Abstract

PURPOSE: To prevent the deterioration of CPU's processing ability due to a continuously arising asynchronizing interruption by providing a means storing the time when an interruption from an I/O device is reported to the CPU at every interruption in an I/O controller.
CONSTITUTION: The I/O controller 2 is connected to the central processing unit CPU 1, and one or more I/O devices 3 are connected under the control of the controller 2. In terms of the controller 2, a memory device 22 stores the time when the asynchronizing interruption occurs and its phenomenon, the memory device 23 stores at every interruption the reporting time when said asynchronizing interruption is reported to the CPU1, a memory device 24 stores at every interruption the interval of the asynchronizing interruption arising time when the device 3 is in normal operation, and a memory device 25 stores the phenomenon of the previously arising asynchronizing interruption. When an interruption processing unit 26 accepts the asynchronizing interruption, it decides whether it reports said interruption to the CPU 1 or not.
