A New Type of Embedded File System Based on SPM

摘要

Commonly, embedded file systems reside in main memory to manage the external memory such as flash memory in embedded systems. With the progress of hardware of embedded systems, the gap of speed between main memory and CPU is becoming larger and larger. The traditional embedded file systems can not be able to support real-time response enough for their main memory management policy. A new type of embedded file system is presented to provide more real-time performance. This new embedded file system, SPM file system, is based on the internal SRAM on chip and is able to reduce response time.
