Abstract

One of the key elements in Multi-Processor Systems-on-Chip (MPSoC) design is to select the optimal on-chip interconnect architecture, in order to maximize the overall system performance.This paper proposes a flexible MPSoC platform, designed for a target application, which allows customizing the interconnect by selecting various architectures. It allows fast building of executable models from architecture specifications and performance evaluation using the cycle-accurate cosimulation.We experimented a DivX encoder application with three different interconnects: DMS (Distributed Memory Server), AMBA bus and Octagon Network-on-Chip (NoC). The simulation results relative to performance metrics such as, average latency, throughput and execution time allowed to compare these different interconnect architectures, to verify the application real-time constraints and to propose further optimizations.
