  • 基于ARM的遠(yuǎn)程視頻監(jiān)控系統(tǒng)研究

    視頻監(jiān)控系統(tǒng)是一門集計(jì)算機(jī)技術(shù)、通信技術(shù)和數(shù)字視頻技術(shù)于一體的綜合系統(tǒng)。目前視頻監(jiān)控正向著數(shù)字化、網(wǎng)絡(luò)化的方向發(fā)展。實(shí)現(xiàn)基于網(wǎng)絡(luò)的視頻監(jiān)控系統(tǒng)的關(guān)鍵是一種嵌入式設(shè)備,它應(yīng)該能夠采集壓縮視頻數(shù)據(jù)并通過網(wǎng)絡(luò)進(jìn)行傳輸。 本文介紹了一種基于嵌入式Linux的網(wǎng)絡(luò)視頻監(jiān)控系統(tǒng)的設(shè)計(jì)和實(shí)現(xiàn)方法。首先從整體上分析了網(wǎng)絡(luò)視頻監(jiān)控系統(tǒng)的總體設(shè)計(jì)方案,給出了視頻服務(wù)器的硬件框架和軟件體系,并重點(diǎn)討論了在ARM處理器上實(shí)現(xiàn)MPEG-4壓縮編碼的方法。其次在ARM硬件平臺(tái)成功構(gòu)建了armlinux嵌入式系統(tǒng):包括引導(dǎo)程序Bootloader的設(shè)計(jì)、修改配置linux內(nèi)核以及制作JFFS2文件系統(tǒng)。其中創(chuàng)新地提出了從nandflash啟動(dòng)U-BOOT具體設(shè)計(jì)方法。為了完成系統(tǒng)進(jìn)一步的視頻采集工作,系統(tǒng)實(shí)現(xiàn)了USB數(shù)碼攝像頭的驅(qū)動(dòng)。在應(yīng)用程序開發(fā)過程中,首先設(shè)計(jì)了基于Vide04Linux的視頻采集程序,并采用mmap(內(nèi)存映射)方式截取圖片。其次重點(diǎn)分析了MPEG-4編碼模型XVID程序中的運(yùn)動(dòng)估計(jì)部分,并研究了半像素快速搜索算法,從而減少了搜索點(diǎn)數(shù)提高了運(yùn)算速度。最后利用開源JRTPLIB庫實(shí)現(xiàn)視頻數(shù)據(jù)流的RTP傳送。 整個(gè)設(shè)計(jì)都是在深圳旋極公司研制的SUPER-ARM硬件平臺(tái)上進(jìn)行的,linux內(nèi)核采用2.4.18。其中MPEG-4編碼優(yōu)化測(cè)試是在ARM DeveloperSuite(ADS)version 1.2中完成。 本課題為在ARM平臺(tái)實(shí)現(xiàn)網(wǎng)絡(luò)視頻監(jiān)控的設(shè)計(jì)做了有益的探索性嘗試,對(duì)今后進(jìn)一步完成遠(yuǎn)程嵌入式視頻監(jiān)控系統(tǒng)的設(shè)計(jì)有著積極的意義。

  • COOLMOS_原理結(jié)構(gòu)

    看到不少網(wǎng)友對(duì)COOLMOS感興趣,把自己收集整理的資料、個(gè)人理解發(fā)出來,與大家共享。個(gè)人理解不一定完全正確,僅供參考。COOLMOS(super junction)原理,與普通VDMOS的差異如下: 對(duì)于常規(guī)VDMOS器件結(jié)構(gòu),大家都知道Rdson與BV這一對(duì)矛盾關(guān)系,要想提高BV,都是從減小EPI參雜濃度著手,但是外延層又是正向電流流通的通道,EPI參雜濃度減小了,電阻必然變大,Rdson就大了。所以對(duì)于普通VDMOS,兩者矛盾不可調(diào)和。8 X( ?1 B4 i* q: i但是對(duì)于COOLMOS,這個(gè)矛盾就不那么明顯了。通過設(shè)置一個(gè)深入EPI的的P區(qū),大大提高了BV,同時(shí)對(duì)Rdson上不產(chǎn)生影響。為什么有了這個(gè)深入襯底的P區(qū),就能大大提高耐壓呢?

  • 了解模數(shù)轉(zhuǎn)換器的噪聲、ENOB

    Abstract: Specifications such as noise, effective number of bits (ENOB), effective resolution, and noise-free resolution inlarge part define how accurate an ADC really is. Consequently, understanding the performance metrics related to noise isone of the most difficult aspects of transitioning from a SAR to a delta-sigma ADC. With the current demand for higherresolution, designers must develop a better understanding of ADC noise, ENOB, effective resolution, and signal-to-noiseratio (SNR). This application note helps that understanding.

  • ADC中精確度與分辨率認(rèn)識(shí)

        ADC制造商在數(shù)據(jù)手冊(cè)中定義ADC性能的方式令人困惑,并且可能會(huì)在應(yīng)用開發(fā)中導(dǎo)致錯(cuò)誤的推斷。最大的困惑也許就是“分辨率”和“精確度”了——即Resolution和Accuracy,這是兩個(gè)不同的參數(shù),卻經(jīng)常被混用,但事實(shí)上,分辨率并不能代表精確度,反之亦然。本文提出并解釋了ADC“分辨率”和“精確度”,它們與動(dòng)態(tài)范圍、噪聲層的關(guān)系,以及在諸如計(jì)量等應(yīng)用中的含義。
