Performance Analysis of NoC and WiNoC in Multicore System Architectures

Abstract Wireless network-on-chip has emerged as an innovative and effective solution to meet the growing demands for efficient data communication in multi-core processors. It offers an alternative approach to overcoming scalability challenges in communication systems. This study offers an in-depth performance assessment of network-on-chip and wireless network-on-chip multicore system architectures in the context of a 64-core and 256-core system. The analysis includes four synthetic traffic patterns—random, shuffle, butterfly, and transpose—giving a detailed overview of how each impacts system performance. Key metrics such as data transmission delay, network throughput efficiency, and energy consumption were thoroughly analyzed. To support our conclusions, simulations were conducted on 64-core and 256-core for NoC and WiNoC multicore system. The results highlight the effectiveness of the WiNoC multicore system design, demonstrating its advantage in network performance based on the simulations carried out with Noxim. WiNoC’s enhanced ability to handle higher traffic loads and achieve lower latency across all traffic profiles showcases its advantage over the traditional NoC setup.
