20090150695 | Predicting future power level states for processor cores - In one embodiment, the present invention includes a method for providing power state change information from a plurality of cores of a processor package to a predictor at a periodic interval and generating a prediction to indicate a predicted operation level of the cores during a next operating period. Other embodiments are described and claimed. | 06-11-2009 |
20090150696 | Transitioning a processor package to a low power state - In one embodiment, a processor package is controlled to be in a package low power state for a first portion of an operation interval and in a package active state for a second portion of the operation interval. To enable the low power state, operations scheduled during the first portion are delayed until the second portion. Other embodiments are described and claimed. | 06-11-2009 |
20090172423 | METHOD, SYSTEM, AND APPARATUS FOR REROUTING INTERRUPTS IN A MULTI-CORE PROCESSOR - A method, system, and apparatus may route an interrupt to a first core of a plurality of cores of a multi-core system. If the first core is in an idle or low power state, or operating in a power state at or below a threshold power state, a core in a least idle state may be found. The interrupt may be rerouted to and processed by the core in the least idle state. Cores in a multi-core system may be rated based on for example, power states or other characteristics, and interrupts may be assigned based on these ratings. Other embodiments are described and claimed. | 07-02-2009 |
