摘要: 针对嵌入式系统资源有限、稳定性差的问题,通过分析现有文件系统的优缺点,提出一种面向大容量媒体文件的嵌入式文件系统设计方案,介绍其体系架构和内部组成,对该文件系统与传统嵌入式文件系统的存储性能及稳定性进行对比测试。实验结果表明,该文件系统在存储性能和稳定性方面具有较大优势。

关键词: 大容量媒体文件, 嵌入式存储, 存储结构, 存储性能

Abstract: By analyzing the advantages and disadvantages of the existing file systems, aiming at the limited resources and poor stability characteristics of embedded file systems, this paper puts forward a new large-capacity file storage structure named MSFS(M Structure File System). It introduces the file system architecture and internal composition, tests reading and writing performance and makes comparison with the traditional and common file systems based on embedded system. Experimental results show the advantages of MSFS in storage and stability.

Key words: large-capacity media file, embedded storage, storage structure, storage performance
