While integration of configurable components, such as soft processors, in MPSoC design enables further system adaptation to application needs, supporting system level tools need to provide an environment for systematic and efficient configuration exploration. This paper presents a multi-layer configuration exploration framework for streaming applications on MPSoCs. We introduce a novel Configuration Exploration Tree (CET) for configuration selection per processor. Integrated in a system-level design environment, our CET enables efficient and fully automatic exploration of processor configurations in MPSoC. The proposed CET supports the fast evaluation of feasible configurations by simulation at highest levels of abstraction. In addition, assuming monotonous impact of configuration values on system throughput, we use an ordering among the nodes in the CET to minimize necessary simulations. Our exploration efficiently finds all feasible configurations for a given constraint. I.
