A power-aware LLC control mechanism for the 3D-stacked memory system

Aiming at improving the energy efficiency of 3D-stacked memory subsystems, this paper proposes a power-aware last level cache (LLC) control mechanism. The proposed mechanism switches enabling/disabling the LLC according to application characteristics and the power efficiency of the memory subsystems...

Summary:Aiming at improving the energy efficiency of 3D-stacked memory subsystems, this paper proposes a power-aware last level cache (LLC) control mechanism. The proposed mechanism switches enabling/disabling the LLC according to application characteristics and the power efficiency of the memory subsystems. Evaluation results show that the proposed mechanism improves the power efficiency of 3D-stacked memory subsystems by up to 25%, and 11% on average.
