We propose a novel hardware-based DVS technique called dynamic processor throttling (DPT) for power efficient computations. DPT focuses on the performance balance between the processor and main memory, When a performance imbalance is detected, DPT tries to redress the imbalance by setting the clock frequency and supply voltage of the processor to a well-balanced point. This paper describes the micro-architecture mechanisms of DPT and shows the evaluation results on energy saving and performance compared with a conventional cache-miss-driven DVS technique. The results reveal that DPT can reduce 17% of the energy with a 3.4% performance degradation and DPT surpasses the conventional technique in both performance and energy.
