This performance group returns the ratios of used and unused cycles regarding
|
||
|
|
the issue stage in the pipeline. Used cycles are all cycles where uOPs are
|
||
|
|
issued while unused cycles refer to pipeline stalls. Moreover, the group
|
||
|
|
calculates the average stall duration in cycles.
