Abstract

This parallel data transmission scheme allows the high speed transmission of data between parallel channels and control units over long distances by solving the bit-skewing problem. The data is placed into the transmitter in byte form. A self- clocking transmission on each bus-line follows. At the receiving end, the data is decoded, buffered into shift registers, and delivered at the destination in byte form again. The length of the shift registers depends on the maximum transmission bit-skew. In earlier implementations, channel-control unit communications were carried out over byte-wide unidirectional buses with acknowledgment signals exchanged at every byte transfer.
