摘　　要：在嵌入式设备中,文件系统的实现及良好应用是系统功能实现的关键部分之一。从Flash闪存设备特点和车载导航仪功能出发,在分析了几种文件系统各自的优缺点之后,基于ARM处理器S3C2410和嵌入式Linux操作系统平台设计了一种多文件系统,并详细介绍了该多文件系统的实现方法。通过原型机的反复调试,证明该文件系统是可行的和合理的,可以性能满足系统要求。The realization and well application of file system is one of the key partitions to implement the system function in embedded devices. Considering the characteristics of the flash device and the functions of the car-navigation system,the authors analyzed some embedded file systems-Tmpfs,Cramfs and YAFFS, then designed a multi-file system based on ARM microprocessor S3C2410 and embedded linux. This paper describes the details of the method to realize the multi-file system. Through repeated testing in a prototype, it is proved that the file system is feasible and reasonable, and its performance meets the system requirements.
