A relaying device, when having received an interrupt notification 151 from an I/O device, transmits an interrupt factor read request 159(1) for an interrupt factor to the I/O device, based on an address information memory table 1041, without waiting for a response from a CPU, and transmits the interrupt notification 151 received, to the CPU. When having received an interrupt factor 160(1), the relaying device transmits an intra-I/0-device data read request 159(2) to the I/O device, based on an intra-I/O-device data read address storing table 1081, without waiting for a response from the CPU. |
