description A circuit and method for using hardware to calculate a first derivative of the number of performance events that occur in a microprocessor during a predetermined period of time. This first derivative indicates a frequency of such performance events, which can be used as either a predictor of future problems or needs, or may be used to invoke a corrective action.
