Power management for multiple processor cores

Abstract

Methods and apparatus relating to power management for multiple processor cores are described. In one embodiment, one or more techniques may be utilized locally (e.g., on a per core basis) to manage power consumption in a processor. In another embodiment, power may be distributed among different power planes of a processor based on energy-based considerations. Other embodiments are also disclosed and claimed.

1 . An apparatus comprising:
 a processor having a plurality of processor cores;   a single power plane to supply power to more than one of the plurality of processor cores; and   a power management logic to cause a modification to an operational characteristic of at least one processor core of the plurality of processor cores in response to:
 a detection of excessive temperature at the least one processor core; and 
 a determination of which one of the other processor cores of the plurality of processor cores are active and at a temperature value.
