Performance Evaluation and Design Trade-Offs of Wireless SWNoCs

To enhance the performance of conventional interconnect-based multicore chips, on-chip wireless interconnect has emerged as a radically different technology. However, this emerging interconnect paradigm imposes significant challenges pertaining to reliable integration and design. This chapter focuses on the performance evaluation of two types of wireless small-world NoC architectures. One uses carbon nanotube antennas, whereas the other uses with millimeter-wave antennas. Both are shown to outperform traditional wire-based NoCs by several orders of magnitude in power dissipation and latency. The wireless small-world NoC is also compared against a wireless hierarchical NoC for complete analysis.
