Abstract: A multiple channel input/output channel system for information processing systems, including one or more control modules each having a unit for translating program elements, modular data service apparatus controlled by I/O data transfer descriptors provided by the translational unit, and a memory interface unit for controlling the transfer of information between the translator and data service units and a data processing system memory. The translator unit asynchronously obtains I/O program words or elements from the processing system and combines designated portions of them to form data transfer descriptors for input/output tasks to be done. The data service apparatus interfaces with a plurality of peripheral control units which are coupled for controlling peripheral input/output devices either directly or via multiple-path peripheral exchange units.
