Performance prediction of on-chip high-throughput global signaling

On-chip global signaling whose performance improves with technology advance is eagerly demanded. This work focuses on wave pipelining on on-chip transmission lines, which is one of probable solutions, and predicts the trend of signaling performance in the future. Experiments reveal that transmission capacity per channel will improve till at least 35nm technology in 10mm-long or below signaling. We also demonstrate that current-mode differential signaling is robust against power supply noise, but power delivery with nonzero impedance degrades the performance.
