摘要： A processor may include a core and an uncore area. The power consumed by the core area may be controlled by controlling the Cdyn of the processor such that the Cdyn is within an allowable Cdyn value irrespective of the application being processed by the core area. The power management technique includes measuring digital activity factor (DAF), monitoring architectural and data activity levels, and controlling power consumption by throttling the instructions based on the activity levels. As a result of throttling the instructions, throttling may be implemented in 3rd droop and thermal design point (TDP). Also, the idle power consumed by the uncore area while the core area is in deep power saving states may be reduced by varying the reference voltage VR and the VP provided to the uncore area. As a result, the idle power consumed by the uncore area may be reduced.
