Higher power has become one of primary obstacles for improving the performance of processors. To manage the power of processor dynamically, it is necessary to obtain the power timely and accurately. Power estimation using performance events is a better way in terms of timeliness and accuracy. We analyzed the correlation between performance events and powers of microprocessors. Only one performance event was selected for the power estimation of one functional unit based on the correlation analysis. The power of each functional unit was estimated based on simple regression analysis. In addition, the impact of ambient temperature on the accuracy for power estimation was presented. It can be seen from the experimental results that (1) the power of each functional unit has close linear correlation with a performance event and can be estimated accurately; (2) the ambient temperature has the negative impacts on the accuracy for power estimation.
