嵌入式Linux混合文件系统的设计与分析

A Research of hybrid root File-System of Embedded Linux

嵌入式Linux系统必须达到性能和空间的优化。文章对嵌入式Linux进行了耗时分析,根据系统对根文件目录操作中耗时问题设计了嵌入式Linux混合文件系统,并与常见单一文件系统在启动速度和程序运行速度上对其进行了仿真测试。数据证明混合型文件系统不仅占用空间较小,并且能提高系统的性能。

Performance and size must be balanced in Embedded Linux to get a low usage of memory and high speed.The paper present a hybrid root file-system based on MTD device which combined CRAMFS and JFFS2,by comparing the boot time of Linux and performance with single root file- system,the size is small and the boot time decreased.It could be helpful in the field of Linux root File-System.
