Abstract
A method for identifying bottlenecks within a processing system, the processing system including a plurality of performance monitor counters (PMCs) and at least one monitor mode control register (MMCR) to configure the operations of at least one of the PMCs, includes, for a predetermined sampling period, counting a number of cycles that a dispatch unit is stalled, counting a number of cycles that each of a plurality of execution units is stalled, counting a number of cycles that a load/store unit is stalled, and counting a number of cycles that a completion unit is stalled. The counting in the units is performed to identify the relative effect of stalls occurring within each unit during processing to produce an overview of relative effect of the stalling of each unit on the total system bottleneck conditions.
