A high-speed parallel interface for communicating data between integrated
circuits is disclosed. The interface is implemented by a transmitter and
receiver pair and a single-ended parallel interconnect bus coupling to
the transmitter and receiver pair. As opposed to transmitting small swing
signals over differential signal lines, the transmitter transmits data to
the receiver at full swing over the single-ended parallel interconnect
bus. The invention can be implemented with simple CMOS circuitry that
does not consume large die area. Accordingly, many link interfaces can be
implemented on a single chip to provide a large data bandwidth.
