1、<p><b>  中文翻譯:</b></p><p>  從無線電世界到單片機(jī)世界 現(xiàn)代計(jì)算機(jī)技術(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(jiǎn)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 ,

2、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(cè),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)

3、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</p><p>  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

4、件,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(cè)領(lǐng)域中的信息采集,運(yùn)動(dòng)機(jī)械 對(duì)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

5、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),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</p><p&g

6、t;  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

7、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)智能化 奠定了基礎(chǔ).因此,當(dāng)前單片機(jī)在電子系統(tǒng)中的廣泛使用,使經(jīng)典電子系 統(tǒng)迅速過渡到智能化的現(xiàn)代電子系統(tǒng). 四 , 單片機(jī)開創(chuàng)了現(xiàn)代電子系統(tǒng)時(shí)代 1 單片機(jī)與嵌

8、入式系統(tǒng) 嵌入式系統(tǒng)源于計(jì)算機(jī)的嵌入式應(yīng)用,早期嵌入式系統(tǒng)為通用計(jì)算機(jī) 經(jīng)改裝后嵌入到對(duì)象體系中的各種電子系統(tǒng),如艦船的自動(dòng)駕駛</p><p>  機(jī)革新了原有電子系統(tǒng),如微波爐采用單片機(jī)控制后,可方便地進(jìn)行時(shí)鐘 設(shè)置,程序記憶,功率控制;空調(diào)機(jī)采用單片機(jī)后不但遙控參數(shù)設(shè)置方便, 運(yùn)行狀態(tài)自動(dòng)變換,還可實(shí)現(xiàn)變頻控制.目前許多家用電器如 VCD,DVD 只有單片機(jī)出現(xiàn)后才可能實(shí)現(xiàn)其功能. 3 嵌入式系統(tǒng)帶動(dòng)了整個(gè)

9、電子產(chǎn)業(yè) 目前電子元器件產(chǎn)業(yè)除了微處理器,嵌入式系統(tǒng)器件外,大多是圍繞 現(xiàn)代電子系統(tǒng)配套的元器件產(chǎn)業(yè),例如滿足人機(jī)交互用的按鍵,LED/LCD 顯示驅(qū)動(dòng),LED/LCD 顯示單元,語(yǔ)音集成器件等,滿足數(shù)據(jù)采集通道要求 的數(shù)字傳感器,ADC,數(shù)據(jù)采集模塊,信號(hào)調(diào)理模塊等,滿足伺服驅(qū)動(dòng)控 制的 DAC,固體繼電器,步進(jìn)電機(jī)控制器,變頻控制單元等,滿足通信要 求的各種總線驅(qū)動(dòng)器,電平轉(zhuǎn)換器等. 世界電子元器件在嵌入式系統(tǒng)帶動(dòng)下,沿著充分滿足嵌

10、入式應(yīng)用的現(xiàn) 代電子系統(tǒng)要求發(fā)展.這就使原來經(jīng)典電子系統(tǒng)的天地愈來愈小.電子系 統(tǒng)中的各類從業(yè)人員應(yīng)盡早轉(zhuǎn)向現(xiàn)代電子系統(tǒng)的康莊大道. 五 , 單片機(jī)將造就新一代電子精英 如果說五十年代起,無線電世界造就了幾代精英,那么當(dāng)今的單片機(jī) 世界將會(huì)造就出新一代電子精英. 1 單片機(jī)帶你進(jìn)入智能化電子領(lǐng)</p><p>  的智能化本質(zhì)并掌握智能化設(shè)計(jì)的知識(shí).從學(xué)習(xí)單片機(jī)應(yīng)用技術(shù)入手是當(dāng) 今培養(yǎng)計(jì)算機(jī)應(yīng)用軟,硬件技術(shù)人才的

11、最佳道路之一. 3 單片機(jī)帶你進(jìn)入最具魅力的電子世界 獨(dú)具魅力的單片機(jī)能使你體會(huì)到電腦的真諦,你可以用單片機(jī)親自動(dòng) 手設(shè)計(jì)智能玩具,可以設(shè)計(jì)不同的應(yīng)用程序?qū)崿F(xiàn)不同的功能.既有硬件制 作又有軟件設(shè)計(jì),既動(dòng)腦,又動(dòng)手.初級(jí)水平可開發(fā)智能玩具,用宏指令 編程.中級(jí)水平可開發(fā)一些智能控制器,如電腦鼠,智能車,各種遙控模 型.高級(jí)水平可開發(fā)機(jī)器人,如機(jī)器人足球賽,開發(fā)工業(yè)控制單元,網(wǎng)絡(luò) 通信等,并用匯編語(yǔ)言或高級(jí)語(yǔ)言設(shè)計(jì)應(yīng)用程序.圍繞單片機(jī)及嵌入

