Mitch Hayenga: "SCARAB: A Single Cycle Adaptive Routing and Bufferless Network"

Recent research has proposed bufferless routers as a means to alleviate the power and area constraints for on-chip networks. To date all designs exhibit poor operational frequency, throughput, or latency. In this paper, we propose an efficient bufferless router which lowers average packet latency by 17.6% and dynamic energy by 18.3% over existing bufferless on-chip network designs.

Dana Vantrease: "Light Speed Arbitration and Flow Control for Nanophotonic Interconnects"

By providing high bandwidth chip-wide communication at low latency and low power, on-chip optics can improve many-core performance dramatically. Optical channels that connect many nodes and allow for single cycle cache-line transmissions will require fast, high bandwidth arbitration. We exploit CMOS nanophotonic devices to create arbiters that meet the demands of on-chip optical interconnects. We accomplish this by exploiting a unique property of optical devices that allows arbitration to scale with latency bounded by the time of flight of light through a silicon waveguide that passes all requesters.
