48、術(shù)的產(chǎn)業(yè)革命,將世界經(jīng)濟(jì)從資本經(jīng)濟(jì)帶入到知識(shí)經(jīng)濟(jì)時(shí)代.在電子世界領(lǐng)域,從20世紀(jì)中的無線電時(shí)代也進(jìn)入到21世紀(jì)以計(jì)算機(jī)技術(shù)為中心的智能化現(xiàn)代電子系統(tǒng)時(shí)代.現(xiàn)代電子系統(tǒng)的基本核心是嵌入式計(jì)算機(jī)系統(tǒng)(簡稱嵌入式系統(tǒng)),而單片機(jī)是最典型,最廣泛,最普及的嵌入式系統(tǒng).一 , 無線電世界造就了幾代英才 在20世紀(jì)五六十年代,最具代表的先進(jìn)的電子技術(shù)就是無線電技術(shù),包括無線電廣播,收音,無線通信(電報(bào)),業(yè)余無線電臺(tái),無線電定位,導(dǎo)航等遙測,遙控,遙信技術(shù).早期就是這些電子技術(shù)帶領(lǐng)著許多青少年步入了奇妙的電子世界,無線電技術(shù)展示了當(dāng)時(shí)科技生活美妙的前景.電子 科學(xué)開始形成了一門新興學(xué)科.無線電電子學(xué),無線

49、通信開始了電子世界的歷程. 無線電技術(shù)不僅成為了當(dāng)時(shí)先進(jìn)科學(xué)技術(shù)的代表,而且從普及到專業(yè)的科學(xué)領(lǐng)域,吸引了廣大青少年,并使他們從中找到了無窮的樂趣.從床頭的礦石收音機(jī)到超外差收音機(jī);從無線電發(fā)報(bào)到業(yè)余無線電臺(tái);從電話,電鈴到無線電操縱模型.無線電技術(shù)成為當(dāng)時(shí)青少年科普,科技教 育最普及,最廣泛的內(nèi)容.至今,許多老一輩的工程師、專家、教授當(dāng)年都是無線電愛好者.無線電技術(shù)的無窮樂趣,無線電技術(shù)的全面訓(xùn)練,從電子學(xué)基本原理,電子元器件基礎(chǔ)到無線電遙控,遙測,遙信電子系統(tǒng)制作,培養(yǎng)出了幾代科技英才.二 , 從無線電時(shí)代到電子技術(shù)普及時(shí)代 早期的無線電技術(shù)推動(dòng)了電子技術(shù)的發(fā)展,其中最主要的是真空管電子技

50、術(shù)向半導(dǎo)體電子技術(shù)的發(fā)展.半導(dǎo)體電子技術(shù)使有源器件實(shí)現(xiàn)了微小型化和低成本,使無線電技術(shù)有了更大普及和創(chuàng)新,并大大地開闊了許多非無線電的控制領(lǐng)域. 半導(dǎo)體技術(shù)發(fā)展導(dǎo)致集成電路器件的產(chǎn)生,形成了近代電子技術(shù)的飛躍,電子技術(shù)從分立器件時(shí)代走進(jìn)了電路集成時(shí)代.電子設(shè)計(jì)工程師不再用分立的電子元器件設(shè)計(jì)電路單元,而直接選擇集成化的電路單元器件構(gòu)成系統(tǒng).他們從電路單元設(shè)計(jì)中解放出來,致力于系統(tǒng)設(shè)計(jì),大大地解放了科技生產(chǎn)力,促進(jìn)了電子系統(tǒng)更大范圍的普及.半導(dǎo)體集成電路首先在基本數(shù)字邏輯電路上取得突破.大量數(shù)字邏輯電路,如門電路,計(jì)數(shù)器,定時(shí)器,移位寄存器以及模擬開關(guān),比較器等,為電子數(shù)字控制提供了極佳的條件,

51、使傳統(tǒng)的機(jī)械控制轉(zhuǎn)向電子控制.功率電子器件以及傳感技術(shù)的發(fā)展使原先以無線電為中心的電子技術(shù)開始轉(zhuǎn)向工程領(lǐng)域中的機(jī)械系統(tǒng)的數(shù)字控制,檢測領(lǐng)域中的信息采集,運(yùn)動(dòng)機(jī)械對象的電氣伺服驅(qū)動(dòng)控制. 半導(dǎo)體及其集成電路技術(shù)將我們帶入了一個(gè)電子技術(shù)普及時(shí)代,無線電技術(shù)成為電子技術(shù)應(yīng)用領(lǐng)域的一個(gè)部分. 進(jìn)入 20 世紀(jì) 70 年代,大規(guī)模集成電路出現(xiàn),促進(jìn)了常規(guī)的電子電路單元的專用電子系統(tǒng)發(fā)展.許多專用電子系統(tǒng)單元變成了集成化器件,如收音機(jī),電子鐘,計(jì)算器等,在這些領(lǐng)域的電子工程師從電路,系統(tǒng)的精心設(shè)計(jì),調(diào)試轉(zhuǎn)變?yōu)槠骷x擇,外圍器件適配工作.電子技術(shù)發(fā)展了,電 子產(chǎn)品豐富了,電子工程師的難度減少了,但與此同時(shí),

