嵌入式Linux文件系統(tǒng)的研究與應(yīng)用

隨著嵌入式系統(tǒng)的發(fā)展，使用Linux操作系統(tǒng)搭建的嵌入式平臺得到了越來越廣泛的應(yīng)用。文件系統(tǒng)是嵌入式Linux 系統(tǒng)的重要組成部分，一個合適的文件系統(tǒng)解決方案可
以極大的提高系統(tǒng)的性能并充分利用系統(tǒng)資源。本文介紹了幾種常用的嵌入式Linux 文件系統(tǒng)，在對其優(yōu)缺點進行分析的基礎(chǔ)上，提出了一種兼顧系統(tǒng)安全性與靈活性的文件系統(tǒng)解決方案，并詳細說明了實現(xiàn)該方案的具體步驟。

Abstract : With the development of embedded system， the embedded platform using
Linux has got more and more extensive application. The file system is the important
component of an embedded Linux system, and a suitable file system may greatly improve
system’s performance and fully utilize system’s resources. In this paper, we introduce
several kinds of common file systems used in embedded Linux and analyze its advantage
and shortcoming. Then we have proposed a kind of solution which can give consideration
to system’s security and flexibility at the same time. In the end, the detailed steps of
finishing the scheme are interpreted.
