嵌入式Flash文件系统的设计与实现

Flash存储器是一种在嵌入式系统中日益普及的存储介质，它提供了高密度且成本相对较低的固态存储。使用Flash存储器需要很多技巧来确保数据可靠性并延长Flash器件的使用寿命。根据Flash存储器的特点提出了一种文件系统模型，可以合理且有效地利用Flash存储器，同时提供日志特性以增强使用该文件系统的嵌入式系统的可靠性。

Design and Implementation of Embedded Flash File System

Flash memory is an increasingly common storage medium in embedded devices. It provides solid state storage with high density at a relatively low cost. The usage of flash memory needs many techniques to provide reliability of data and to prolong the lifetime of flash devices. Based on the characteristics of flash memory, a file system model is put forward. This model can take advantage of flash memory reasonably and efficiently. It can also provide journalling features to enhance the reliability of embedded systems who use the file system.
