NOC: QOS Metrics Modelling And Analysis Based On Dynamic Routing

Abstract

Increasing heterogeneous software and hardware blocks constitute complex ICs known as System on Chip (SoC). These blocks are conceived as intellectual property (IP) cores. Designers are developing SoCs by using IP cores reuse, which include interconnection architecture and interface to peripheral devices.Because of the SoC growing complexity, some researchers tend to concentrate more on the communication rather than the computation aspect. This area of research has leading to the Network on Chip (NoC) Concepts.The research domain of NoC has many applications needing high communication performances. Therefore NoC offers attractive solutions to these applications.One of the goals of NoC technology is to maintain a required Quality of Service (QoS), defined in terms of acceptable parameters values.This paper proposes a presentation of QoS metrics model based on QoS parameters such as Endto-End Delays (EED) and throughputs (Thp), for different applications. This study is based on dynamic routing simulation of a 4x4 mesh NoC behaviour under three communications processes namely TCP, VBR and CBR.
