摘要：A method of configuring a prescaling circuit in a performance counter circuit for
a computer processing system can include receiving a first number of signaled events at aprescaling circuit configured to generate event counts for a performance counter circuit.The method can include generating event counts at a current event-count rate for thefirst number of signaled events and determining a detected event-count rate for thesignaled events based on a rate at which the first number of signaled events are receivedat the prescaling circuit. The method can include determining that the detected event-count rate is greater than the current event-count rate. The method can includeincreasing the current event-count rate in response to determining that the detectedevent-count rate is greater than the current event-count rate.
