Smart File System: Embedded File System Based on NAND-Flash

摘要

With the prevalence of embedded system, especially mobile system, Flash-memory storage which has high capacity and low energy consumption has become the primary external storage for embedded systems. Some file system based on flash memory have been designed and implemented such as JFFS2 and YAFFS2. But they all have some defects: long boot time, high memory consumption and so on. In this paper, SmartFS (Smart File System) is presented and described. SmartFS can improve the performance of flash memory management and make good use of large capacity flash memory.
