Abstract:
1. A digital visual information handling system comprising: M×N digital data comprising M sets of digital signals, each of the M sets comprising N digital signals representing an n-bit code; at least one transition minimized differential signaling encoder coupled to a receive the M×N digital data on M sets of first parallel lines and coupled to transmit the encoded M×N digital data on a plurality of second parallel lines; a pseudo-random binary sequence generator circuit to generate test data on a plurality of third parallel lines; M number of multiplexers coupled to the plurality of second parallel lines, the plurality of third parallel lines, and a plurality of fourth parallel lines, wherein each multiplexer is associated with one of the M sets of the encoded M×N digital data and wherein each multiplexer selectively passes the encoded digital data and the test data to the plurality of fourth parallel lines according to a specified signal; a serializer coupled to the M number of multiplexers to serialize the encoded M×N digital data and the test data; and at least one buffer circuit coupled to the serializer to convert the serial digital data to M sets of differential signals.
