Many previously proposed interface models for composability analysis of hierarchical scheduling are overhead-unaware, which is unsafe for real systems. This paper proposes an overhead-aware schedulability analysis to guarantee temporal partitioning among real-time applications/components hosted on a multicore platform. First, a new interface model and the method to generate an interface for a given component is proposed. Each interface has a tunable parameter d (degree) that can balance between abstraction and accuracy in capturing each component's task-level timing constraints. Second, the problem of constructing an overhead-aware system-level schedule of all the components is addressed. The system designer has the flexibility to select parameters (e.g., allocated processor bandwidth) for each component such that overhead (e.g., preemptions across partitions) is minimized. Third, a slack distribution algorithm to reduce various overhead is proposed and its effectiveness is evaluated using randomly generated interface sets and also using workload of a real space-borne application provided by RUAG Space Sweden AB. |
