    摘要: According to the present invention, an instruction address register unit I for reading instructions and an instruction address register unit II for indicating the address of the instruction being executed in the pipeline are provided independently. The address of a branching instruction is held in the instruction address register unit II until said instruction passes through the pipeline, the content of instruction address register unit I is updated when branching of the branching instruction is determined, and thereby delay in reading an instruction after 8 bytes at the branching address can be reduced.
