    摘要: In an embodiment, a processor includes a first processor core, a second processor core, a first voltage regulator to provide a first voltage to the first processor core with a first active value when the first processor core is active, and a second voltage regulator to provide a second voltage to the second processor core with a second active value when the second processor core is active. Responsive to a request to place the first processor core in a first low power state with an associated first low power voltage value, the first voltage regulator is to reduce the first voltage to a second low power voltage value that is less than the first low power voltage value, independent of the second voltage regulator. First data stored in a first register of the first processor core is retained at the second low power value. Other embodiments are described and claimed.

    摘要: A method and apparatus for atomic frequency and voltage changes in the processor. In one embodiment of the invention, the atomic frequency and voltage changes in the processor is feasible due to the enabling technology of fully integrated voltage regulators (FIVR) that are integrated in the processor. FIVR allows independent configuration of each core in the processor and the configuration includes, but is not limited to, voltage setting, frequency setting, clock setting and other parameters that affects the power consumption of each core.

    摘要: In an embodiment, a processor includes multiple cores each to independently execute instructions and a power control unit (PCU) coupled to the cores to control power consumption of the processor. In turn, the PCU includes a control logic to cause the processor to re-enter a first package low power state responsive to expiration of an inter-arrival timer, where this expiration indicates that a time duration subsequent to a transaction received in the processor has occurred. Other embodiments are described and claimed.

    摘要: Techniques to cause a point-to-point link between system components to engage in a negotiation process that may lead to the link transitioning from an active state in which data may be transmitted between system components to a low power state where data may not be transmitted. The negotiation process may occur between each pair of nodes within an electronic system that are interconnected via point-to-point link. The negotiation may ensure that there are no pending transactions or transactions that may occur within an upcoming period of time. Through this negotiation each component acknowledges and agrees to transition the link to the low power state.
