摘要： In accordance with an embodiment of the present invention, a triggering event is initiated to place a processor in a low power state. The processor may or may not flush a cache upon entering the low power state depending on a power status signal. The power status signal may indicated the relative priority of power reduction associated with placing the processor in the low power state without first flushing the cache versus an increase in soft error rate in the cache associated with reducing the voltage in the low power state.

摘要： A computer system having one or more components capable of being in either wake or sleep states includes a power manager and a voltage regulator. The power manager may generate a power state signal indicating the power state of the component, and this signal may be provided to the voltage regulator. The voltage regulator may supply power to the component. The target voltage level of the power may be dependent on both a current level of the power and the power state signal.

摘要： A method for a mechanism for processor power state aware distribution of lowest priority interrupts. The method of one embodiment comprises receiving first power state information from a first component and second power state information from a second component. First task priority information from the first component and second task priority from the second component are also received. An interrupt request from a first device for servicing is received. Power state and task priority information for the first and second components are evaluated to determine which component should service the interrupt request. Either the first component or the second component is selected to be a destination component to service the interrupt request based on the power state and task priority information. The interrupt request is communicated to the destination component.

摘要： A system and method for throttling a slave component of a computer system to reduce an overall temperature of the computing system upon receiving a first signal is disclosed. The first signal may be from a master component indicating that a temperature for the master component has exceeded its threshold temperature. The slave component or the master component may be a central processing unit, a graphics memory and controller hub, or a central processing unit memory controller hub. The slave component may send a second signal to indicate that a temperature for the slave component has exceeded its temperature. The master component would then initiate throttling of the master component to reduce the overall temperature of the computing system. The master component may be throttled to a degree less than the slave component. A first component may be designated the master component and the second component may be designated the slave component based on a selection policy. The selection policy may be received from a user through a graphical user interface. The selection policy may be based on an action being performed by the computing system.

摘要： A method and apparatus for operating an integrated in a reduced-power consumption state are described. The apparatus comprises power-reduction logic which, to place the integrated circuit in the reduced-power consumption state, gates a clock signal to both first and second sets of functional units within the integrated circuit. The first set of functional units is distinguished in that it is required to perform cache coherency operations within integrated circuit. The apparatus includes an input which is coupled to receive a signal indicating a memory access, to a memory resource accessible by the integrated circuit, by a further device external to the integrated circuit. In response to the assertion of this signal, the power-reduction logic propagates the clock signal to the first set of functional units, to enable this set of functional units to perform a cache coherency operation which may be necessitated by the memory access by the external device.
