Claim Text:
1. An interrupt signal accepting apparatus, managing operations of at least two operating systems (OSs) and accepting interrupt signals from a plurality of devices, wherein an interrupt number notified by an interrupt signal and an OS caused to process the interrupt signal as a specified OS are specified to each of the plurality of devices, the interrupt signal accepting apparatus comprising: processing circuitry configured to performs as an OS unique value information storing section that stores OS unique value information to relate each of at least two number sharing devices which share the same interrupt number, to the specified OS of each number sharing device, a unique value which is unique to each number sharing device, and a shared interrupt number which is shared by the at least two number sharing devices; the processing circuitry further configured to perform as a conversion value information storing section that stores conversion value information to specify a unique value selected from among at least two unique values related to the shared interrupt number in the OS unique value information as a conversion value of the shared interrupt number, for each shared interrupt number; and the processing circuitry further configured to perform as an interrupt signal control section that: changes the conversion value information, and causes an OS other than the running OS to start as a new running OS and the running OS to stop, the OS other than the running OS being related in the OS unique value information to the unique value which is the same as the conversion value obtained by converting the shared interrupt number in accordance with the changed conversion value information.
