摘要
JFFS2 (Journaling Flash File System, version 2)是Linux平台上一种流行的文件系统，用于管理NAND型闪存，简称NandFlash。基于JFFS2机制，提出了一种有效的NandFlash管理方法，即NandFlash的新型flash文件系统NFFSNand。我们的方法侧重于以平衡的方式降低循环均衡度。此外，NFFSNand可以提高系统性能，延长NandFlash的生命周期。在本研究中，我们在三星SMDK2410X平台上验证了NFFSNand的系统成本、可靠性和空间利用率比JFFS2好50%
JFFS2 (Journaling Flash File System, version 2) is a popular file system of Linux platform that is employed to manage NAND type flash memory, briefly denoted by NandFlash. Based on JFFS2 mechanism, we propose an effective management method of NandFlash, new flash file system for NandFlash called NFFSNand. Our method focuses on reducing the cycle-leveling degree in a balanced manner. Moreover, NFFSNand can enhance the system performance and prolongs life-cycle of NandFlash. In this study, we verify the system cost, the reliability, and space utilization of NFFSNand are better than JFFS2 by 50% at Samsung SMDK2410X platform
