TRANSCODING METHOD FOR MULTI-WIRE SIGNALING THAT EMBEDS CLOCK INFORMATION IN TRANSITION OF SIGNAL STATE

摘要

A method for performing multi-wire signaling encoding is provided in which a clock signal is encoded within symbol transitions. A sequence of data bits is converted into a plurality of m transition numbers. Each transition number is converted into a sequential number from a set of sequential numbers. The sequential number is converted into a raw symbol that can be transmitted over a plurality of differential drivers. The raw symbol is transmitted spread over a plurality of n wires, wherein the clock signal is effectively embedded in the transmission of raw symbols since the conversion from transition number into a sequential number guarantees that no two consecutive raw symbols are the same. The raw symbol is guaranteed to have a non-zero differential voltage across all pairs of the plurality of n wires.

1. A method for performing multi-wire signaling decoding, comprising: receiving a raw symbol spread over a plurality of n wires via a plurality of
differential receivers; converting the raw symbol into a sequential number from a set of sequential numbers; converting each sequential number to a transition number; converting a plurality of transition numbers into a sequence of data bits; and extracting a clock signal from the reception of raw symbols.
