摘要
为了在嵌入式系统上建立通用的Flash文件系统,以Vxworks操作系统为基础,对Flash文件系统的概念以及存储管理方式进行了深入研究,并对商业化产品TrueFFS文件系统的体系结构以及回收和磨损控制算法的可实现性和使用效率等进行了详细分析,针对TrueFFS的磨损控制算法,使用线性预测取平均法证明了该算法有较强的实用性和可行性.
In order to develop Flash file system on embedded system, based on the Vxworks, the authors focus on the concept and memory management of Flash file system. The architecture of TrueFFS file system and the feasibility of the system reclaiming and wear-leveling algorithms are discussed in detail. By using linear average method, the wearing leveling algorithm is proved to be feasible.
