Loss-Aware Router Design Approach for Dimension- Ordered Routing Algorithms in Photonic Networks-on-Chip
Photonic-Network-on-chip (PNoC) has been proposed as a promising solution for the communication infrastructure of Chip Multiprocessors (CMPs) and as a solution to overcome the constraints in traditional NoCs. Photonic NoCs provide the opportunity of increasing both the bandwidth and the number of cores significantly, and can improve performance and the cost parameters of CMPs. In this paper, a designing approach for a photonic router has been proposed in order to reduce insertion loss in photonic NoCs, which can in turn increase network throughput, since it uses more parallel wavelengths. It has also led to the design of a router structure exclusively for XY routing algorithm. The proposed router shows an improvement of up to 52% in insertion loss, when compared to other proposed routers.
