Implementation of qos aware q-routing algorithm for network-on-chip

Abstract

The objective of this paper is to implement QoS aware Q-routing algorithm for providing different level of Quality-of-Service (QoS) such as Best Effort (BE) and Guaranteed Throughput (GT) in Network-on-Chip. In this paper, a novel scheme which contrast the performance of Q-routing with the well known XY routing strategy in context of QoS in Network-on-Chip (NoC) is presented. Simulation study with discrete event, cycle accurate, Network-on-Chip simulator NIRGAM reveals that Q-routing proves to be superior to the non-adaptive routing algorithm for both type of traffic BE and GT. The paper explores the performance of the network for different values of bandwidth reserved for GT traffic. © 2009 Springer Berlin Heidelberg.
