摘要: 由于运行环境及存储硬件特性的差异,PC机的文件系统不适合直接用于嵌入式系统中数据内容的存储和管理。针对数控系统对零件加工程序进行管理的需求,提出了适于嵌入式系统应用的文件系统。该文件系统采用Flash扇区均衡损耗策略,并具有坏损扇区自适应管理特性,对于使用Flash作为存储介质的嵌入式系统具有一定的普适性。

关键词: 文件系统, Flash存储器, 嵌入式系统

Abstract: General file system of PC can seldom work properly when it comes to embedded platform.This is mainly because differences between PC and embedded platform,like working condition,storage hardware characteristic,etc.To meet managing requirement of machining workpiece program in numerically controlled system,a new file system adapt to embedded system is put forward in this paper.A strategy of equalizing abrasion of Flash sectors is applied.With this file system,damaged Flash sectors can be dealt automatically.It can be generally applied to embedded systems with Flash storage media.

Key words: file system, Flash storage, embedded system
