Description
Summary:This paper presents an encoding variation on the Crosstalk-Harnessed Signaling (CHS) technique, aimed towards eliminating the common-mode eigenvector included in the Hadamard matrix for CHS encoding/decoding. This is accomplished by either removing the eigenvector or making it differential by concatenating matrices in a diagonal fashion, or by adding columns to the matrix; this results in a non-square matrix that delivers a larger number of signals to be routed in the interface. Simulation results show the signaling/routing overhead translates in a significantly higher performance for high-speed parallel interfaces with very high routing integration levels.
