摘要： Methods are described allowing a vector signaling code to encode multi-level data without the significant alphabet size increase known to cause symbol dynamic range compression and thus increased noise susceptibility. By intentionally restricting the number of codewords used, good pin efficiency may be maintained along with improved system signal-to-noise ratio.

摘要： Vector signaling codes providing guaranteed numbers of transitions per unit transmission interval are described, along with methods and systems for their generation and use. The described architecture may include multiple communications sub-systems, each having its own communications wire group or sub-channel, clock-embedded signaling code, pre- and post-processing stages to guarantee the desired code transition density, and global encoding and decoding stages to first distribute data elements among the sub-systems, and then to reconstitute the received data from its received sub-system elements.

摘要： An efficient communications apparatus is described for a vector signaling code to transport data and optionally a clocking signal between integrated circuit devices. Methods of designing such apparatus and their associated codes based on a new metric herein called the “ISI Ratio” are described which permit higher communications speed, lower system power consumption, and reduced implementation complexity.
