System identification and energy-aware processor utilization control

Abstract

Minimization of power consumption is essential for battery-powered computing systems. This paper proposes an innovative solution for the processor power management problem. The proposed technique does not require accurate power consumption and performance model of the processor. The proposed solution exploits feedback control principles and the controller design is optimized for a given workload. Experimental results obtained from a case study are presented demonstrating, usefulness and the feasibility of the proposed solution.
