Abstract
An input/output (I/O) system and method for coupling a host computer to a plurality of peripheral devices in which data destined for peripheral devices is transferred to an output data buffer whose locations are paired with output channel addresses stored in an output device table. A microcomputer performs any processing required on data stored in the output data buffer by reading the address and a function code in the output device table then distributes processed data to an output device block whose locations are addresses of output channels. An input data buffer and input device table similarly arranged, collects and processes input data continuously, which input data buffer can be transferred to the host computer, on command, in a high speed burst.
