Abstract
An input/output command processor provides a sophisticated communication link between a central processor and peripheral digital apparatus. The command processor receives commands from the central processor, interprets them and transmits them to the peripheral digital apparatus. The command processor is comprised of a store/fetch circuit for directly accessing the memory of the central processor; a fetch and buffer circuit for causing a fetch and for temporarily storing the results of the fetch (commands) in a buffer register file; an interpret controller for interpreting the commands and routing them to the cognizant peripheral apparatus, according to their function.
