Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A method comprising: analyzing, in a logic of a multicore processor including a plurality of cores, a plurality of power state change events during an evaluation interval to determine a hypothetical number of frequency transitions responsive to the plurality of power state change events for each of N-core turbo frequencies; selecting one of the N-core turbo frequencies to be a maximum operating frequency of the multicore processor for a next operating inte…
