An information processing device includes an instruction fetch unit, an instruction buffer, an instruction executing unit, and an instruction fetch control unit. The instruction fetch unit supplies a fetch address to an instruction memory. The instruction buffer stores an instruction read out from the instruction memory. The instruction executing unit decodes and executes the instruction supplied from the instruction buffer. The instruction fetch control unit stops supply of the fetch address to the instruction memory by the instruction fetch unit when the fetch address corresponds to a first address or an address after the first address while the instruction executing unit executes loop processing. The loop processing is repeatedly executed for a predetermined number of times in accordance with decoding of the loop instruction by the instruction executing unit. The first address is an address after an address of an end instruction included in the loop processing. |
