【正文】 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 many of our home puter, but the price is low , usually not more than 10 yuan you can do with it some control for a class is not very plicated electrical work is enough of。s with the United States developed 74 series, or the 6039。 Can be said that the twentieth century across the three power era, that is, the age of electricity, the electronic age and has entered into the puter age. However, this puter, usually refers to the personal puter, referred to as PC. It consists of the host, keyboard, monitor and other ponents. Another type of puter, most people do not know how. This puter is to give all kinds of intelligent machines single chip (also known as microcontroller). As the name suggests, this puter system took only a minimal integrated circuit, can be a simple operation and control。 the microcontroller (Micro Controller Unit) stage, the main direction of technology development: expanding to meet the embedded applications, the target system requirements for the various peripheral circuits and interface circuits, highlight the object of intelligent involves the areas associated with the object system, therefore, the development of MCU39。 MCU applications： SCM now permeate all areas of our lives, which is almost difficult to find traces of the field without SCM. Missile navigation equipment, aircraft, all types of instrument control, puter work munications and data transmission, industrial automation, realtime process control and data processing, extensive use of various smart IC card, civilian luxury car security system, video recorder, camera, fully automatic washing machine control, and programcontrolled toys, electronic pet, etc 。 can quickly adjust the voltage。 INTEL的 Z80 是最早按照這種思想設(shè)計(jì)出的處理器，從此以后，單片機(jī)和專用處理器的發(fā)展便分道揚(yáng)鑣?；谶@一系統(tǒng)的單片機(jī)系統(tǒng)直到現(xiàn)在還在廣泛使用。而傳統(tǒng)的 8 位單片機(jī)的性能也得到了飛速提高，處理能力比起 80 年代提高了數(shù)百倍。 單片機(jī)比專用處理器更適合應(yīng)用于 嵌入式系統(tǒng) ，因此它得到了最多的應(yīng)用。而個(gè)人電腦中也會(huì)有為數(shù)不少的單片機(jī)在工作。概括的講：一塊芯片就成了一臺(tái)計(jì)算機(jī)。我們現(xiàn)在用的全自動(dòng)滾筒洗衣機(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。一個(gè)不是很復(fù)雜的功能要是用美國(guó) 50 年代開發(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?機(jī)的通過(guò)你編寫的程序可以實(shí)現(xiàn)高智能，高效率，以及高可靠性！ 由于單片機(jī)對(duì)成本是敏感的，所以目前占統(tǒng)治地位的軟件還是最低級(jí) 匯編 語(yǔ)言，它是除了二進(jìn)制機(jī)器碼以上最低級(jí)的語(yǔ)言了，既然這么低級(jí)為什么還要用呢？很多高級(jí)的語(yǔ)言已經(jīng)達(dá)到了可視化編程的水平為什么不用呢？原因很簡(jiǎn)單，就是單片機(jī)沒(méi)有家用計(jì)算機(jī)那樣的 CPU，也沒(méi)有像硬盤那樣的海量存儲(chǔ)設(shè)備。 可以說(shuō)，二十世紀(jì)跨越了三個(gè) “ 電 ” 的時(shí)代，即電氣時(shí)代、電子時(shí)代和現(xiàn)已進(jìn)入的電腦時(shí)代。這種計(jì)算機(jī)就是把智能賦予各種機(jī)械的單片機(jī)（ 亦稱微控制器）。現(xiàn)在，這種單片機(jī)的使用領(lǐng)域已十分廣泛，如 智能儀表 、實(shí)時(shí)工控、通訊設(shè)備、 8 導(dǎo)航系統(tǒng)、家用電器等。 單片機(jī)歷史 單片機(jī)誕生于 20 世紀(jì) 70 年代末，經(jīng)歷了 SCM、 MCU、 SoC 三大階段。 2 MCU 即微控制器（ Micro Controller Unit）階段，主要的技術(shù)發(fā)展方向是：不斷擴(kuò)展?jié)M足嵌入式應(yīng)用時(shí)，對(duì)象系統(tǒng)要求的各種外圍電路與接口電路，突顯其對(duì)象的智能化控制能力。 Philips 公司以其在嵌入式應(yīng)用方面的巨大優(yōu)勢(shì)，將 MCS51 從單片微型計(jì)算機(jī)迅速發(fā)展到微控制器。因此，對(duì)單片機(jī)的理解可以從單片微型計(jì)算機(jī)、單片微控制器延伸到單片應(yīng)用系統(tǒng)。因此，單片機(jī)的學(xué)習(xí)、開發(fā)與應(yīng)用將造就一批計(jì)算機(jī)應(yīng)用與智能化控制的科學(xué)家、工程師。
