基于Windows CE的嵌入式開發(fā)研究 Research of Embedded Development Based on Windows CE 【摘要】 近年來基于嵌入式系統(tǒng)的數(shù)字化產(chǎn)品在全球范圍內(nèi)得到了突飛猛進的發(fā)展，嵌入式技術(shù)已成為一個研究熱點和消費熱點。而Windows CE由于它的多任務(wù)、實時性、模塊化、強大的通信能力等特點，在嵌入式系統(tǒng)的諸多領(lǐng)域都有了廣泛的應(yīng)用。本文首先探討了嵌入式系統(tǒng)的特點，分類，前景，然后對各種嵌入式操作系統(tǒng)和Windows CE的特點及開發(fā)工具進行分析比較，接著介紹一個我們在Microsoft Windows CE 5.0環(huán)境下基于eBoxII開發(fā)的智能家居安防保全系統(tǒng)eDog。eDog 可以通過攝像頭將采集到的實時視頻圖像進行運動檢測，當發(fā)現(xiàn)有運動產(chǎn)生時，通過撥打電話等多種方式自動向用戶發(fā)出警報，同時將實時捕獲的圖像上傳到ftp 服務(wù)器。文章的最后詳細闡述了eDog的圖像采集模塊，運動圖像檢測模塊，圖像壓縮模塊，F(xiàn)TP上傳模塊的實現(xiàn)過程，并對我們所提出的運動檢測算法，視頻捕捉算法等做了詳細的說明。

There are many different (and often confusing) terms associated with clock-based devices. This application note attempts to clarify these terms, and hence serves as a comprehensive reference on clock terminology. This application note can be divided into two sections. The first section describes and distinguishes between various clock sources available today. The second section defines and distinguishes between various parameters used to describe clocks. This section also provides methods of measuring some of these parameters.

Jitter is extremely important in systems using PLL-based clock drivers. The effects of jitter range from not having any effect on system operation to rendering the system completely non-functional. This application note provides the reader with a clear understanding of jitter in high-speed systems. It introduces the reader to various kinds of jitter in high-speed systems, their causes and their effects, and methods of reducing jitter. This application note will concentrate on jitter in PLL-based frequency synthesizers.

SVMhmm: Learns a hidden Markov model from examples. Training examples (e.g. for part-of-speech tagging) specify the sequence of words along with the correct assignment of tags (i.e. states). The goal is to predict the tag sequences for new sentences.
