Abstract
When an interrupt request to a control unit occurs, the control unit polls a plurality of interrupt request terminal interfaces to locate which of the interrupt request terminal interfaces has generated the interrupt request. The control unit polls the plurality of interrupt request terminal interfaces in groups of several interrupt terminal interfaces to locate a group to which the interrupt request terminal interface has generated the interrupt request belongs, and polls only the respective interrupt requests terminal interfaces belonging to the located group to thereby locate the generated source of the interrupt request. Each interrupt request terminal interface generates an interrupt request as vector data indicative of contents directly corresponding to each interrupt condition.
