Multi-wire single-ended push-pull link with data symbol transition based clocking

摘要

System, methods and apparatus are described that facilitate transmission of data over a multi-wire data communications link, particularly between two devices within an electronic apparatus. A sequence of data bits is converted into M transition numbers, which are then converted into a sequence of symbols. The sequence of symbols is transmitted received over N wires. A clock signal may be effectively embedded in the transmission of the sequence of symbols. Each of the sequence of symbols may be selected based on a corresponding one of the M transition numbers and a value of a preceding one of the sequence of symbols.

1. A method for multi-wire signaling, comprising:
converting a sequence of data bits into a plurality of M transition numbers, where M is an integer greater than 1; converting the M transition numbers into a sequence of symbols, wherein each of the sequence of symbols is selected based on a corresponding one of the M transition numbers and a value of a preceding one of the sequence of symbols; and transmitting the sequence of symbols over N wires using N single-ended drivers, where N is an integer greater than 1, wherein a clock signal is effectively embedded in the sequence of symbols.
