This paper introduces the power management schemes that control DVFS (Dynamic Voltage and Frequency Scaling) and core shutdown considering the characteristics of an application for the commercial application processors. Most power management schemes used in commercial application processors only monitor the CPU utilization to adjust the CPU frequency. Since recent application processors adopt multi-core CPU, the power management scheme, such as Hotplug, is necessary to manage the power state of the cores. However, none of the schemes mentioned above looks into the application characteristics for the power management. In this paper, we show that considering application characteristics is more beneficial for power management of recent commercial application processors.
