A real-time execution performance agent interface to parametrically controlled in-kernel pipelines

This paper presents work-in-progress to build a confidence-based in-kernel pipeline execution performance interface to a fixed priority deadline monotonic scheduler. The interface provides performance-controlled pipeline execution, allowing applications to specify expected execution times, negotiate desired deadline confidence and to configure and control pipelines. The confidence-based scheduling interface and in-kernel pipeline are being evaluated on an unoccupied air vehicle incorporating digital control, continuous media, and event-driven pipelines
