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 programs. Experimental results show that this approach can save nearly 70% power with negligible performance degradation.
