ABSTRACT:
An information processing apparatus having a buffer register for pre-fetching a plurality of instructions and executing one instruction after another by reading them from the buffer registers, is provided with a first instruction decode start determination unit for register type instructions and a second instruction decode start determination unit for non-register type instructions, provided separately from the first unit, whereby 0.5 cycle after a register type instruction starts being decoded, or 1 cycle after a non-register type instruction starts being decoded, the next instruction starts to be decoded. By decoding a register type instruction at high speed, it becomes possible to execute a branch instruction at high speed.
