通过分析闪存日志文件系统JFFS3的基本设计文档,提出了改进JFFS3设计的方案,包括对索引节点进行压缩存储,引入数据冷热性的概念,有效提高了JFFS3磨损平衡机制的效率,同时对正处于设计阶段的垃圾回收机制提出了适用的方案和算法。
The Joumalling Flash File System version 3 design issues was analyzed and some solutions, Including compression of index nodes and importing the conception of the cold and hot data to improve the efficiency of wearleveling, was put forward. Proper proposals and arithmetic for Garbage collecting are also given which now is under designing.
