摘要: 针对JFFS2文件系统挂载时间过长、占用系统内存过多的缺点,提出一种基于NAND闪存芯片的文件系统。借鉴JFFS2和磁盘文件系统的相关方法,介绍挂载实现过程。挂载测试结果表明,该系统的装载性能高于JFFS2文件系统,具有合理性和可行性。

Abstract: Aiming at the drawbacks that a long mount time and a large RAM disappear in JFFS2 file system, this paper proposes file system based on NFFS Flash chip. It uses JFFS2 and disk file systems for reference, expatiates the mount process and its implementation. Mount test results show that this system has higher loading performance than JFFS2 file system. It is reasonable and feasible.

Key words: Flash, file system, NAND chip, mount
