ONC3: All-Optical NoC Based on Cube-Connected Cycles with Quasi-DOR Algorithm

This paper proposes a nanophotonic Network-on-Chip architecture based on the traditional Cube-Connected Cycles topology (CCC), which is named as ONC3. We also suggest a contention-free quasi-Dimension-Order-Routing algorithm for the proposed structure. Compared to the previous 2D layouts, our novel scheme lessens the crosstalk parameter of the insertion loss and consequently, the power consumption. Besides, the router structure is area-efficient. On the other hand, optical destination checking supersedes electrical resource reservation, with utilizing passive wavelength routing method and Wavelength Division Multiplexing scheme, simultaneously. The efficiency of the proposed architecture, in terms of the essential NoC parameters such as delay and power consumption, is investigated through simulation-based experiments and is compared with electrical CCC and Torus topologies, as well as the existing ONoCs such as the optical crossbar and ?-router in various synthetic traffic patterns.
