Achievable Performance Enhancements with mm-Wave Wireless Interconnects in NoC

Abstract

On-chip wireless links have been shown to overcome the performance limitations of wired interconnects in Networks-on-chip (NoCs). However actual performance gains obtained are largely dependent on efficient data transmission between on-chip antennas. An analysis of on-chip wireless channel shows that propagation is highly affected by different components of the chip. In this work, we include the effects of chip environment on wireless propagation to obtain a more realistic performance evaluation of Wireless NoC (WiNoC). Using these, we derive the latency and energy characteristics of WiNoC and quantify the achievable performance. Results presented show wireless received signal with on-chip effects considered and compare them with that of a wired link.
