| Abstract: | Storage management strategy can be expressed by a file system. Commercial file system for embedded application is generally
complicated and resource wasted. In this paper, a specified file system adapted to embedded system with flash-based memory
is developed. To guarantee the average usage of flash storage sectors, the strategy of wear leveling and adaptive damage management
is introduced, in which a dynamic storage space management mode and the strategy of first in first out (FIFO) are adopted.
Moreover, the strategy of redundancy design and fast-calculation and tracing is also adopted to extend the life of kernel
sector, which can guarantee the reliable service of system booting. The practical application in an embedded CNC (computerized
numerical control) platform proves that the file system has effective performance. Furthermore, the flash file system can
be transplanted to different embedded platforms by changing a few bottom hardware parameters with universality. |
