Qualitative Analysis of 3D Routing Algorithms in 3×3×3 Mesh NoC Topology Under Varying Load in Bio-SoC

Abstract

This article presents a qualitative analysis of a 3D routing algorithm in a 3×3×3 mesh NOC topology. The effect of load variation on throughput, total energy, and maximum delay for different types of routing is observed. The simulation was performed on an Access NOXIM network-on-chip simulator under random traffic conditions. The research involves quality parameters like total packets received, total received flits, global average delay (cycles), global average throughput (flits/cycle), throughput (flits/cycle/IP), max delay (cycles), total energy (J), average power (J/cycle), average power per router (J/cycle), and average waiting time in each buffer. In this article, it was observed after comparing all the routing techniques against the mention parameters the XYZ routing techniques was found perform better followed by West first, and North last, while poor performance was observed against odd-even, negative first, and fully adaptive.
