Abstract

An electronic computer includes a processor that executes a thread and an interrupt handler, and monitors load of the processor; and an interrupt controller that is configured to determine a notification timing for an interrupt request to call the interrupt handler, the notification timing being determined based on the load and an effect of execution of the interrupt handler on user performance of the thread under execution by the processor; and notify the processor of the interrupt request, based on the notification timing. When the load is higher than a threshold, the interrupt controller sets the notification timing for an interrupt request that does not affect the user performance, to be later than the notification timing for an interrupt request that affects the user performance. Based on notification of the interrupt request, the processor calls and executes the interrupt handler that corresponds to the interrupt request.
