Abstract
An interrupt control apparatus includes: an interrupt request supply unit that supplies interrupt request information; a processing unit that performs interrupt processing based on the interrupt request information supplied by the interrupt request supply unit; and a time measuring unit that is used to measure an elapse of a predefined time period from a time point when the interrupt request supply unit starts to supply the interrupt request information, wherein: even if new interrupt cause information is stored during the time when the time measuring unit is measuring the elapse of the predefined time period, the interrupt request supply unit does not supply interrupt request information based on the new interrupt cause information to the processing unit; and after the elapsed time measured by the time measuring unit reaches the predefined time period, the interrupt request supply unit supplies the interrupt request information to the processing unit.
