| Abstract(in English) | This paper proposes a dynamic management technique of Non-uniform Selective Way Cache (NSWC) for reducing the total energy consumption of a CPU core, cache memories, and off-chip memories. NSWC has a way uses low supply (Vdd) and low threshould (Vth). In our approach, we decide insert points of instructions to change available ways in the Non-uniform Selective Way Cache. Experiments using parameters of a commercial embedded processor and an off-chip SDRAM demonstrate that our algorithm reduces the energy consumption of the processor system by 7%-20% compared to the result of a processor with a same size set associative cache memory. |
