Review of NoC-based FPGAs architectures

Abstract

Nowadays, FPGAs serve as Fields Programmable Systems on Chip (FPSoC) and are widely used to implement computationally intensive world applications. As the number of components in FPSoCs increases, the interconnect schemes based on Network on Chip (NoC) approach are increasingly used to overcome the problems of traditional bus based and point-to-point interconnect scheme. In this paper, we review several designs based on their contributions, architectures, implementations and future works. We also made our comparison between three of these routes to analyze the effect of varying the number of Virtual Channels (VCs), flit data width and buffer depth on the operating frequency, Logic Look-Up Tables (LUTs) and registers to help choosing the appropriate NoC based on system requirements.
