A Scalable Hierarchical Ring Based Wireless Network-on-Chip

Abstract

Network-on-Chip (NoC) based systems are becoming more acceptable nowadays compared to System-on-Chips (SoC) for nanoscale system development due to increasing scaling. The weakness of wired communication leads to insertion of wireless links in NoC Systems to mitigate the multihop problem. Present work provides significant improvements of NoC and Wireless NoC (WNoCs) systems contributing salient techniques related to necessary hardware and communication protocols. This work also explores experiments on NoC and WNoC systems. Proposed WNoC design offers 33.19% - 47.49% improvements in latency with 15.73% - 23.06% gain in energy consumption and latency improvements of 52.60% - 56.55% with 22.65% - 29.16% savings in consumed energy over mesh based wired traditional NoC and another state-of-the-art WNoC respectively.
