ABSTRACT:
A Nyquist sampling frequency is determined for performance counter events to be measured. Based on the Nyquist sampling frequencies, a schedule for measuring the performance counter events is determined. The performance counter event measurements are then conducted in accordance with the schedule, whereby the measurements yield a set of sample data for each performance counter event. A signal reconstruction algorithm is applied to the set of sample data for each performance counter event to reconstruct an essentially complete signal for each performance counter event. The essentially complete signal for each performance counter event is then used to improve either a design or a utilization of either a microprocessor or an application to be executed on the microprocessor.
