摘要
开发了一个基于闪存平台的嵌入式文件系统。为保证闪存扇区的平均使用率和均衡擦写次数,引入了损坏管理策略,在这种策略中采用了动态存储空间管理模式和先入先出(FIFO)策略。所采用的冗余设计、快速计算和跟踪策略还可以延长核心扇区使用寿命,保证系统启动可靠的服务。
In this paper, a specified file system adapted to embedded system with flash-based memory is developed. To guarantee the average usage of flash storage sectors, the strategy of wear leveling and adaptive damage management is introduced, in which a dynamic storage space management mode and the strategy of first in first out （FIFO） are adopted. Moreover, the strategy of redundancy design and fast-calculation and tracing is also adopted to extend the life of kernel sector, which can guarantee the reliable ser-vice of system booting.
