•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

•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
