Abstract
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.
