摘要: 嵌入式系统需要处理大容量数据,其存储介质具有多样性。该文提出一种遵循FAT标准、能在多种介质上移植的嵌入式文件系统(EFS)。分析EFS的体系结构,给出底层驱动的设计方法。实验结果表明,EFS支持FAT12/16/32格式文件且可靠性高,它采用模块化设计,提供标准API函数,具有较高可移植性。该系统已应用于实际产品中。

Abstract: Mass data processing and variety of memory medium is existed in the embedded system. This paper designs an Embedded File System(EFS) is which followed by the File Allocation Table(FAT) specification and can be transplanted to variety of the medium. It analyzes the system structure of EFS and lists the bottom-driven design method based on it. Experimental results show that EFS supports FAT12/16/32 format, has high reliability, and adopts modular design to provide standard API function so that it can be transplanted easily. This system is used in the actual products.
