The Structure and Implementation of Journaling File System on Embedded System

Speed and reliability are the most important performances of file system. However, problems still occur due to the hardware, software or power failures. Since there is not any existed research or implementation of journaling file system on the embedded systems, the paper introduces how to implement journaling file system on resource constrained system and concludes the common structure of FS on embedded system. Finally, it put forwards on how to minimize the code and speed up the performance.
