Abstract
A 2-bit communication channel is made to transmit complex data patterns by partitioning a digital string into 3-bit binary patterns which are encoded into 4 bits binary pattern and transmitted over the 2-bit communication channel in pairs using adjacent clock cycles on the 2-bit channel. Pre-defined ones of the 4-bit encoded data structures are used for framing on the channel and cannot be used to transmit data.
