“…When an IP core has N ring rings to communicate with other IP cores, the interface of this core has N ring +1 micro-rings. Thus, according to comparing the number of micro-rings in different network with different optical switches, crossbar, cygnus [13], crux [16], switches from [14], [15] and [17]. From the table in Table 1, we can see that the number of micro-ring optical switches of multi-ring is less than that in other optical switches.…”

SUMMARYRing-based topology is popular for optical network-onchip. However, the network congestion is serious for ring topology, especially when optical circuit-switching is employed. In this paper, we proposed an algorithm to build a low congestion multi-ring architecture for optical network-on-chip without additional wavelength or scheduling overhead. A network congestion model is established with new network congestion factor defined. An algorithm is developed to optimize the low congestion multi-ring topology. Finally, a case study is shown and the simulation results by OPNET verify the superiority over the traditional ONoC architecture.

“…In some other hybrid architectures such as [22], local communications are carried out by an electrical network, whereas long distance communications utilize optical links. Ahmed et al [23] exploit non-blocking photonic switches as well as light-weight electronic routers to decrease the latency and power overheads of hybrid architectures. García-Guirado et al [24] propose a set of policies to manage hybrid networks consisting of ring-based photonic and electrical mesh sub-networks.…”

Advances in CMOS-compatible photonic elements have made it plausible to exploit nanophotonic communications to overcome the limitations of traditional NoCs. Amongst various proposed nanophotonic architectures, optical crossbars have been shown to provide high performance in terms of bandwidth and latency.In general, optical crossbars provide a vast volume of network resources that are shared among all the cores within the chip. In this paper, we present a fair and efficient admission control mechanism for shared wavelengths and buffer space in optical crossbars. We model buffer management and wavelength assignment as a utility-based convex optimization problem, whose solution determines the admission control policy. Thanks to efficient convex optimization techniques, we obtain the globally optimal solution of the admission control optimization problem by using simple and yet efficient iterative algorithms. We cast our solution procedure as an iterative algorithm to be implemented a central admission controller. Our experimental results corroborate the gain that can be obtained by using such an admission controller to manage the shared resources of the system. Furthermore, they confirm that the proposed admission control algorithm works well for various traffic patterns and parameters, and evinces a tractable scalability with increase in the number of cores of the crossbar.

“…The characteristics of low delay, high bandwidth, and low power consumption can effectively solve the ongoing bottlenecks of on-chip communication [5][6][7]. In the design of on-chip optical networks, the communication architecture is often structured based on optical circuit switching, which causes a blocking problem when the communication links are occupied by different data flows, leading to lower throughput and higher energy consumption [8,9]. The wavelength division multiplexing (WDM) technology enables optical signals of multiple wavelengths to be transmitted in the same waveguide, which avoids blocking and effectively improves the communication performance [10][11][12].…”

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.
