Abstract:

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 system design,the driver and application interface designs are given,and a comparison in performance is made of different 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 restart the lengthy disk detection,reduces the difficulty of application programming,and speeds up the restart.

Key words: ferroelectric nonvolatile RAM;transactional file system;TrueFFS;Flash
