PCT No. PCT/JP84/00535 Sec. 371 Date Jun. 25, 1985 Sec. 102(e) Date Jun. 25, 1985 PCT Filed Nov. 8, 1984 PCT Pub. No. WO85/02279 PCT Pub. Date May 23, 1985.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. |
