Chord signaling techniques for noise cancellation in chiplet interconnect data interfaces
摘要
Abstract
Chiplet technology has garnered significant attention owing to its potential to enhance integrated chip yield,reduce research costs,and bolster efficiency.To facilitate the interconnection of distinct chips,high-speed data interfaces are imperative.With the aim of augmenting total bandwidth density,chiplet interconnections predominantly employ single-ended signals for data transmission,which are susceptible to common-mode noise,synchronous switching noise,and crosstalk noise.Chord signaling transforms single-ended signals into pseudo-differential signals through encoding and decoding transmitted data,enabling noise suppression and enhancement of signal trans-mission quality.Furthermore,as a modulation technique,chord signaling is extensively adopted due to its process independence,architec-tural flexibility,and strong process portability.This paper conducts a comprehensive review of prevalent chord signaling techniques,in-cluding analysis and summary of their performance.Finally,it offers a perspective on the chord signaling development.关键词
