    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 voltage regulator is described which uses external resistors to set a load line and offset. During initial operation and also during normal operation the load line and offset are reset by placing, for instance, the microprocessor in a high active state, low active state and in a sleep mode. By dynamically changing the load line and offset voltage, minimum current is drawn thus extending battery life.

    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： 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 indicate 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 method is disclosed including generating a digital control signal having a duty cycle which varies randomly or pseudo-randomly between a number of cycles, and is substantially fixed when averaged over the cycles. A target signal such as a digital clock signal may be passed selectively, in accordance with the control signal. A particular application of the method is power management in computers and other electronic systems that feature high performance processor and memory configurations that involve synchronous accesses of the memory by the processor.
