Abstract:

Networks – on – Chip (NoCs) have gained popularity as the most dominant interconnect paradigm for many-core and accelerator- rich Systems-on-Chip (SoCs). Among the many topologies available, the two-dimensional (2D) mesh topology serves as the canonical architectural template. This survey presents a concise review of 2D mesh–based NoC architectures.

Routing algorithms are classified into deterministic, partially adaptive, fully adaptive, and non-minimal categories. A concise survey of popular routing strategy till date has been discussed for mesh NoC topology along with the advantages and disadvantages of the routing strategy.
