摘要

文件分配表(File Allocation Table, FAT)文件系统是一种广泛应用于平板个人电脑、移动电话、数码相机等嵌入式设备的文件系统，用于数据存储和视频成像、音频/视频回放和录制等多媒体应用。FAT文件系统不是电源故障安全的。这意味着，不受控制的断电或突然从计算机/嵌入式系统中移除存储设备会导致文件系统损坏。TFAT(事务安全FAT)文件系统是FAT文件系统的扩展，为FAT文件系统提供电源故障安全功能。本文通过在Windows CE (Compact Embedded) 6.0操作系统中对文件系统操作进行各种组合，探讨了TFAT文件系统集群分配算法的设计方法。本文还记录了TFAT文件系统与FAT文件系统的性能基准测试。

Design Methodologies of Transaction-Safe Cluster Allocations in TFAT File System for Embedded Storage Devices

The File Allocation Table (FAT) file system is widely used file system in tablet personal computers, mobile phones, digital cameras and other embedded devices for data storage and multi-media applications such as video imaging, audio/video playback and recording. The FAT file system is not power fail-safe. This means that, the uncontrolled power loss or abrupt removal of storage device from computer/embedded system causes the file system corruption. The TFAT (Transaction safe FAT) file system is an extension of FAT file system to provide power fail-safe feature to the FAT file system. This paper explores the design methodologies of cluster allocation algorithms of TFAT file system by conducting various combinations of file system operations in Windows CE (Compact Embedded) 6.0 Operating System (OS). This paper also records the performance bench-marking of TFAT file system in comparison with FAT File system.
