摘　　要：事务型文件系统可跟踪文件系统最终的稳定状态,保证在掉电环境下仍可正常工作。针对铁电存储器的特点,给出基于铁电存储器事务型文件系统的设计方案、底层驱动及应用接口设计,并对基于不同存储器的事务型文件系统进行性能比较。实验结果表明,基于铁电存储器的事务型文件系统文件管理方便、写入速度快,同时数据存储不受突发断电的影响,无需在重启时进行冗长的磁盘检测,降低了应用程序编写难度,加快了重启时间。The transactional file system can keep track of the final steady state of the file system to ensure that in any power loss environment it can still work correctly. Given the characteristics of the FRAM transactional file sys- tem design, the driver and application interface designs are given, and a comparison in performance is made of dif- ferent memory-based transactional file systems. Experiments show that the our design enjoys easy management and fast write speed, protects critical system and user data from corruption in case of power failure, saves the need to re- start the lengthy disk detection, reduces the difficulty of application programming, and speeds up the restart.
