Digital system for data transfer using universal input-output microprocessor

摘要

A digital system which a main host computer is connected for communication with a plurality of base modules. Each base module supports a plurality of peripheral-controllers which include an application dependent logic module for handling the specific needs in data transfers to/from a particular type of peripheral device. Each peripheral-controller comprises a universal standardized microprocessor which works in conjunction with said application dependent logic module. Means are provided in the microprocessor and the microprocessor system operating with said application dependent logic module to control and handle data transfer functions between said main host computer system and remote peripheral devices.
