PROBLEM TO BE SOLVED: To provide an interruption controller in which a multiprocessor can process an interruption more efficiently than a single processor even when a demanded interruption is one, and can ever enhance the processing efficiency of the multiprocessor. SOLUTION: An interruption controller 1 which controls an external interruption processing of a multiprocessor 4 with two or more unit processors, is configured by an interruption detection section 203 which receives an interrupt request; an interruption controller 204 which divides the interrupt request received by the interruption detection section 203 into two or more interrupt vectors, and makes allocation of the divided interrupt processes to a plurality of unit processors which the multiprocessor 4 has; an interruption association table 202; an interruption destination processor selection control section 206; and a processor state management section 207.
