On improving best-effort throughput by better utilization of guaranteed throughput channels in an on-chip communication system

Abstract

It is possible to concurrently run multiple applications on IP-core based SoC built using Network on Chip (NoC) paradigm. Some applications require predictable and guaranteed on-chip communication performance. In this paper we propose a new approach for using underutilized reservation of guaranteed throughput (CT) traffic to improve the performance of best effort (BE) traffic. We have modeled our scheme for a mesh topology NoC on a simulation platform. The results show that the proposed scheme leads lo significant improvement in BE performance.
