M8NoC: An 8-degree mesh-based NoC architecture

In multicore systems, low transmission delay and high throughput are essential to fully harness the computational power offered by tens or hundreds of cores. In this paper we present a new NoC architecture (M8NoC) by devising changes to the topology and routing of the simple mesh network. The changes allow overcoming some limitations of the mesh network by decreasing the diameter, decreasing the average distance and increasing the bisection width. Preliminary analytical investigation have shown potential enhancements in performance and reliability. Namely, the M8NoC achieves higher throughput and lower latency compared to its mesh, torus and spidergon counterparts.
