Abstract

Multiprocessor System-on-Chip (MPSoC) is an attractive solution to provide a high performance computing required by the new applications are growing exponentially such as in multimedia applications. However, the communication between processors' cores presents a serious problem in the era of MPSoC. The network on chip (NoC) is presented as a promising solution is acknowledged that it is still limited with increasing data exchange. Moreover, the traditional NoC faces two main problems: the bandwidth and energy consumption. However, a new technology in MPSoC, namely,optical network-on-chip (ONoC) has been introduced which uses optical communication. In addition, wavelength division multiplexing (WDM) is exploited in ONoC to reach a high rate of bandwidth. Nevertheless, the ONoC components inducing crosstalk noise to the optical signal and direct effect the signal-to-noise ratio(SNR). In this article, new system has been proposed to address these impairments in the network in order to detect and monitor crosstalk noise in WDMbased ONoC. The register-transfer level (RTL) hardware design and implementation of this system can result in high reliability, scalability and efficiency with running time less than 20 ms.
