ABSTRACT:
A branch predicting apparatus includes a prediction information buffer for supplying prediction information related to branch prediction of a branch instruction, at a same timing as fetching of an instruction fetched before the branch instruction, and a branch predicting mechanism for reading, if necessary, information required for branch prediction from a register file storing a result of operation of an instruction pipeline in accordance with the prediction information supplied from the prediction information buffer, performing branch prediction of the branch instruction by, at the latest, completion of the fetch cycle of the branch instruction, and for outputting a branch prediction signal.
