Data exchange between modules of digital system - using microprogrammable controller, common bus, and comparator transfer circuit

摘要

A device for carrying out data exchange between digital circuits is designed for general applicability, thus enabling use, of the functional capabilities of new types of digital device. The data exchange is controlled by a microprogrammable controller with suitable outputs. Digital modules with isolatable inputs and outputs enable activation of individual controller microprogram segments for control of data exchange. A common bus operating in time multiplex is used for all digital module inputs and outputs and for operational as well as structure defining data. Data transfer between module inputs and outputs takes place via a comparator.
