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.

In an embodiment, a processor includes at least one functional block and a central power controller. The at least one functional block may include at least one block component and block power logic. The block power logic may be to: receive a first request to initiate a first reduced power mode in the at least one functional block, and in response to the first request, send a notification signal to a central power controller. The central power controller may be to, in response to the notification signal: store a first state of the at least one functional block, and initiate the first reduced power mode in the at least one functional block. Other embodiments are described and claimed.

A system and method is provided for establishing safe processor operating points. Some embodiments may include a tamper resistant storage element that stores information regarding one or more operating points of an adjustable processor operating parameter. Some embodiments may further include an element to determine what the current processor operating point is of the operating parameter, and an element to compare the current operating point of the operating parameter with the stored information.

A processor, system, and method are disclosed. In an embodiment, the processor includes a first site and a second site. There is a link to transmit a voltage stabilization signal from the second site to the first site. In the first site voltage correction logic can dynamically modify a voltage supplied to the first site and second site. In the second site there is logic to assert the voltage stabilization signal. After asserting the voltage stabilization signal, the second site is granted at least a window of time in which the supplied voltage to the second site does not change.

A method, device, and system are disclosed. In one embodiment the method includes supplying a processor with a first voltage. The method also includes allowing the processor to function within an enhanced processor halt state at the first voltage. The first voltage is a voltage below the lowest compatible voltage for the enhanced processor halt state. The method allows the processor to execute instructions upon waking from the enhanced processor halt state at the first voltage by throttling a maximum throughput rate of instructions being executed in the processor.

Embodiments of the invention relate to a method and apparatus for a zero voltage processor sleep state. A voltage regulator may be coupled to a 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 while an external voltage is continuously applied to a portion of the processor to save state variables of the processor during the zero voltage management power state.

A method and apparatus automatically transferring to an enhanced low-power state of a processor is disclosed. In one embodiment, either all or a portion of a processor core clock distribution grid may be powered down in these enhanced low-power states. In one embodiment, the processor may operate in a reduced power supply voltage and operate at a reduced frequency during these enhanced low-power states. In one embodiment, a portion of the clock distribution grid may be left on to support snoop operations at a reduced frequency.
