An arithmetic processor includes a first pipeline unit configured to execute a first instruction that is input; a second pipeline unit configured to execute a second instruction that is input; a registration unit into which an aborted instruction is registered, the aborted instruction being the first instruction when the first pipeline unit is unable to complete the first instruction or the second instruction when the second pipeline unit is unable to complete the second instruction; a determination unit configured to make a determination as to which one of the first pipeline unit and the second pipeline unit is operating under a lower load; and an input unit configured to input, in the first pipeline unit or the second pipeline unit that is determined as operating under the lower load by the determination unit, the aborted instruction that is registered in the registration unit.
