A repeater, upon receiving an interrupt notification (151) from an I/O device, transmits a cause-of-interrupt read-out request (159 (1)) to the I/O device on the basis of an address information storage table (1041) without waiting for a response from a CPU, and transmits the received interrupt notification (151) to the CPU. When a cause-of-interrupt (160 (1)) is received, the repeater transmits an intra-I/O-device data read-out request (159 (2)) to the I/O device on the basis of an intra-I/O-device Ohdata read-out address storage table (1081) without waiting for a response from the CPU. |
