摘要:
A voltage regulator that is to change its DC output voltage as a primary function of a dynamic portion of integrated circuit (IC) supply current, wherein the voltage regulator's voltage dependence on at least one of a) IC supply leakage current, b) IC supply fixed dock current, or c) load current external to the IC, is a secondary and weaker function. Other embodiments are also described and claimed.
摘要:
While firing a number of phases of a multi-phase switching voltage regulator in a sequence, a determination is made as to which one of the phases has the lowest phase current. Then, the next phase, to be fired in the sequence, is selected as the one that has been determined to have the lowest phase current. Other embodiments are also described and claimed.

摘要:
Methods and apparatuses provide voltage regulation for a processor. Control or configuration parameters for a voltage regulator (VR) are provided digitally over a configuration bus to a VR controller. The parameters may be provided directly from a storage element, or via a processing element or processor core. Based in whole or in part on the parameters, the VR controller provides an output control signal to affect a power output from a power converter to the processing element. In one embodiment, the VR controller is integrated onto the same IC as the processing element.

摘要:
Methods and apparatus to improve integrated circuit (IC) performance across a range of operating conditions and/or physical constraints are described. In one embodiment, an operating parameter of one or more of processor cores may be adjusted in response to a change in the activity level of processor cores (e.g., the number of active processor cores) and/or a comparison of one or more operating conditions and one or more corresponding threshold values. Other embodiments are also described.
