Abstract:
An interruption processing circuit for receiving and storing an event signal outputted at the occurrence of an event in a peripheral device and for outputting that event signal to a data processor monitoring conditions of said peripheral device comprising:a first storage device which, when said event signal is inputted from said peripheral device thereto, receives the event signal and stores it until a processing start timing signal outputted from said data processor is inputted thereto; and a second storage device where upon the input of said processing start timing signal thereto, the signal stored in said first storage device is transferred to the second storage device, and said second storage device stores the transferred event signal until a timing defined by an interruption information readout signal from said data processor, wherein said second storage device outputs the stored signal to said data processor at the timing defined by the interruption information readout signal, the timing being later than that defined by said processing start timing signal.
