Abstract:
1. A method of managing power in a processing system, comprising: providing a single global maximum power consumption bound for a plurality of groups of devices within said processing system; determining associated local maximum bounds of power consumption, one for each of said plurality of groups of devices, wherein a sum of said local bounds is less than a global maximum power consumption bound; communicating each local maximum bound to an associated one of a plurality of local controllers coupled to said associated group of devices; within each of said associated local controllers, second determining power management states for each device within each of said associated group of devices consistent with said associated local maximum bound, whereby said global maximum power consumption bound is met by meeting all of said local bounds; and setting said power management state of each device in each of said plurality of groups from each of said associated local controllers.
