Abstract
Multi-core platforms are emerging trends in the design of Systems-on-Chip (SoCs). Interconnect fabrics for these multi-core SoCs play a crucial role in achieving the target performance. The Network-on-Chip (NoC) paradigm has been proposed as a promising solution for designing the interconnect fabric of multi-core SoCs. But the performance requirements of NoC infrastructures in future technology nodes cannot be met by relying only on material innovation with traditional scaling. The continuing demand for low power and high speed interconnects with technology scaling necessitates looking beyond the conventional planar metal/dielectric-based interconnect infrastructures. Among different possible alternatives, the on-chip wireless communication network is envisioned as a revolutionary methodology, capable of bringing significant performance gains for multi-core SoCs. Millimeter-wave Wireless NoCs (mWNoCs) can be designed by using miniaturized on-chip antennas as an enabling technology. On-chip CMOS compatible millimeter-wave wireless links provide high bandwidth and low power communication channels over long distances. Hence they can be used to create short cuts between distant cores on the chip to provide fast and efficient traffic freeways. From standard network topologies used in traditional NoCs we move towards nature inspired ones like the Small-World graph. Such topologies inherently have low average inter-core distances and scale very well with increase in size. In this work, design methodologies and technology requirements for scalable mWNoC architectures are presented and their performance is evaluated. It is demonstrated that mWNoCs outperform their wired counterparts in terms of network throughput and latency, and that energy dissipation improves by orders of magnitude under various experimental and real-life scenarios.
