Performance Analysis of Mesh-based NoC’s on Routing Algorithms

Abstract

The advent of System-on-Chip (SoCs), has brought about a need to increase the scale of multi-core chip networks. Bus Based communications have proved to be limited in terms of performance and ease of scalability, the solution to both bus – based and Point-to-Point (P2P) communication systems is to use a communication infrastructure called Network-on-Chip (NoC). Performance of NoC depends on various factors such as network topology, routing strategy and switching technique and traffic patterns. In this paper, we have taken the initiative to compile together a comparative analysis of different Network on Chip infrastructures based on the classification of routing algorithm, switching technique, and traffic patterns. The goal is to show how varied combinations of the three factors perform differently based on the size of the mesh network, using NOXIM, an open source SystemC Simulator of mesh-based NoC. The analysis has shown tenable evidence highlighting the novelty of XY routing algorithm.

Thermal-aware directional and adaptive routing algorithm for 3D network-on-chip

“…3D network-on-chip (3D NoC) based designs are expected to offer improved performance while using fewer data transfer connections and consuming less power [1], [2]. In conventional NoC architecture, each tile comprises a network interface, processing element (PE), and a router [3], [4]. A high switching activity in routers is responsible for thermal hotspots in NoC [5].…”
