Abstract
Disclosed is a channel control system for controlling data transfers between a main storage and input/output devices. A plurality of channels are controlled by a common controller. The controller divides the processing for data transfer requests into a plurality of processing stages to allow the corresponding number of the channels to be controlled simultaneously by executing the processing for different channels separately at the divided individual processing stages.
