摘要： 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.

摘要： In one embodiment, the present invention includes a multicore processor with a power controller to control a frequency at which the processor operates. More specifically, the power controller can limit a maximum operating frequency of the processor to less than a configured maximum operating frequency to enable a reduction in a number of frequency transitions occurring responsive to power state events, thus avoiding the overhead of operations performed in handling such transitions. Other embodiments are described and claimed.

摘要： In one embodiment, the present invention includes a method for determining, in a controller of a multi-domain processor, whether a temperature of a second domain of the multi-domain processor is greater than a sum of a throttle threshold and a cross-domain margin, and if so, reducing a frequency of a first domain of the multi-domain processor by a selected amount. In this way, a temperature of the second domain can be allowed to reduce, given a thermal coupling of the domains. Other embodiments are described and claimed.
