With the increasing number of cores in chip multiprocessors, the design of an efficient communication fabric is essential to satisfy the bandwidth and energy requirements of multi-core systems. Scalable Network-on-Chip (NoC) designs are quickly becoming the standard communication framework to replace bus-based networks. However, the conventional metallic interconnects for inter-core communication consume excess energy and lower throughput which are major bottlenecks in NoC architectures. On-chip wireless interconnects can alleviate the power and bandwidth problems of traditional metallic NoCs. In this paper, we propose an adaptable wireless Network-on-Chip architecture (A-WiNoC) that uses adaptable and energy efficient wireless transceivers to improve network power and throughput by adapting channels according to traffic patterns. Our adaptable algorithm uses link utilization statistics to re-allocate wireless channels and a token sharing scheme to fully utilize the wireless bandwidth efficiently. We compare our proposed A-WiNoC to both wireless/electrical topologies with results showing a throughput improvement of 65%, a speedup between 1.4-2.6X on real benchmarks, and an energy savings of 25-35 %. © 2013 IEEE.
