To quantitatively measure quality of service (QoS) in Network on Chip (NoC), several related aspects of the network service are often considered, such as end to end delay (EED), Throughput (Thp), Packet loss rate (PLR), etc. However, until now, no standard method of performance measurement and fewer techniques have been used to provide its definition. In fact, few papers have developed different methods to modelize QoS in NoC and provided an efficient and flexible way to monitor QoS. The

... lity of our approach is based on a proposition of a QoSintellectual property module in NoC architecture to improve network performances. We implement an approach of QoS metrics modeling for NoC, using Analytic Hierarchy Process (AHP) on multi-parameter and multi-application for 4×4 mesh NoC environment. The results have shown that our QoS modeling approach is proven successful in providing a quantifiable representation. Therefore, QoS arbiter module interacts with other routers, the link utilization is balanced and network performance improved.
