<p>In a method embodiment, there are steps (160) to operate a microprocessor having at least one counter located on the microprocessor. The method operates functional circuitry on the microprocessor over a plurality of clock cycles. This operation causes an on-chip activity to occur at least once during the plurality of clock cycles. The method also advances a count in the at least one counter in response to each incidence of the on-chip activity. After this advancement of the count, the method predicts (164) the busyness of the microprocessor in response to the count in the counter. Finally, the method selectively adjusts power consumption (168) of the microprocessor in response to a comparison of the predicted busyness with a threshold. <IMAGE></p> |
