簡介：論文題目聲波測井數(shù)據(jù)壓縮算法的嵌入式開發(fā)與實現(xiàn)專業(yè)通信與信息系統(tǒng)碩士生曹芳彤（簽名）指導老師蘇揚（簽名）摘要測井是石油勘探和開發(fā)過程中評估油藏的一種重要的方法，而聲波測井已成為當前主流的一種測井技術(shù)。由于聲波測井會產(chǎn)生龐大的數(shù)據(jù)量，當其要求的數(shù)據(jù)傳輸率過高而無法實時傳輸時，可采用存儲式儀器對這些數(shù)據(jù)進行井下存儲。為了減小儀器的存儲壓力，需要對數(shù)據(jù)進行壓縮處理。為此本文設(shè)計了一種基于LEMPELZIVWELCH（LZW）的聲波測井數(shù)據(jù)壓縮算法，并進行了嵌入式開發(fā)與實現(xiàn)。首先，通過對常用的各種數(shù)據(jù)壓縮算法的優(yōu)缺點比較分析，并結(jié)合系統(tǒng)實際設(shè)計要求，選擇LZW算法作為核心算法，并針對LZW算法編碼時采用固定的碼長進行壓縮編碼的方式以及字典的存儲容量有限等方面的缺點，對LZW算法進行了改進。為了提高壓縮效率，本文提出了將MEDIANEDGEDETECT（MED）模型與LZW融合的一種壓縮算法。通過MED模型對原始的聲波數(shù)據(jù)預測，并將其預測誤差作為數(shù)據(jù)壓縮的對象，再經(jīng)過改進的LZW算法壓縮，進一步提高了壓縮效率。其次，根據(jù)嵌入式系統(tǒng)開發(fā)的流程，在對系統(tǒng)需求分析的基礎(chǔ)上，確定了系統(tǒng)的硬件和操作系統(tǒng)構(gòu)成，選擇OK6410微處理器作為系統(tǒng)處理核心及LINUX作為嵌入式開發(fā)的操作系統(tǒng)，在此基礎(chǔ)上確定了系統(tǒng)硬件和軟件概要設(shè)計，隨后逐步說明了數(shù)據(jù)壓縮、傳輸過程中需要解決的關(guān)鍵技術(shù)。最后將開發(fā)板和PC機等設(shè)備相連后，對整個系統(tǒng)進行了測試評價。實驗測試結(jié)果表明，本文設(shè)計的聲波測井數(shù)據(jù)壓縮系統(tǒng)實現(xiàn)了聲波測井數(shù)據(jù)壓縮、數(shù)據(jù)存儲、數(shù)據(jù)傳輸以及數(shù)據(jù)解壓恢復的功能。所提出的基于MED預測的LZW壓縮算法能夠大幅度提高壓縮效率，且能夠無失真地恢復數(shù)據(jù)，達到了預期的效果。這對聲波測井儀中聲波數(shù)據(jù)的壓縮與傳輸具有較高的應用價值。關(guān)鍵詞聲波測井；LEMPLEZIVWELCH；MEDIANEDGEDETECT；嵌入式系統(tǒng)研究類型理論研究SUBJECTEMBEDDEDDEVELOPMENTREALIZATIONOFACOUSTICLOGGINGDATACOMPRESSIONALGITHMSPECIALTYCOMMUNICATIONINFMATIONSYSTEMNAMECAOFANGTONGSIGNATUREINSTRUCTSUYANGSIGNATUREABSTRACTLOGGINGISAKINDOFIMPTANTMETHOD，ITCANEVALUATERESERVOIRINTHEPROCESSOFOILEXPLATIONDEVELOPMENTACOUSTICLOGGINGISACURRENTTECHNOLOGYTHEACOUSTICLOGGINGWILLPRODUCEALARGEAMOUNTOFDATAWHENTHEREQUIREDDATARATEISTOOHIGHTOACHIEVEREALTIMETRANSMISSIONITCANUSETHEDATASTAGEINSTRUMENTTOSTETHEDATAINDERTEDUCETHESTAGEPRESSUREINSTRUMENTTHEDATANEEDTOBECOMPRESSEDTHEREFETHISPAPERDESIGNEDAKINDOFACOUSTICLOGGINGDATACOMPRESSIONALGITHMWHICHWASBASEDONLEMPELZIVWELCHLZWCOMPLETEDEMBEDDEDDEVELOPMENTIMPLEMENTATIONFIRSTOFALLTHROUGHTHEADVANTAGESDISADVANTAGESOFVARIOUSDATACOMPRESSIONALGITHMSWERECOMPAREDANALYZEDACCDINGTOTHEDEMOFTHEACTUALREQUIREMENTSOFTHESYSTEMASTHECEALGITHMLZWALGITHMWASEDLZWALGITHMUSEDTHEFIXEDCODELENGTHCOMPRESSIONCODINGMETHODLIMITEDSTAGECAPACITYOFTHEDICTIONARYFTHISSHTCOMINGSLZWALGITHMWASIMPROVEDINDERTOIMPROVETHECOMPRESSIONEFFICIENCYINTHISPAPERANEWCOMPRESSIONALGITHMWASPROPOSEDWHICHMEDIANEDGEDETECTMEDMODELLZWWERECOMBINEDMEDMODELPREDICTINGTHEIGINALSOUNDWAVESDATAWASUSEDTHEPREDICTIONERRWASUSEDASTHEOBJECTOFDATACOMPRESSIONTHENTHEIMPROVEDLZWALGITHMWASUSEDTOCOMPRESSTHEDATAITCANIMPROVETHECOMPRESSIONEFFICIENCYSECONDLYACCDINGTOTHEPROCESSOFTHEEMBEDDEDSYSTEMDEVELOPMENTBASINGONTHEANALYSISOFSYSTEMREQUIREMENTSTHECOMPOSITIONOFTHEHARDWARESYSTEMOPERATINGSYSTEMWEREDETERMINEDOK6410MICROPROCESSWASCHOSENASTHESYSTEMPROCESSINGCELINUXWASCHOSENASTHEDEVELOPMENTOFEMBEDDEDOPERATINGSYSTEMONTHISBASISTHEGENERALDESIGNOFHARDWARESOFTWARESYSTEMWEREDETERMINEDTHENTHEINTRODUCINGOFTHEKEYTECHNOLOGYINDATACOMPRESSIONTHEPROCESSOFDATATRANSMISSIONNEEDTOBESOLVEDFINALLYTHEDEVELOPMENTBOARDCOMPUTERWERECONNECTEDTOTESTEVALUATETHEWHOLESYSTEMTHEEXPERIMENTALTESTRESULTSSHOWTHATTHEDESIGNEDOFACOUSTICLOGGINGDATACOMPRESSION

簡介：面向嵌入式應用的動態(tài)加載機制研究重慶大學碩士學位論文學生姓名寧濤指導教師王錚副教授專業(yè)計算機軟件與理論學科門類工學重慶大學計算機學院二OO八年五月重慶大學碩士學位論文中文摘要I摘要嵌入式系統(tǒng)的廣泛應用需要良好的軟件系統(tǒng)支撐。隨著嵌入式系統(tǒng)的深入發(fā)展，系統(tǒng)的可擴展能力已成為一個基本的需求，迫切需要一種機制能在運行狀態(tài)下配置系統(tǒng)，也就是系統(tǒng)在運行狀態(tài)下可以動態(tài)地添加模塊，這種機制就是本論文要研究的動態(tài)加載機制。本論文討論的動態(tài)加載機制是應用從零開始的加載機制。這樣，系統(tǒng)只需要一個動態(tài)加載機制，就可以動態(tài)地加載模塊以配置適合不同應用需要的嵌入式系統(tǒng)。本論文分析了目前存在的幾種加載方式基于JAVA的動態(tài)加載方式、嵌入式LINUX的動態(tài)加載方式以及WINDOWS的動態(tài)鏈接庫原理，在此基礎(chǔ)上提出了面向嵌入式應用的動態(tài)加載機制的原理和過程。加載，是指將特定格式的模塊從外存或ROM甚至宿主開發(fā)環(huán)境裝入內(nèi)存并使之可以運行的過程。所謂動態(tài)加載，指的是，程序在運行期間需要調(diào)用某一模塊的功能時，由加載器將該模塊即時載入內(nèi)存，進行相應的重定位處理后將控制權(quán)交還調(diào)用程序。動態(tài)加載機制運用動態(tài)鏈接的原理使得系統(tǒng)具有動態(tài)的加載和動態(tài)解析的能力，模塊只有在被調(diào)用執(zhí)行時才被鏈接入系統(tǒng)。動態(tài)加載分為下載、加載和卸載三個操作，其中下載完成從遠程下載目標模塊到本地，加載操作完成讀入模塊到內(nèi)存，然后對模塊未解決的外部引用進行解析（也就是符號解析和重定位）使之可以運行的過程。當模塊不再使用時就從內(nèi)存中卸載。本文首先以目標模塊的生命周期為主線，在主線上側(cè)重表現(xiàn)了目標模塊的加載、處理、執(zhí)行和卸載的過程，對動態(tài)加載技術(shù)涉及到的背景知識進行系統(tǒng)的分析和討論，指出動態(tài)加載技術(shù)的關(guān)鍵和發(fā)展重點在于符號管理、符號解析和重定位技術(shù)，并對它們進行了較為全面的研究和分析。然后，針對這些關(guān)鍵問題給出了具體的實現(xiàn)方法。最后，在以上分析討論的基礎(chǔ)上提出了一種嵌入式系統(tǒng)的動態(tài)加載解決方案，描述了相關(guān)數(shù)據(jù)結(jié)構(gòu)和算法，實現(xiàn)了函數(shù)原型，測試并驗證了這一方案的可行性。關(guān)鍵詞關(guān)鍵詞動態(tài)加載，嵌入式系統(tǒng)，動態(tài)鏈接，ELF目標模塊
