INPUT/OUTPUT INTERRUPT SYSTEM ABSTRACT OF THE DISCLOSURE A data processing system having a channel processing device provided with an input/output device which requires input/output interrupt, the channel processing device responding to a request for input/output inter- rupt, propagating the request for input/output interrupt to a central processing unit, and reporting the state of the input/output device to the central processing unit. The channel processing device comprises an interrupt detecting means which detects the request for input/ output interrupt sent from the input/output device to the channel processing device, a status information detecting means which detects whether the status information sent from the input/output device to the channel processing unit together with the request for input output interrupt is a predetermined specified value, and a counting means which counts a predetermined constant time when the status information detecting means detects the predetermined specific value so that the request for input/output interrupt is sent to the central processing unit after the counting means counts the constant time.
