“…First-order noise Infinite-order noise We followed the process in section VI-E. First we solved 17 linear systems (one per wavelength) to calculate the insertion loss of all 240 signals. Each signal is sent into the network with the minimum amount of energy required to overcome its insertion loss considering a demodulator sensitivity of −20 dBm [23]. We then solved 17 linear systems again to calculate the signal and noise energy levels in the network.…”

Optical Networks-on-Chip (ONoCs) are becoming more and more appealing due to rising network requirements in integrated circuits. One important aspect in ONoC design is the amount of crosstalk generated by the network because crosstalk and Signal-to-Noise Ratio (SNR) are strong limiting factors to network scale and performance. Calculation of crosstalk is thus essential for effective ONoC design. Motivated by this fact, we developed a new general linear algebra based method to calculate the steady-state of any system obeying a simple set of rules. We prove that ONoCs follow these rules and show how this general method can be applied in the particular case of ONoCs to calculate accurate first-order and infinite-order crosstalk and SNR results for any ONoC network.

“…For each pair of communicating nodes in the network, a dedicated signal path is statically reserved at design time, so that the initiator node can transmit data to the target node at any time, regardless of other on-chip communications in progress. In this manner, WRONoCs avoid the latency and energy overhead for arbi- tration, and are thus especially suitable for applications that require time predictability and/or performance guarantees [5], [6].…”

Enabled by recent development in silicon photonics, wavelength-routed optical networks-on-chips (WRONoCs) emerge as an appealing next-generation architecture for the communication in multiprocessor system-on-chip. WRONoCs apply a passive routing mechanism that statically reserves all data transmission paths at design time, and are thus able to avoid the latency and energy overhead for arbitration, compared to other ONoC architectures. Current research mostly assumes that in a WRONoC topology, each initiator node sends one bit at a time to a target node. However, the communication parallelism can be increased by assigning multiple wavelengths to each path, which requires a systematic analysis of the physical parameters of the silicon microring resonators and the wavelength usage among different paths. This work proposes a mathematical modeling method to maximize the communication parallelism of a given WRONoC topology, which provides a foundation for exploiting the bandwidth potential of WRONoCs. Experimental results show that the proposed method significantly outperforms the state-of-the-art approach, and is especially suitable for application-specific WRONoC topologies.1 i.e., λr = n eff L m , where λr is the resonant wavelength, n eff is a constant refractive index, L is the round trip length of the MRR, and m is a natural number.
