High performance hybrid NoCs design with wireless/RF-I

According to the International Technology Roadmap for Semiconductors (ITRS), improving characteristics of metal wires will no longer satisfy performance requirements for future large scale MPSoC systems, and new interconnect paradigms are needed. Different revolutionary approaches like optical interconnect, Radio Frequency Interconnect (or RF-I), wireless interconnects with CMOS ultra wide band (UWB) technology have been explored. The hybrid hierarchical architecture with Wireless/RF-I backbones is more cost-efficiency and feasible due to the advantages in CMOS compatibility compared with other alternative interconnects, and has become one of the mainstreams of CMP architectures. However, how to design an efficient HNoCs is a new challenge. This work provides the architecture design flow of the HNoCs with wireless/RF-I, and explores the key problems in the architecture design from the perspectives of topology, resource management strategy and routing problems, which are different with traditional metallic interconnections.
