Abstract
In an embodiment, a digital power estimator (DPE) may be provided that may monitor the processors to estimate the amount of power being consumed. If the estimate exceeds a power threshold, the DPE may throttle one or more of the processors. Additionally, throttling events may be monitored to determine if a change in the operating point is desired. In one embodiment, the DPE throttling events may be counted, and if the counts exceed a count threshold, a change in the operating point to a reduced operation point may be requested. Additionally, if the DPE estimate is below the power threshold (or a second power threshold), a second count of events may be maintained. If the second count exceeds a threshold and the operating point is the reduced operating point, a return to the original operating point may be requested.
