• BR_MISPRED_DETAIL.ALL.WRONG_TARGET
Number of branch mispredictions that resulted from a mismatch of the predicted and actual
values of the branch target, independent of predictor.
• Total Predictions
Total number of branch predictions.
• Percent Correct Predictions
Percentage of branch predictions that predicted correctly.
• Percent Wrong Paths
Percentage of branch predictions that mispredicted the branch predicate.
• Percent Wrong Branch Targets
Percentage of branch predictions that mispredicted the branch target.

• BE_FLUSH_BUBBLE.ALL
Number of full-pipe bubbles in the main pipe due to either an exception/interruption or a
branch misprediction flush.
• BR_MISPRED_DETAIL.IPREL.CORRECT_PRED
Number of correctly predicted (outcome and target) IP-relative branches retired.
• BR_MISPRED_DETAIL.IPREL.WRONG_PATH
Number of IP-relative branches mispredicted due to wrong branch direction.
• BR_MISPRED_DETAIL.IPREL.WRONG_TARGET
Number of IP-relative branches mispredicted due to wrong target for taken branch.
• BR_MISPRED_DETAIL.NRETIND.CORRECT_PRED
Number of correctly predicted (outcome and target) non-return indirect branches retired.
• BR_MISPRED_DETAIL.NRETIND.WRONG_PATH
Number of non-return indirect branches mispredicted due to wrong branch direction.
• BR_MISPRED_DETAIL.NRETIND.WRONG_TARGET
Number of non-return indirect branches mispredicted due to wrong target for taken branch.
• BR_MISPRED_DETAIL.RETURN.CORRECT_PRED
Number of correctly predicted (outcome and target) return branches retired.
• BR_MISPRED_DETAIL.RETURN.WRONG_PATH
Number of return branches mispredicted due to wrong branch direction.
• BR_MISPRED_DETAIL.RETURN.WRONG_TARGET
Number of return branches mispredicted due to wrong target for taken branch.
• CPU_OP_CYCLES.ALL
Number of variable clock cycles. (When charge rationing is on, the period of the cycle could
change.) It does not count cycles when the CPU is in low power mode.
• Total Predictions
Total number of branch predictions.
• Percent Correct Predictions
Percentage of branch predictions that predicted correctly.
