ABSTRACT:
In a branch guess type central processing unit of the invention, for executing a branch instruction, a presignalling instruction for designating a branch address is prefetched by an address/prefetch control circuit before the branch instruction is read out from a macroinstruction memory. This presignalling instruction is decoded. The branch address is stored in advance in an A register, a B register, and a C register. A plurality of instructions stored at the locations represented by these addresses are stored in a first instruction register, a second instruction register and a stack before executing the branch instruction. When the branch instructions are executed, the control can be transferred to jumped locations without causing any hazard in the pipeline.
