Abstract
A Data Exchange Subsystem comprising a data bus for transferring data signals, a load for normally maintaining a logical one signal on the data bus, a number of data receivers operatively connected to the data bus for sensing the logic state of the data signal, and a number of data transmitters operatively connected to the data bus for driving their respective data onto the bus. The data transmitter utilize open collector output buffers to force the data signal to a logical zero in response to corresponding data provided to the respective data transmitters, thereby collectively forming a 'wired-and' structure, providing the Data Exchange Subsystem with an inherent data conflict resolving capability that may be utilized in data-dependent operations such as data masking.
