摘要
  
本嵌入式Web服務(wù)器基于Samsung S3C44B0X處理器實(shí)現(xiàn)了一個(gè)“瘦”服務(wù)器；由于其“瘦”，因而可“植入”其它受控系統(tǒng)后接入Internet，從而使得任何地方的計(jì)算機(jī)均可通過(guò)瀏覽器訪問(wèn)該Web服務(wù)器發(fā)布的實(shí)時(shí)信息，進(jìn)而實(shí)現(xiàn)遠(yuǎn)程控制與維護(hù)。由于此類(lèi)嵌入式Web服務(wù)器降低了開(kāi)發(fā)費(fèi)用、通信費(fèi)用以及后期的升級(jí)維護(hù)費(fèi)用，因此具有極為廣泛的應(yīng)用前景。
本論文作為嵌入式web服務(wù)器的一部分，主要負(fù)責(zé)實(shí)現(xiàn)嵌入式實(shí)時(shí)操作系統(tǒng)UC/OS-II的移植及RTL8019網(wǎng)卡驅(qū)動(dòng)程序的實(shí)現(xiàn)。
首先，本文簡(jiǎn)單介紹了Samsung S3C44B0X處理器的基本原理，以及硬件開(kāi)發(fā)平臺(tái)的結(jié)構(gòu)及與設(shè)計(jì)相關(guān)的資源。      
其次，本文詳細(xì)闡述了RTL8019網(wǎng)卡的結(jié)構(gòu)及工作原理，以及驅(qū)動(dòng)程序的具體實(shí)現(xiàn)。
再次，本文簡(jiǎn)要論述了嵌入式實(shí)時(shí)操作系統(tǒng)UC/OS-II的結(jié)構(gòu)后，重點(diǎn)介紹了UC/OS-II在Samsung S3C44B0X處理器上移植辦法。
最后，本文對(duì)操作系統(tǒng)的移植及驅(qū)動(dòng)程序的實(shí)現(xiàn)兩部分進(jìn)行測(cè)試，經(jīng)檢測(cè)，表明操作系統(tǒng)的移植成功，網(wǎng)卡RTL8019能實(shí)現(xiàn)底層數(shù)據(jù)的傳送。

 Abstract

The embedded Web server was realized as a 'thin server” based on Samsung S3C44B0X processor.  It could make the controll system that it embedded into has the ability to connect to the internet acting as a web server, and the computers in any places could visit this real-time information published by the embedded web server through a web browser. Then, remote control and safeguard could take with it. It could be in wildly use as embedded Web server can reduce development expenses, communication expenses and back-end upgrading maintain expenses.   This article present a transplantation of a real-time operation system μC/OS to the develop board based on S3C44B0X microprocessor and realized a network adapter driver of RTL8019.
 In this article, the basic principle of Samsung S3C44B0X processor, the structure of the hardware developing platform and the resource correlated this design were introduced firstly. Secondly, the structure of the RTL8019 network adapter and operation principle, and the correct realization of drive procedure were explained in detail.Thirdly, after brieftly expounding the structure of UC/OS-II,we have introduced the μC/OS-II, the transplanted on Samsung S3C44B0X processor was especially expressed. Finally, the embedded web server was tested, which indicated that the success of this design. Key words：ARM，Web server，UC/OS-II，RTL8019
