| Abstract: | Reducing the power of storage system is an important goal in SoC design. Based on the analyses of program and device, this paper proposes a method for this goal. This method introduces data buffer in SDRAM in order to reduce the power of external memory in the environment of multi-process and instruction FIFO in EMI is implemented in order to reduce the energy consumed by SDRAM when program is running. Results of experiment and simulation showed that this method can reduce the overall power of SoC storage system when program is running. |
