...d actually either be * Decoder cycles: NumDecoderSlots(SU) => SU->NumMicroOps and DecoderCapacity => IssueWidth  (1) or * Execution cycles: NumExecutedUOps(SU) => SU->NumMicroOps and ApproxMaxExecutedUOpsPerCycle => IssueWidth (2) They would at least in this context be somewhat equievalent in driving CurrCycle forward. Please, let me know about (1) or (2)  :-) thanks /Jonas
