This paper presents an abstract system-level modeling framework, called {ARTS,} to support the MPSoC designers in modeling the different layers and understanding their causalities. While others have developed tools for static analysis and modeled limited correlations (processor-memory or processor-communication), our model captures the impact of dynamic and unpredictable {OS} behaviour on processor, memory and communication performance. In particular, we focus on analyzing the impact of application mapping on the processor and memory utilization taking the on-chip communication latency into account. A case-study of real-time multimedia application consisting of 114 tasks on a {6-}processor platform for a handheld terminal shows our frameworks co-exploration capabilities." }
