Requester-aware power reduction

Typically, power reduction is conducted by hardware techniques, such as varying clock frequencies and/or supply voltages. However, hardware devices consume power to serve the requests from software programs. Consequently, it is essential to consider software for power reduction. This paper proposes “requester-aware” power reduction through the collaboration with pro-grams. Experimental results show that this approach can save nearly 70 % power with negligible performance degradation. 1
