  • Data processing system and method for implementing a switch protocol in a communication system
    Patent number: 5949982
    Abstract: A cross-bar switch is implemented in a multiprocessor system which allows for bidirectional communication between a device and the cross-bar switch such that information may be transferred simultaneously between both. The cross-bar switch is not informed of the integrated circuit device's actions before a communication link is established. Rather, the bidirectional transmitter utilized herein allows the transmission of control information to the cross-bar switch while the cross-bar switch communicates to the integrated circuit device over the same transmission lines. Such bidirectional communication allows the designer of a multiprocessor communication system to minimize control lines and transmit both data and control signals over the same communication bus.
