WIP : Feasibility analysis of real-time periodic multi-phase tasks on unrelated multiprocessor platforms

Résumé

Modern processing architectures, such as Systemon-Chip (SoC) feature heterogeneous processors categorized as unrelated platforms in the real-time scheduling theory. Real-time tasks can be decomposed into subtasks called phases, each with a different execution rate depending on the processing unit it is assigned to. This preliminary work studies the feasibility of scheduling periodic real-time tasks with multiple phases on unrelated platforms. Initially, we apply an existing optimal analysis technique based on linear programming, designed for mono-phase tasks. This approach proves to be non-optimal in this context. Thus, we introduce a more fine-grained formulation and let formal and experimental validation for future work.
