  • Propulsion control system cental processing unit board
    Patent number: 5488733
    Abstract: For use in a propulsion control system, a microprocessor based central processing unit board includes both Multibus I and Multibus II interfaces. Multibus I master interface and Multibus slave interface controllers are designed for high data throughput by using programmed logic design (PLD) technology. In addition, the need for latching of data transceivers used in conventional Multibus I designs is eliminated. The Multibus II interface is removable.
    Type: Grant

  • Communications controller central processing unit board
    Patent number: 5475818
    Abstract: A microprocessor based data communications controller board includes at least one microprocessor and is for controlling communications over a plurality of busses having different electrical specifications and using different communications procedures. The board includes a first interface for interfacing the microprocessor based data communications controller board with a first communications bus providing a multidrop serial master-slave synchronous data link controlled communications system. The board also includes a second interface for interfacing the microprocessor based data communications controller board with at least one second communications bus providing a Manchester encoded multidrop master-slave high-level data link controlled communications system. And the board also includes a third interface for interfacing the microprocessor based data communications controller board with a third communications bus providing a parallel processor-to-processor message passing communications system.
