的這些部件性能都相對(duì)我們的家用電腦弱很多，不過(guò)價(jià)錢也是低的，一般不超過(guò)10元即可，用它來(lái)做一些控制電器一類不是很復(fù)雜的工作足矣了。我們現(xiàn)在用的全自動(dòng)滾筒洗農(nóng)機(jī)、排煙罩、VCD等等的家電里面都可以看到它的身影！它主要是作為控制部分的核心部件。 It is one kind of online like realtime control puter, online like is the scene control, needs to have the strong antijamming ability, the low cost, this is also and the offline type puter (for instance home use PC,) main difference 它是一種存線式實(shí)時(shí)控制計(jì)算機(jī)，在線式就是現(xiàn)場(chǎng)控制，需要的是有較強(qiáng)的抗干擾能力，較低的成本，這也是和離線式計(jì)算機(jī)的（比如家用PC）的主要區(qū)別。 The monolithic integrated circuit is depending on the procedure, and may revise. Realizes the different function through the different procedure, particularly special unique some functions, this is other ponent needs to take the very big effort to be able to achieve, some are the flowered big strength is also very difficult to achieve. One is not the very plex function, if develops in the 50s with the US 74 series, or the 60s39。s CD4000 series these pure hardware do decides, the electric circuit certainly arc a big PCB board ! But if, if succeeded in the 70s with the US puts in the market the series monolithic integrated circuit, the result will have the huge difference. Because only the monolithic integrated circuit piles through you the procedure may realize the high intelligence, high efficiency, as well as redundant reliability 單片機(jī)是靠程序的，并且可以修改。通過(guò)不同的程序?qū)崿F(xiàn)不同的功能，尤其是特殊的獨(dú)特的一些功能，這是別的器件需要費(fèi)很多人力氣才能做到的，有些則是花人力氣也很難做到的。一個(gè)不是很復(fù)雜的功能要是用美同50年代開(kāi)發(fā)的74系列，或者60年代的CD4000系列這些純硬件來(lái)搞定的話，電路一定是一塊大PCB板！但是如果要是用美國(guó)70年代成功投放市場(chǎng)的系列單片機(jī)，結(jié)果就會(huì)有天壤之別！只因?yàn)閱纹瑱C(jī)的通過(guò)你編寫(xiě)的程序可以實(shí)現(xiàn)高科能，高效率，以及高可靠性！ The CPU is the key ponent of a digital puter. Its purpose is to decode
