Abstract
PURPOSE: To simplify multiple control over several channel programs by making it possible to execute a channel program while the execution of another program is in process, and also by eliminating the overhead of an interruption at the time of data transfer between data processor.
CONSTITUTION: Between data processors 1 and 2 consisting of CPUs 22 and 21, channel units 3 and 4, and main memory unit 6, inter-channel coupler 5 is arranged and in accordance with input and output commands sent from units 3 and 4, data transfer is carried out. This coupler 5 is provided with circuit 8 on the side of channel coupler A of unit 1 and circuit 18 on the side of channel coupler B of unit 2 and when receiver circuit 9 of A-side circuit 8 receives an input-output command indicating the start of data transfer and a command corresponding to the command is not received from its party side, information is stored in temporary memory unit 13 connected to control circuit 12 to interrupt the execution of the command. When the corresponding command is received from the other processor in succession, the execution of the command is restarted by information stored in unit 13.
