Abstract:
A technique to retain cached information during a low power mode, according to at least one embodiment. In one embodiment, information stored in a processor's local cache is saved to a shared cache before the processor is placed into a low power mode, such that other processors may access information from the shared cache instead of causing the low power mode processor to return from the low power mode to service an access to its local cache.
