A local power control arbiter is provided to interface with a global power control unit of a processing platform having a plurality of processing entities. The local power control arbiter controls a local processing unit of the processing platform. The local power arbiter has an interface to receive from the global power control unit, a local performance limit allocated to the local processing unit depending on a global power control evaluation and processing circuitry to determine any change to one or more processing conditions prevailing in the local processing unit on a timescale shorter than a duration for which the local performance limit is applied to the local processing unit by the global power control unit and to select a performance level for the local processing unit depending on both the local performance limit and the determined change, if any, to the prevailing processing conditions on the local processing unit.

Power control arbitration

A method and apparatus for performing current control for an integrated circuit are described. In one embodiment the apparatus comprises core logic coupled to receive a first current; a clock generator to generate a first clock signal; and a closed loop current controller coupled to the clock generator and coupled to provide a second clock signal to the core logic based on the first clock signal, the current controller to control an amount of the first current received by the core logic by changing the first clock signal to generate the second clock signal.

Current sensor based closed loop control apparatus

Described herein are apparatus, system, and method for providing clock signal on demand. The method comprises determining an indication of clock signal usage in multiple hardware logic units; generating an enable signal according to the indication; and gating or un-gating the clock signal for clock islands of at least a hardware logic unit, of the multiple hardware logic units, in response to a logic level of the enable signal, wherein the clock islands are part of a global clock distribution network and are operable to be enabled or disabled independently.
