ABSTRACT:
A performance monitor includes at least one Monitor Mode Control Register (MMCR) and plural Performance Control Monitors (PMCs). Each PMC is controlled by the MMCR to pair or group the PMCs so that the overflow from one PMC can be directed to its pair/group. By coupling the PMCs so that overflow from one can be directed to another, the effective size of the counters can be increased.
