Abstract
In a chip-to-chip communication system and apparatus, a set of physical signals to be conveyed over a communication bus is provided, and mapped to a codeword of a vector signaling code using the physical signals and a state information, wherein a codeword is representable as a vector of plurality of real-valued components, and wherein a vector signaling code is a set of codewords in which the components sum to zero and for which there is at least one component and at least three codewords having different values in that component; and wherein the state information is a plurality of information present in continuous or discrete form which may have been obtained from previous codewords transmitted over the communication bus.
