The continuing progress and integration levels in silicon technologies make complete end-user systems on a single chip possible. This massive level of integration makes modern multi-core chips all pervasive in domains ranging from weather forecasting, astronomical data analysis, and biological applications to consumer electronics and smart phones. NoCs have emerged as communication backbones to enable a high degree of integration in multi-core SoCs. Despite their advantages, an important performance limitation in traditional NoCs arises from planar metal interconnect-based multi-hop communications, wherein the data transfer between far-apart blocks causes high latency and power consumption. The latency, power consumption, and interconnect routing problems of NoCs can be simultaneously addressed by replacing multi-hop wired paths with high-bandwidth single-hop long-range wireless links. In this talk, we will present design of the millimeter (mm)-wave wireless NoC architectures. We will present detailed performance evaluation and necessary design trade-offs for the small-world wireless NoCs with respect to their conventional wireline counterparts. We will also discuss different media access control (MAC) mechanisms and routing protocols used for Wireless NoCs so far. To sustain the predicted performance, a deadlock-free routing algorithm must be designed. The routing protocol also needs to be simple without incurring excessive power, area and latency overheads. We will finish this presentation by discussing the thermal and power management policies suitable for Wireless NoCs.
