Abstract

PURPOSE: To reduce the cost of a unit by making a sub-channel register small and by reducing the capacity of a sub-channel, by making an interrupt by a one-directional chain.
CONSTITUTION: Sub-channel register SBCR in sub-channel memory SBCM3 is provided with area NIQR stored with interruption pending information and registration information and addresses of IOs causing interruptions. Further, registers FIQR6 and LIQR7 are provided which are stored with addresses of IOs positioned at the head and tail of the queue. When an instruction for processing earlier an interruption in process of interruption queuing is made to an IO registered in the queue, the SBCR equivalent to the IO is read out to the work register to check interruption pending information, so that when an interruption to be processed is held, the information will be reset. Further, when the TIO instruction resides at the head of the IO, the process of NIQR is performed from the IO of the stored address.
