On-chip performance counters are gaining popularity as an analysis and validation tool. Most contemporary processors have between two and six physical counters that can monitor an equal number of unique events simultaneously at fixed sampling periods. Through multiplexing and estimation, an even greater number of unique events can be monitored in a single program execution. When a program is sampled in multiplexed mode using round-robin scheduling of a specified event set, the number of events… CONTINUE READING
