Towards platform level power management in mobile systems Conference Paper uri icon


  • © 2014 IEEE. This paper presents a platform-level power management framework for mobile platforms. The proposed framework minimizes the overall platform energy while meeting system level performance and power budget constraints. To this end, we construct analytical performance and power models using dynamic information collected via performance monitoring counters. Using these models, we design two different closed loop controllers to ensure that both the performance and the power targets are achieved and maintained in the presence of dynamic workload variations. Experimental evaluations performed on an Android platform show up to 8% energy savings at the platform level and up to 15% CPU energy savings.
