PROBLEM TO BE SOLVED: To provide a technology capable of processing a plurality of interruption factors sharing one interruption request by different processors. SOLUTION: An interruption controller 5 outputs an interruption request IRQ1 when the interruption request IRQ1 shared by a plurality of interruption factors is notified. The interruption request IRQ1 to be output by the interruption controller 5 is accepted by either one of the processors 1 and 2. The processor which has received the interruption request IRQ1 decides whether or not the interruption factor to be processed by itself is generated, and when deciding that the interruption factor is generated, the processor executes the interruption processing, and when the interruption factor is not generated, the processor notifies the other processor which processes the other interruption factors among the plurality of interruption factors sharing the interruption factor IRQ1 of the generation of the interruption factor IRQ1.
