“…Furthermore, in [21], OPNET is used to provide a simulation environment for investigating average delay and data packet loss rate in 2D and 3D mesh ONoCs. Moreover, a crosswalk aware routing algorithm for Benes ONoC is proposed in [22]. In another study [23], a 3D Torus ONoC along with an adaptive routing algorithm has been proposed for improving the performance of 3-D ONoCs.…”

The need for more scalability in design on one hand and the occurrence of latency and high power consumption in communications between distant cores on the other hand are considered as the most common challenges which networks on chip encounter. Today, wireless network on chip (WiNoC) is regarded as a novel proposed approach in which wireless links are shortcuts for the fast data transmission between distant cores. However, the presence of Wireless routers (WRs) in WiNoC increases the cost and area. Thus, finding an optimal structure for communicating between cores is essential. In this paper, genetic algorithm (GA) and simulated annealing (SA) are compared with each other under different traffic patterns to find the best positions of WRs. The results obtained from the simulations of this study indicate that GA has higher efficiency than SA. Furthermore, the resulting structure has fewer WRs and relatively desirable performance.

“…At router level, the research in [3] indicates that the optical router design has a great influence on SNR performance of ONoC. At network level, researchers propose a crosstalk aware routing algorithm for Benes ONoC to relieve the crosstalk problem [9]. But the algorithms in [9] is proposed for single wavelength ONoC architectures.…”

Optical Network-on-Chip (ONoC) is a promising on-chip communication architecture for future many-core systems due to its high-performance and energy-efficient characteristics. However, the crosstalk problem is an obstacle to the realization of ONoC. In large scale ONoC, the crosstalk noise considerably reduces data transmission reliability via the signal-to-noise ratio (SNR), and limits the scalability of ONoC. In this letter, we propose a crosstalk-aware wavelength assignment (CWA) method to mitigate the crosstalk problem. Analyses results indicate that our CWA method significantly improves the worst-case SNR and allows a higher network scalability.

In [106] The fundamental limits for the number of WDM channels and power per channel when using building blocks that include silicon waveguides, silicon microring modulators and filters were described by K. Preston, et al in [108].…”