12、式系 統(tǒng)形成的電子產(chǎn)業(yè)的未來,將會(huì)為電子愛好者提供廣闊的天地,一個(gè)比當(dāng) 年無線電世界更廣闊,更豐富,更持久,更具魅力的電子世界.投身到單 片機(jī)世界來,將使你一生受益. 單片機(jī)攻擊技術(shù) 目前,攻擊單片機(jī)主要有四種技術(shù),分別是: ( 1 ) 軟件攻擊 該技術(shù)通常使用處理器通信接口并利用協(xié)議,加密算法或這些算法 中的安全漏洞來進(jìn)行攻擊.軟件攻擊取得成功的一個(gè)典型事例是對(duì)早期A TMEL AT89C 系列單片機(jī)的攻擊.攻擊者利用了該系列單片機(jī)擦

13、 除操作時(shí)序設(shè)計(jì)上的</p><p>  鐘瞬態(tài)跳變也許會(huì)復(fù)位保護(hù)電路而不會(huì)破壞受保護(hù)信息.電源和時(shí)鐘瞬態(tài) 跳變可以在某些處理器中影響單條指令的解碼和執(zhí)行. ( 4 ) 探針技術(shù) 該技術(shù)是直接暴露芯片內(nèi)部連線,然后觀察,操控,干擾單片機(jī)以達(dá) 到攻擊目的.為了方便起見,人們將以上四種攻擊技術(shù)分成兩類,一類是 侵入型攻擊(物理攻擊),這類攻擊需要破壞封裝,然后借助半導(dǎo)體測(cè)試 設(shè)備,顯微鏡和微定位器,在專門的實(shí)驗(yàn)室花上

14、幾小時(shí)甚至幾周時(shí)間才能 完成.所有的微探針技術(shù)都屬于侵入型攻擊.另外三種方法屬于非侵入型 攻擊,被攻擊的單片機(jī)不會(huì)被物理?yè)p壞.在某些場(chǎng)合非侵入型攻擊是特別 危險(xiǎn)的,但是因?yàn)榉乔秩胄凸羲柙O(shè)備通??梢宰灾坪蜕?jí),因此非常 廉價(jià). 大部分非侵入型攻擊需要攻擊者具備良好的處理器知識(shí)和軟件知識(shí). 與之相反,侵入型的探針攻擊則不需要太多的初始知識(shí),而且通??捎靡?整套相似的技術(shù)對(duì)付寬范圍的產(chǎn)品. 單片機(jī)侵入型攻擊的一般過程 侵入型攻擊的第一步是

15、揭去芯片封裝.有兩種方法可以達(dá)到這一目的: 第一種是完全溶解掉芯片封裝,暴露金屬連線.第二種是只移掉硅核上面 的塑料封裝.第一種方法需要將芯片綁定到測(cè)試夾具上,借助綁定臺(tái)來操 作.第二種</p><p>  掉保護(hù)位的保護(hù)作用,之后,使用簡(jiǎn)單的編程器就可直接讀出程序存儲(chǔ)器 的內(nèi)容. 對(duì)于使用了防護(hù)層來保護(hù)EEPROM單元的單片機(jī)來說,使用紫外 光復(fù)位保護(hù)電路是不可行的.對(duì)于這種類型的單片機(jī),一般使用微探針技 術(shù)來

16、讀取存儲(chǔ)器內(nèi)容.在芯片封裝打開后,將芯片置于顯微鏡下就能夠很 容易的找到從存儲(chǔ)器連到電路其它部分的數(shù)據(jù)總線. 由于某種原因,芯片鎖定位在編程模式下并不鎖定對(duì)存儲(chǔ)器的訪問. 利用這一缺陷將探針放在數(shù)據(jù)線的上面就能讀到所有想要的數(shù)據(jù).在編程 模式下,重啟讀過程并連接探針到另外的數(shù)據(jù)線上就可以讀出程序和數(shù)據(jù) 存儲(chǔ)器中的所有信息. 還有一種可能的攻擊手段是借助顯微鏡和激光切割機(jī)等設(shè)備來尋找保 護(hù)熔絲,從而尋查和這部分電路相聯(lián)系的所有信號(hào)線.由于

17、設(shè)計(jì)有缺陷, 因此,只要切斷從保護(hù)熔絲到其它電路的某一根信號(hào)線,就能禁止整個(gè)保 護(hù)功能.由于某種原因,這根線離其它的線非常遠(yuǎn),所以使用激光切割機(jī) 完全可以切斷這根線而不影響臨近線.這樣,使用簡(jiǎn)單的編程器就能直接 讀出程序存儲(chǔ)器的內(nèi)容. 雖然大多數(shù)普通單片機(jī)都具有熔絲燒斷保護(hù)單片機(jī)內(nèi)代碼的功能,但 由于通用低檔的單片機(jī)并非定位于制作安全類產(chǎn)品,因此,它</p><p>  EMC 單片機(jī) : 單片機(jī): 是臺(tái)灣義隆公
