Multilevel MPSoC Performance Evaluation Using MDE Approach

In this paper, we present a multilevel framework for multiprocessor systems-on-chip (MPSoC) that makes fast simulation and performance evaluation possible in the design flow. In this framework, we use the model-driven engineering (MDE) approach within the GASPARD design flow. Two target simulation models at the cycle accurate bit accurate (CABA) and the timed programmers view (PVT) abstraction levels are defined. In addition, in this paper, a set of meta-models corresponding to the simulation models and the deployment phase are also detailed. The latter meta-model allows hardware component refinement with performance parameters specification. Experimental results show the usefulness of our framework to decrease the design complexity of MPSoC architecture and to acheive high speedup simulation with a negligible estimation error margin
