Abstract: The invention relates to a unique input/output channel used in a data processing system. The channel couples a plurality of external devices and their control units to a central processing unit. The configuration of the channel is such that it allows each of the control units direct control over many of the central processing unit functions during an input/output cycle. It allows each of the control units to share the system''s main storage and central processing unit during these cycles. The design further allows for local store registers located in the central processing unit to be used as address registers for the external devices.
