Abstract
In one embodiment, the present invention includes a method for determining if a core of a multicore processor is in a low power state, and if so, estimating a temperature of the core and storing the estimated temperature in a thermal storage area for the first core. By use of this estimated temperature, an appropriate voltage at which to operate the core when it exits the low power state can be determined. Other embodiments are described and claimed.
