“…For the communication between IP cores in different clusters, the packets are transmitted in the waveguides in the form of light. This cluster architecture has three main advantages: (1) Optical communication in short distances does not have a prominent advantage compared to electrical communication [28]. Therefore, an electronic crossbar is used to route the data packets in short distance with a small delay and low energy consumption.…”

Wavelength division multiplexing (WDM) mesh-based optical network on chip (ONoC) have recently received considerable attention due to their regular topology and higher throughput. However, available wavelengths are finite resources. Thus, to minimize the number of wavelengths, this letter proposes an efficient WDM mesh-based ONoC mapping approach, which is based on a particle swarm optimization algorithm. Experimental results reveal that our proposal has a positive effect in minimizing the number of wavelengths needed compared to random mapping. The tradeoff between the number of wavelengths and the network size is also investigated, and it is found that increasing the network size can reduce the number of wavelengths needed. Meanwhile, the experiments show that the structure has better network performance and less communication resource utilization.

“…Also, in [18], a canonical macrochip computing system has been studied. Structures based on 3-D mesh ONoC have been proposed in other studies in [19][20][21] where algorithms for routing in these structures have been introduced in these structures. 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.…”

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.

“…Photonic Network-on-Chip (PNoC) [1][2][3][4][5][6][7] is a novel concept enabling ultra-high communication throughput in the terabits per second range, low power and low communication latency. When powered with a wavelength division multiplexing (WDM) scheme, multiple parallel optical streams of data are concurrently transferred through a single on-chip waveguide.…”

“…Using Dense Wavelength Division Multiplexing (DWDM), up to 64 (and theoretically more) separate wavelengths can be multiplexed into a light stream transmitted on a single waveguide [16]. In conventional hybrid PNoC systems [1,3,5,[17][18][19][20], the source node first issues a path configuration packet, which includes destination address information and other additional control information, via a copper-based electrical link. The configuration packet is routed via an Electric Control Network (ECN), reserving the photonic switches and channels along the path for the photonic message.…”

Future high-performance embedded and general purpose processors and systems-on-chip are expected to combine hundreds of cores integrated together to satisfy the power and performance requirements of large complex applications. As the number of cores continues to increase, the employment of low-power and high-throughput on-chip interconnect fabrics becomes imperative. In this work, we present a novel mesh-based photonic on-chip interconnect, named PHENIC-II, for future high-performance many-core systems. The novel architecture is based on an energy-efficient non-blocking photonic switch and a contention-aware routing algorithm. Simulation results show that the proposed system provides better bandwidth and energy efficiency when compared to conventional hybrid photonic NoC systems.
