CONDITIONAL NON-BRANCH INSTRUCTION PREDICTION |
摘要 |
A microprocessor processes conditional non-branch instructions that specify a condition and instruct the microprocessor to perform an operation if the condition is satisfied and otherwise to not perform the operation. A predictor provides a prediction about a conditional non-branch instruction. An instruction translator translates the conditional non-branch instruction into a no-operation microinstruction when the prediction predicts the condition will not be satisfied, and into a set of one or more microinstructions to unconditionally perform the operation when the prediction predicts the condition will be satisfied. An execution pipeline executes the no-operation microinstruction or the set of microinstructions. The predictor translates into a second set of one or more microinstructions to conditionally perform the operation when the prediction does not make a prediction. In the case of a misprediction, the translator re-translates the conditional non-branch instruction into the second set of microinstructions.
