ABSTRACT:
An information processing apparatus is of such a type that, between a system including a main board and a corresponding expansion board mounted in a corresponding expansion slot, the apparatus makes a given interruption to the expansion board, via a system bus, for each slot. The main board comprises a main CPU for gaining access to an interruption input/output port corresponding to one associated expansion board and a system bus interface for selecting one expansion board to which an interruption is to be made. The expansion board comprises a system bus interface for receiving an expansion slot select signal from the system bus interface and generating a control signal, an interruption input/output address decoder for decoding an input/output address entered via the system bus and for generating an interruption signal, and a sub CPU for receiving the interruption signal and for performing interruption processing.
