Performance evaluation of virtual channel flow control in centralized and distributed networks for system on chip

On-chip communication is one of the main challenges introduced to high level integrated system-on-chip design. To address complexity and wiring challenges, network-on-chip has been proposed as a prominent solution capable of providing a reliable and efficient communication platform. Accordingly, network design counts as a key parameter that defines the overall system performance. In this paper, we propose a network design that integrates centralized routers in distributed networks. Our results are compared to distributed networks of different sizes using a variety of synthetic traffic patterns and benchmarks.