52、無線電技術(shù),電子技術(shù)的魅力卻削弱了.半導(dǎo)體集成電路的發(fā)展使經(jīng)典電子系統(tǒng)日趨完善, 留在大規(guī)模集成電路以外的電子技術(shù)日益減少,電子技術(shù)沒有了往昔無線電時(shí)代的無窮樂趣和全面的工程訓(xùn)練. 三 , 從經(jīng)典電子技術(shù)時(shí)代到現(xiàn)代電子技術(shù)時(shí)代 進(jìn)入20世紀(jì)80年代,世紀(jì)經(jīng)濟(jì)中最重要的變革是計(jì)算機(jī)的產(chǎn)業(yè)革命.而計(jì)算機(jī)產(chǎn)業(yè)革命的最重要標(biāo)志則是計(jì)算機(jī)嵌入式應(yīng)用的誕生.近代電子計(jì)算機(jī)是應(yīng)數(shù)值計(jì)算要求誕生的.在很長的時(shí)間內(nèi),電子計(jì)算機(jī)都是以發(fā)展海量數(shù)值計(jì)算為己任.但是電子計(jì)算機(jī)表現(xiàn)出的邏輯運(yùn)算,處理,控制能力,吸引了電子控制領(lǐng)域的專家,他們要求發(fā)展能滿足控制對象要求,實(shí)現(xiàn)嵌入式應(yīng)用的計(jì)算機(jī)系統(tǒng).如果將滿足海量數(shù)據(jù)處理的

53、計(jì)算機(jī)系統(tǒng)稱為通用計(jì)算機(jī)系統(tǒng),那么則可把嵌入到對象體系(如艦船、飛機(jī)、機(jī)車等) 中的計(jì)算機(jī)系統(tǒng)稱作嵌入式計(jì)算機(jī).顯而易見,兩者的技術(shù)發(fā)展方向是不同的.前者要求海量數(shù)據(jù)存儲(chǔ),吞吐,高速數(shù)據(jù)處理分析及傳輸;而后者要求在對象環(huán)境中可靠運(yùn)行,對外部物理參數(shù)的高速采集,邏輯分析處理和對外部對象的快速控制等.早期人們將通用計(jì)算機(jī)加上數(shù)據(jù)采集單元,輸出驅(qū)動(dòng)電路勉為其難地構(gòu)成一個(gè)熱處理爐的溫控系統(tǒng).這樣的通用計(jì)算機(jī)系統(tǒng)不可能為大多數(shù)電子系統(tǒng)采用,而且要使通用計(jì)算機(jī)系統(tǒng)滿足嵌入式應(yīng)用要求,必然影響高速數(shù)值處理技術(shù)的發(fā)展.為了解決計(jì)算機(jī)技術(shù)發(fā)展的矛盾,在20世紀(jì)70年代,半導(dǎo)體專家另辟蹊徑,完全按照電子系統(tǒng)的計(jì)算

54、機(jī)嵌入式應(yīng)用要求,將一個(gè)微型計(jì)算機(jī)的基本系統(tǒng)集成在一個(gè)芯片上,形成了早期的單片機(jī)(single chip microcomputer).單片機(jī)問世后,在計(jì)算機(jī)領(lǐng)域中開始出現(xiàn)了通用計(jì)算機(jī)系統(tǒng)和嵌入式系統(tǒng)的兩大分支.此后, 無論是嵌入式系統(tǒng),還是通用計(jì)算機(jī)系統(tǒng)都得到了飛速的發(fā)展. 早期雖然有通用計(jì)算機(jī)改裝而成的嵌入式計(jì)算機(jī)系統(tǒng),而真正意義上的嵌入式系統(tǒng)始于單片機(jī)的出現(xiàn).因?yàn)閱纹瑱C(jī)是專門為嵌入式應(yīng)用設(shè)計(jì)的,單片機(jī)只能實(shí)現(xiàn)嵌入式應(yīng)用.單片機(jī)能最好地滿足嵌入式應(yīng)用的環(huán)境要求,例如,芯片級(jí)的物理空間,大規(guī)模集成電路的低價(jià)位,良好的外圍接口總線和突出控制功能的指令系統(tǒng). 單片機(jī)有計(jì)算機(jī)系統(tǒng)內(nèi)核,嵌入到電子系統(tǒng)中,為電子系統(tǒng)智能
