Dynamic Power Management Using Feedback
Overview The increasing speed and complexity of the microprocessor has brought about a corresponding increase in power consumption. Coupled with relatively small gains in battery capacity over recent years, the importance of intelligent battery management has become paramount. This paper presents a mechanism that takes advantage of feedback about power consumption in order to use battery energy more effectively. This feedback mechanism allows the implementation of many different energy management policies. One such policy is presented here which allows to direct power consumption by changing performance states in the scheduler to achieve predetermined energy goals. Furthermore, the implementation in Linux can synthesize any average power usage rate with little overhead.
