簡介：嵌入式交叉調(diào)試器解決了在低配置目標(biāo)主機(jī)上不能直接運(yùn)行調(diào)試器的問題，實(shí)現(xiàn)在主機(jī)端運(yùn)行調(diào)試器，目標(biāo)端使用調(diào)試代理，兩者通過網(wǎng)絡(luò)或串口進(jìn)行連接完成嵌入式交叉調(diào)試的任務(wù)。為了開發(fā)出一款界面友好的嵌入式源碼級(jí)交叉調(diào)試器，對(duì)遠(yuǎn)程串行通訊協(xié)議數(shù)據(jù)包的格式和調(diào)試代理GDBSERVER存在的弊端進(jìn)行了分析，在此基礎(chǔ)上增加了對(duì)調(diào)試代理的控制，實(shí)現(xiàn)了目標(biāo)程序的自動(dòng)下載和調(diào)試控制的功能，并且對(duì)調(diào)試代理增加了重啟的功能，避免了部分理弊端的產(chǎn)生。交叉調(diào)試器主機(jī)端和目標(biāo)端的連接是交叉調(diào)試的基礎(chǔ)，為了能夠在沒有網(wǎng)絡(luò)設(shè)備的目標(biāo)機(jī)上實(shí)現(xiàn)調(diào)試功能，使用虛擬網(wǎng)絡(luò)設(shè)備的驅(qū)動(dòng)虛擬出一個(gè)網(wǎng)絡(luò)設(shè)備，用于交叉調(diào)試器基于USB的網(wǎng)絡(luò)連接。對(duì)基于USB的虛擬網(wǎng)絡(luò)的原理以及要修改的層次結(jié)構(gòu)進(jìn)行了分析，調(diào)試時(shí)主機(jī)端（WINDOWS系統(tǒng)）使用NDIS，目標(biāo)端使用USB設(shè)備控制器來實(shí)現(xiàn)USB虛擬網(wǎng)絡(luò)的功能。圖形界面操作的調(diào)試器使調(diào)試過程變的相對(duì)簡單，為此對(duì)調(diào)試器加入了具有圖形化操作功能的顯示模塊。顯示模塊是用戶直接接觸的模塊，該模塊能夠讓用戶使用圖形界面對(duì)調(diào)試器進(jìn)行操作，如設(shè)置與清除斷點(diǎn)，查看與修改內(nèi)存，查看與修改寄存器等，另外顯示模塊對(duì)于調(diào)試程序而言能夠提供源碼顯示視圖。

簡介：由于指紋的唯一性、不變性的特點(diǎn)，指紋識(shí)別技術(shù)成為最可靠、最成熟的生物識(shí)別技術(shù)，并越來越廣泛地應(yīng)用到各種領(lǐng)域。目前自動(dòng)指紋識(shí)別系統(tǒng)大多是基于PC平臺(tái)的，但隨著時(shí)代的發(fā)展，市場開始對(duì)自動(dòng)指紋識(shí)別系統(tǒng)提出小型化的要求。而嵌入式自動(dòng)指紋識(shí)別系統(tǒng)由于其便攜性、易用性的特點(diǎn)，較好得滿足了這一特點(diǎn)，逐漸成為自動(dòng)指紋識(shí)別系統(tǒng)的主流。本文結(jié)合嵌入式技術(shù)和指紋處理算法，針對(duì)嵌入式自動(dòng)指紋識(shí)別系統(tǒng)進(jìn)行了研究，主要從系統(tǒng)硬件設(shè)計(jì)、系統(tǒng)軟件設(shè)計(jì)、指紋算法移植和優(yōu)化三個(gè)方面對(duì)整個(gè)系統(tǒng)設(shè)計(jì)進(jìn)行了介紹。針對(duì)系統(tǒng)設(shè)計(jì)中的一些關(guān)鍵單元和關(guān)鍵問題，本文給出了解決方法。本文所做的工作主要包括以下幾個(gè)方面首先，本文為嵌入式自動(dòng)指紋識(shí)別系統(tǒng)的實(shí)現(xiàn)提出了一套切實(shí)可行的硬件方案。方案詳細(xì)討論了各個(gè)關(guān)鍵模塊的硬件選型和原理圖設(shè)計(jì)。該方案以PXA255處理器為核心，滿足了大部分場合下自動(dòng)指紋識(shí)別系統(tǒng)的需求。其次，本文針對(duì)所提出的硬件平臺(tái)設(shè)計(jì)了一套比較完整的系統(tǒng)軟件解決方案，并詳細(xì)闡述了各個(gè)功能模塊的軟件設(shè)計(jì)方法。該軟件方案較好地滿足了系統(tǒng)功能需求，并且易于在該方案的框架下擴(kuò)展各種功能。最后，本文針對(duì)嵌入式平臺(tái)，對(duì)指紋識(shí)別算法進(jìn)行了移植和優(yōu)化，使之能夠滿足實(shí)時(shí)性的需求。在優(yōu)化過程當(dāng)中，參考其他文獻(xiàn)，總結(jié)了一些優(yōu)化原則和優(yōu)化方法，大大提高了算法的運(yùn)行速度。對(duì)于一般的嵌入式軟件優(yōu)化，該優(yōu)化原則和方法同樣很有意義。試驗(yàn)證明，本文設(shè)計(jì)的指紋識(shí)別系統(tǒng)在便攜性、可靠性、實(shí)時(shí)性和設(shè)備成本方面都基本達(dá)到令人滿意的效果。

