摘要 介绍一种嵌入式文件系统模型,并将其应用于基于嵌入式系统的高速记录设备中。模型具有简捷、可靠、灵活性高等特点。对记录器存储介质的特点及文件系统的要求进行分析,详细介绍由软核NiosⅡ管理的文件系统模型。模型借鉴通用FAT文件系统的设计理念,并进行针对性的精简,同时加强了数据的可靠性管理,打破了线性文件系统的管理模式,允许文件随机存取,可以很方便地移植到其它嵌入式应用中。 A type of embedded file system model used in the high speed record equipment based on the embedded system is realized in this paper. The file system is sententious,reliable and flexible. This paper firstly analyzes and studies the characteristics of recorder memory medium and the requirement of file systems,and then introduces the file system model managed by Nios Ⅱ. Themodel uses the FAT design principle for reference,simplifies the FAT aiming at the recorder application,and enhances the reliable management of data. The model disaccustoms the management mode of linear file system. It is random-access,and can be transplanted to other embedded application expediently.
