Abstract

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.
