Domain-specific front-end for virtual system modeling

The complexity of software and hardware in embedded systems has risen rapidly due to convergence of diverse applications and adoption of multicore technologies. Consequently, the abstraction level of system design, modeling and exploration needs to be raised to manage the complexity. The Y-chart approach, typically applied in the system-level performance evaluation, allocates/maps a model of application on a model of execution platform and the resulting system model is simulated to obtain performance data. In this work, Domain-Specific Modeling (DSM) has been adopted as means of raising the abstraction level for building, composing, configuring and checking of highlevel models in the virtual system performance modeling and simulation approach, called ABSOLUT. Domain-Specific Languages (DSL) were defined to serve as front-ends for application workload, platform and allocation modeling using the MetaEdit+ tool. The results are demonstrated with a video player case example. First experiences indicate that in performance evaluation related tasks the modeling productivity, model management and ease of learning have improved.
