Abstract: In one embodiment, an apparatus includes: at least one processing circuit; at least one array associated with the at least one processing circuit; a power controller to manage power consumption of the apparatus; and a fabric bridge coupled to the power controller. The fabric bridge and power controller may be configured to implement a handshaking protocol to enable the fabric bridge to receive data from the at least one array via a sideband communication path and send the data to a system memory coupled to the apparatus via a primary communication path, prior to entry of the apparatus into a first low power state. Other embodiments are described and claimed.

Abstract: Embodiments of the invention relate to a method and apparatus for a zero voltage processor sleep state. A processor may include a dedicated cache memory. A voltage regulator may be coupled to the processor to provide an operating voltage to the processor. During a transition to a zero voltage power management state for the processor, the operational voltage applied to the processor by the voltage regulator may be reduced to approximately zero and the state variables associated with the processor may be saved to the dedicated cache memory.
