A branch operation is processed using a branch predict instruction (300) and an associated branch instruction. The branch predict instruction (300) indicates a predicted direction (310), a target address (320), and an instruction address (330) for the associated branch instruction. When the branch predict instruction (300) is detected, the target address (330) is stored at an entry indicated by the associated branch instruction address and a prefetch request is triggered to the target address (330). The branch predict instruction (300) may also include hint information (340) for managing the storage and use of the branch prediction information.
