摘要： 采用以页为单位的文件节点存储形式和综合考虑数据时间局部性与均衡磨损要求的收益成本垃圾回收算法,设计了一种新的文件系统。分析和实验表明,相对于JFFS2,该文件系统在降低内存消耗和闪存磨损倾斜度的同时,提高了垃圾回收效率和系统性能。

Abstract: A new file system devising page-unit storage format for files is proposed. A benefit-cost algorithm for garbage collection considerin temporal locality and wear leveling is also presented. Measurements demonstrate that contrasting with JFFS2, this file system improves garbag collection efficiency and system performance while reducing the footprint and leveling the worn-out.
