ABSTRACT:
In correspondence with an address of a branch instruction, a branch target address Apb, a valid bit V as branch history information, and delay slot information POS on the last position of delay slot instructions are stored in a branch target buffer241. A branch prediction circuit23outputs hit information H/M as to whether or not an input address Ao is coincident with the branch instruction address, the valid bit which is also a branch prediction bit, the information POS, and the branch target address Apb. When a prediction error signal ERR is inactive, the address selection circuit22selectively outputs the output of an incrementer21and the branch target address Apb, based on the hit information H/M, the delay slot information POS, and the valid bit V.
