Pareto-Based Application Specification for MP-SoC Customized Run-Time Management

In an MP-SoC environment, a customized run-time management should be incorporated on top of the basic OS services to globally optimize costs (e.g. energy consumption) across all active applications, according to constraints (e.g. performance, user requirements) and available platform resources. To that end, we have proposed a Pareto-based approach combining a design-time application mapping and platform exploration with a low-complexity run-time manager. This allows to alleviate the OS in its run-time decision making and to avoid conservative worst-case assumptions. In this paper, we focus on the characterization of the Pareto-based application specification, resulting from our design-time exploration. This specification is essential as input for our run-time manager. A representative video codec multimedia application, simulated on our MP-SoC platform simulator, is used as case study. For the resulting Pareto-based specification, both binary size and performance overhead is negligible
