Achieving Industrial Strength Timing Predictions of Embedded System Behavior
This paper discusses why the extensive scientific results on predicting embedded systems temporal behavior never, or very seldom, reaches the industrial community. We also point ou...

Maximizing the Fault Tolerance Capability of Fixed Priority Schedules
Real-time systems typically have to satisfy complex requirements, mapped to the task attributes, eventually guaranteed by the underlying scheduler. These systems consist of a mix ...

Fine-Grained Task Reweighting on Multiprocessors
We consider the problem of task reweighting in fair-scheduled multiprocessor systems wherein each task’s processor share is specified as a weight. When a task is reweighted, a ...

Branch Target Buffers: WCET Analysis Framework and Timing Predictability
—One step in the verification of hard real-time systems is to determine upper bounds on the worst-case execution times (WCET) of tasks. To obtain tight bounds, a WCET analysis h...

Deterministic and Statistical Deadline Guarantees for a Mixed Set of Periodic and Aperiodic Tasks
Current hard real-time technologies are unable to support a new class of applications that have real-time constraints but with dynamic request arrivals and unpredictable resource r...
