摘 要
 隨著電子技術(shù)的快速發(fā)展，特別是大規(guī)模集成電路的產(chǎn)生而出現(xiàn)的微型機(jī)，使現(xiàn)代科學(xué)研究得到了質(zhì)的飛躍，而嵌入式微控制器技術(shù)的出現(xiàn)則是給現(xiàn)代工業(yè)控制領(lǐng)域帶來了一次新的技術(shù)革命。由嵌入式微控制器組成的系統(tǒng)，最明顯的優(yōu)勢就是可以嵌入到任何微型或小型儀器、設(shè)備中。隨著嵌入式設(shè)備與Internet的廣泛地結(jié)合，手機(jī)、PDA、路由器和調(diào)制解調(diào)器等復(fù)雜的高端應(yīng)用對嵌入式處理器的性能提出了更高的要求，因此開發(fā)32位高性能處理器將是嵌入式技術(shù)發(fā)展的必然趨勢。本論文的設(shè)計(jì)主要采用ARM芯片編程設(shè)計(jì)FAT12文件系統(tǒng)操作函數(shù)，該操作函數(shù)可以用于對文件的管理。系統(tǒng)選用飛利浦公司的ARM7芯片LPC2214來設(shè)計(jì)一套嵌入式的文件系統(tǒng)。主要實(shí)現(xiàn)對文件的管理和各函數(shù)間的調(diào)用功能，包括格式化，打開，關(guān)閉，讀，寫，建立，刪除，查找，列舉目錄下的文件等功能。本論文主要介紹了以上相關(guān)部分軟件的設(shè)計(jì)。

Abstract
 Along with the electronic technology fast development, with the large scale integrated circuit technology development the miniature machine  appears, which make the modern scientific research obtain great leap. Meanwhile the appearance of embedded controller technology has brought a new technological revolution in modern industry control field. The most obvious superiority in system composed of embedded controller is may be inserted to any miniature or small instruments and equipments. Along with the widely combination of embedded system and Internet, the complex  application  in mobile phone, PDA, router and modem etc put forward a higher demand on the performance of embedded processor, therefore developing 32-bit high performance processors will be a inevitable trend. This dissertation mainly use the ARM chip to design the FAT12 file system operation functions, these operation functions may be used in file management. In this system the Phillips ARM7 chip LPC2214 is used to design a embedded file system, which carry out the document management and various calling among different functions. These functions include formatting、opening、closing、reading、 writing、creating and so on. This dissertation mainly introduced the partial software design above mentioned.
