ABSTRACT:
A programmable switch of three or more ports, each port having data lines separate from lines sharing control and addressing. The programmable switch includes internal logic control and electronic modules that accept and deserialize the control and address signals. The logic control directs the data in signals to one or more of the output data lines. Since the data and control and addressing lines are separate, the control may act concurrently with the data to direct the data properly. The sending unit must synchronize such operations to ensure data coherency and proper timing. The data signal path from any input to any or all outputs is designed to have, typically, only a single logic gate or on transistor switch delay.
