現代的電子設計和芯片制造技術正在飛速發展，電子產品的復雜度、時鐘和總線頻率等等都呈快速上升趨勢，但系統的電壓卻不斷在減小，所有的這一切加上產品投放市場的時間要求給設計師帶來了前所未有的巨大壓力。要想保證產品的一次性成功就必須能預見設計中可能出現的各種問題，并及時給出合理的解決方案，對于高速的數字電路來說，最令人頭大的莫過于如何確保瞬時跳變的數字信號通過較長的一段傳輸線，還能完整地被接收，并保證良好的電磁兼容性，這就是目前頗受關注的信號完整性（SI）問題。本章就是圍繞信號完整性的問題，讓大家對高速電路有個基本的認識，并介紹一些相關的基本概念。

本書分為上篇、中篇和下篇三個部分，上篇為Windows CE結構分析，中篇為Windows CE情景分析，下篇為實驗手冊。每一篇又劃分為若 干章。上篇包含有引言，Windows CE體系結構，處理 器排程，儲存管理 ，檔案系統和設備管理 等六 章。中篇包含有系統初始化，處理 器排程過程，分頁處理 ，檔案處理 和驅動器載入等五章。下篇包含有Windows CE應用程式開發，Windows CE系統開發，評測與總結以及實習等四章。 上篇的重點在於分析Windows CE kernel的結構以及工作原理 。這個部分是掌握Windows CE作業系統的基礎。 中篇重點在於分析Windows CE kernel的實際運行 過程。如果說 上篇是從靜態的角度 分析Windows CE kernel，那麼中篇則是試圖從動態的角度 給讀 者一個有關Windows CE kernel的描述。希望讀 者能夠通過對中篇的閱讀 理 解，在頭腦中形成有關Windows CE kernel的多方位的運作情景。 下篇著重於有關Windows CE的應用。對理 論 的掌握最終要應用到實務中。
