Recursive Wavelength Routed Optical Network for Optical Network-on-Chips

Abstract— The wavelength routed optical network (WRON) is a promising optical interconnection architecture that can be integrated into a System-on-Chip (SoC) with an intention to replace traditional wire-connected on-chip micro-networks which pose severe bandwidth limitations on future super large SoC chips. In this paper, we present a new recursive architecture, the Recursive Wavelength Routed Optical Network (RCWRON) based on the WRON, and provide the solution to the routing problem on RCWRON based on two of three routing parameters (the source node address, the destination node address and the routing wavelength). Compared with WRON, RCWRON has many advantages, such as its recursive structure and fault tolerance capability.
