Patent ID: 7861102

Claim:
A power management system for providing a unified power management of at least one electronic system in a selected environment, the at least one electronic system includes a plurality of electronic components comprising: a first controller module operating at the at least one electronic system in the selected environment to generate a first power control of the each electronic component based at least on a system power budget for the at least one electronic system; a second controller module operating at each of the electronic components to generate a second power control of the each electronic component based at least on a component power budget for the each electronic component; a third controller module operating at each of the electronic components to modify a power-performance state of the each electronic component based on a target resource utilization level, wherein the target resource utilization level is based at least on the first and second power controls; and one or more interfaces operating to provide information exchange and coordination of control across at least the first, second, and third controller modules, wherein some of the electronic components in the at least one electronic system are enclosed in a subsystem of the at least one electronic system, and the power management system further comprises: a fourth controller module operating at the subsystem to provide a third power control of each of the electronic components in the subsystem based at least on a subsystem power budget for the subsystem.