簡介：語音識(shí)別和嵌入式是當(dāng)今熱點(diǎn)，其產(chǎn)品應(yīng)用前景十分廣闊，將語音識(shí)別應(yīng)用到嵌入式系統(tǒng)中，更是能夠發(fā)揮兩者的優(yōu)點(diǎn)。本文主要研究嵌入式孤立字語音識(shí)別，主要研究設(shè)計(jì)語音識(shí)別算法動(dòng)態(tài)時(shí)間規(guī)整算法DTW和隱馬爾科夫算法HMM，然后編寫了基于LINUX和ARM芯片的音頻驅(qū)動(dòng)并對(duì)其進(jìn)行了測試。本文在語音識(shí)別算法方面，首先建立了語音識(shí)別系統(tǒng)的發(fā)聲模型，然后對(duì)語音進(jìn)行預(yù)處理，即對(duì)數(shù)字信號(hào)預(yù)加重、分幀和加窗，接著對(duì)語音信號(hào)提取特征參數(shù)，提取特征參數(shù)的方法采用線性預(yù)測倒譜系數(shù)法和美爾倒譜系數(shù)法，再接下來是要對(duì)提取出來的特征矢量進(jìn)行矢量量化，從而壓縮數(shù)據(jù)。最后重點(diǎn)分析設(shè)計(jì)了動(dòng)態(tài)時(shí)間規(guī)整DTWDYNAMICTIMEWARPING識(shí)別算法和隱馬爾科夫HMMHIDDENMARKOVMODEL識(shí)別算法。DTW主要是通過尋找動(dòng)態(tài)時(shí)間規(guī)整函數(shù)來使輸入模塊與參考模塊之間的誤差達(dá)到最小，從而得出語音識(shí)別的相似誤差。隱馬爾科夫HMM識(shí)別算法主要是解決求觀察值概率的問題、求最佳狀態(tài)序列的問題和在什么情況下觀察值概率最大的問題?；谝陨蟽蓚€(gè)模型基礎(chǔ)，本文設(shè)計(jì)了MATLAB語音識(shí)別代碼，得到了期望識(shí)別結(jié)果。在嵌入式方面，本文采用的操作系統(tǒng)為LINUX系統(tǒng)，硬件平臺(tái)使用友善之臂的MINI2440開發(fā)板，主要使用了開發(fā)板上聲卡資源和LED資源，以及調(diào)試所用的串口。編寫了音頻驅(qū)動(dòng)DEVDSP和DEVMIXER，它們分別對(duì)應(yīng)著音頻驅(qū)動(dòng)的兩個(gè)部分，一個(gè)是主要用來錄音播音的，另一個(gè)是用來對(duì)聲音的大小進(jìn)行控制。驅(qū)動(dòng)編譯成功后，然后加載進(jìn)系統(tǒng)內(nèi)核，并通過音頻測試程序來測試上述兩個(gè)設(shè)備。在開發(fā)應(yīng)用試驗(yàn)方面，本文是通過語音來控制LED燈，不同的語音信號(hào)發(fā)出時(shí)LED燈就會(huì)處于不同的狀態(tài)，以達(dá)到語音控制嵌入式設(shè)備的目的。最后提出了語音控制機(jī)場地勤服務(wù)的應(yīng)用，并做了一些語音識(shí)別技術(shù)的研究，為后續(xù)研究打下基礎(chǔ)。

簡介：諸如手機(jī)、GPS、PDA等嵌入式移動(dòng)設(shè)備已經(jīng)成為目前運(yùn)用最為廣泛的具備顯示功能的計(jì)算機(jī)系統(tǒng)，因此該類型的嵌入式移動(dòng)設(shè)備已成為向用戶提供先進(jìn)圖形交互技術(shù)體驗(yàn)的重要載體。隨著嵌入式設(shè)備運(yùn)算能力的迅速發(fā)展和三維圖形技術(shù)的日益成熟，通過在圖形系統(tǒng)中融入三維技術(shù)來為用戶提供更加美觀和人性化的圖形用戶界面已逐步成為圖形系統(tǒng)和圖形用戶界面的重要發(fā)展趨勢。嵌入式窗口特效在基于X11協(xié)議的嵌入式圖形系統(tǒng)CLEARX之上進(jìn)行設(shè)計(jì)開發(fā)。在保持CLEARX內(nèi)部結(jié)構(gòu)和外部接口穩(wěn)定不變的情況下，充分利用三星S3C6410處理器支持的多層屏幕及硬件雙顯示緩存等功能，實(shí)現(xiàn)窗口特效顯示與圖形系統(tǒng)顯示之間的融合。根據(jù)模塊化的分層結(jié)構(gòu)設(shè)計(jì)方式，嵌入式窗口特效的總體設(shè)計(jì)依據(jù)功能劃分為窗口特效層和三維圖形處理層兩層。窗口特效層中最為核心的問題就是窗口的特效顯示。解決方案是通過圖形系統(tǒng)將參與特效顯示的窗口繪制到一塊內(nèi)存屏幕中，然后把內(nèi)存屏幕中的窗口圖像通過三維圖形技術(shù)中的紋理映射方法顯示出來，從而達(dá)到窗口扭曲形變顯示的目的。參與特效顯示的窗口都被等同于二維紋理對(duì)待，所以在窗口特效設(shè)計(jì)中允許使用其它圖像數(shù)據(jù)來代替窗口參與到窗口特效的顯示之中，豐富了嵌入式窗口特效的顯示內(nèi)容和功能。三維圖形處理層主要功能是利用S3C6410所集成的三維圖形加速模塊向上層提供一個(gè)簡單高效的三維圖形加速庫。在這一層中單獨(dú)加入了本地顯示接口和顯示緩存管理模塊用于處理窗口特效顯示、紋理處理等相關(guān)問題。
