NoC generation of an optimal memory distribution for multimedia systems

Abstract

In this paper a topological analysis of different IP distributions focusing on optimal memory placements in regular 2D-Meshes has been performed. As case study, a real MPEG-4 decoder implementation with three memories was chosen. In order to study the influence of memories in the topology of the network, Arteris NoCexplorer tool was used. The results inferred from the experiments show how the performance of a multimedia system can be improved if memories are properly located within a NoC. Furthermore, the present work serves to validate the use of Arteris NoCexplorer for simulating and modelling complex NoC based designs. In addition, a methodology for determining the best IP distribution in terms of latency and throughput is presented and its feasibility is demonstrated.
