MICROPROCESSOR WITH DIGITAL POWER THROTTLE |
摘要 |
The present invention provides a digital-based mechanism for adjusting the power consumption in an integrated digital circuit such as a processor. The processor includes one or more functional units and a digital throttle that monitors activity states of the processor's functional units to estimate the processor's power consumption. One embodiment of the digital throttle includes one or more gate units, a monitor circuit, and a throttle circuit. Each gate unit controls the delivery of power delivery to a functional unit of the processor and provides a signal that indicates the activity state of its associated functional unit. The monitor circuit determines an estimated power consumption level from the signals and compares the estimated power consumption with a threshold power level. The throttle circuit adjusts the instruction flow in the processor if the estimated power consumption level exceeds the threshold power level. |
