Abstract
Power management systems and methods that facilitate efficient and effective power conservation are presented. In one embodiment a power management method comprises: performing an initiation metric determination process, and adjusting operations of a logic component based on said threshold value. In one exemplary implementation, the initiation metric determination process includes monitoring activity of a logic component, and establishing a power conservation initiation threshold value. The initiation metric determination process can include performing a system architecture characteristic analysis in which a system architecture power-consumption break-even time (BE) is determined for the system. The initiation metric determination process can also include performing a system utilization analysis process is performed in which idle period durations detected during said monitoring are sorted into a variety of different length intervals and analyzed accordingly. Histograms of idle period durations can be collected. Adjusting operations can include entering a low power state.

7. A system of power management comprising:
-
a monitoring component that tracks power usage; a threshold determining component, included in a processor, that establishes a threshold based on said power usage, wherein the threshold value includes examining the probability that initiating a power reduction operation saves more power than a power cost of entering and existing a power reduced state; and a power control component that directs power consumption state adjustment of an electronic component based on said threshold. - View Dependent Claims (8, 9, 10, 11, 12, 13)
