Abstract :
A flash storage system based on cable modem is implemented. On the hardware hand, a flash controller is designed using cache and queue technology, and realizes burst read from flash by a simple set associative cache, and implements asynchronous write to flash by FIFO queue. On the software hand, we revise CFI on MTD so that flash access processes are scheduled by the way of interrupt instead of continuous queries. Performance analysis and test result show that the system improves access efficiency of flash and throughput of CPU, with a high stability and flexible configurability. The system has been used for cable modem based on Godson-I CPU. With generality, it can be used for correlative embedded systems.
