ABSTRACT:
An information processing apparatus performing pipeline control includes a first fetch cue fetching a non-branch location instruction, a second fetch cue fetching a branch location instruction, a fetch circuit which carries out arithmetic of a fetch address, fetch it to the first fetch cue or the second fetch cue, and outputs a first fetch cue or a second fetch cue instruction to a decode circuit, a decode circuit which receives and decode an instruction code fetched to the first fetch cue or the second fetch cue, and an execution circuit performing execution of an instruction based on a decoding result, wherein the above-mentioned fetch circuit includes a selective circuit which selects which instruction of the first fetch cue or the second fetch cue to send to the decode circuit based on the execution result of a comparison instruction.
