Abstract

PURPOSE:To make high speed and efficient interruption possible, by providing a storage device to which a channel processing device and a central processing unit are freely accessable. CONSTITUTION:A channel processing device operated with an instruction of a central processing unit 2 stores status information to an area assigned at each channel processing device on a storage device 4 after the end of operation and gives an interruption request signal to the central processing unit. When the central processing unit 2 can process the interruption from the channel processing device, the status information of the channel processing device is moved from the area of the storage device 4 corresponding to the channel processing device to a fixed address of a main storage device 1, and allots an interruption reception signal to the corresponding channel processing device. The corresponding channel processing device cancels the interruption request signal.
