Optimizing Resource Usage in Component-Based Real-Time Systems

Conference/Workshop Paper


the 8th International Symposium on Component-based Software Engineering (CBSE8)


The embedded systems domain represents a class of systems that have high requirements on cost efficiency as well as run-time properties such as timeli¬ness and dependability. The research on component-based systems has produced component technologies for guaranteeing real-time properties. However, the issue of saving resources by allocating several components to real-time tasks has gained little focus. Trade-offs when allocating components to tasks are, e.g., CPU-over¬head, footprint and integrity. In this paper we present a general approach for allo¬cating components to real-time tasks, while utilizing existing real-time analysis to ensure a feasible allocation. We demonstrate that CPU-overhead and memory consumption can be reduced by as much as 48% and 32% respectively for indus¬trially representative systems.
