International Classification:

G06F 9/318
US Classification:

712 30, 712E09035
Abstract:

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.
