An encoding process for bus data utilizes data from multiple data line groups on a multi-byte
wide bus where each group has an associated DBI line. The process leverages the …

Methods of operating a serial data bus divide series of data bits into sequences of one or
more bits and encode the sequences as N-level symbols, which are then transmitted at …
