“…Because there are so few nodes that can convert wavelengths, there is less chance of a network breakdown. The performance can be enhanced by positioning these converters ideally using heuristic and metaheuristic techniques, according to studies on the location of wavelength converters [9], [10], and [11]- [14]. In order to find wavelength convertible routers for partial wavelength conversion, least blocking probability first (MBPF) is used [12].…”

We present an optical routing and wavelength assignment (RWA) technique for the best placement of the wavelength converters. The wavelength converter placement was considered independently at the complete nodes and partial nodes. In comparison to existing approaches, our technique performs better and requires fewer wavelength converters to get the required performance. As much as 7%, the likelihood of blocking is decreased. The study also demonstrates that the top four nodes have the biggest influence over the blocking performance of the network. It is clear that placing the converters in the right location is just as crucial to improving performance as simply adding more converters.

“…Compared with the traditional electric network-on-chip, it has lower power consumption, low end-to-end communication delay, and higher bandwidth [5][6][7][8]. Although ONoC can realize highperformance inter-core communication, it lacks an optical buffer and supports a limited number of wavelengths [9,10]. These challenges need to be addressed in order to design a high-performance ONoC.…”

Optical network-on-chip (ONoC) is an emerging architecture to realize high-performance and low power consumption for many-core processors. Multicast in ONoC is a vital communication pattern widely used in parallel computing and computational genomics. This paper proposes an efficient scheme for multiple multicast requests in ONoC. Firstly, we design an algorithm to construct two trees for two multicasts without conflicting edges in a mesh topology, and it only uses one wavelength. We propose a graph to represent the relationship between each multicast. Secondly, a group-based wavelength assignment scheme is designed to assign wavelengths for multiple multicasts. Finally, we used data analysis to extract helpful simulation results to form conclusions. The results indicate that our algorithm is superior to other tree-based schemes in communication latency and wavelength number usage.

“…For multi-core processors, two dimensional (2D) ONoCs are designed. The optical routers for 2D ONoC architecture using MRR have been proposed in [8][9][10][11][12][13][14][15]. The number of cores required on-chip are increasing, and so complexity of the on-chip interconnects are increasing.…”

The interconnection network is very influential in Multiprocessor system-on-chip (MPSoC) performance. Due to low power efficiency and high latency, conventional interconnects are replaced by electrical networks on-chip (ENoC). However, ENoCs cannot gratify the bandwidth, latency and loss requirements within the available power budget of optical integrated circuits. The reasons being restricted bandwidth, extended delay, and reasonably high power consumption. So, ENoC are being replaced by optical networks-on-chip (ONoC). ONoC has emerged as a promising substitute to provide greater bandwidth, low latency and low power ingestion in MPSoCs. Number of cores required on-chip is increasing which leads to demand of multilayer multi-core processors. Three dimensional (3D) ONoC has become essential for such multilayer multi-core processors. For 3D ONoC, in this paper we have proposed 6x6 non-blocking optical router using micro-ring resonator (MRR) with less number of waveguide crossings and waveguide bendings. Phoenix software is used to simulate proposed optical router. Insertion loss of proposed optical router is lowest among existing non-blocking optical routers of 3D ONoC.
