The Implementation of Journaling File System on Embedded Memory Device
日志文件系统在嵌入式存储设备上的实现

In embedded systems,unexpected power-off often causes the corruption of the file system and the lose of data.It is necessary to develop a special kind of file system to prevent such corruption.As a kind of journaling file system specially for embedded memory devices,JFFS is just the files system we need.In order to make use of JFFS more extensively,Redfiag Software Ltd.Co.has successfully soved the problem about JFFS‘‘‘‘‘‘‘‘ implementation on DiskOnChip,a special kind of embedded memory device.This paper mostly discusses the design of JFFS and its implementation on DiskOnChip.
