Reliable mode changes in real-time systems with fixed priority or EDF scheduling
Abstract—Many application domains require adaptive realtime embedded systems that can change their functionality over time. In such systems it is not only necessary to guarantee ...

Semi-partitioned Fixed-Priority Scheduling on Multiprocessors
This paper presents a new algorithm for fixed-priority scheduling of sporadic task systems on multiprocessors. The algorithm is categorized to such a scheduling class that quali...

WCET-Centric Software-controlled Instruction Caches for Hard Real-Time Systems
Cache memories have been extensively used to bridge the gap between high speed processors and relatively slower main memories. However, they are sources of predictability problems...

Virtual Simple Architecture (VISA): Exceeding the Complexity Limit in Safe Real-Time Systems
Meeting deadlines is a key requirement in safe realtime systems. Worst-case execution times (WCET) of tasks are needed for safe planning. Contemporary worst-case timing analysis t...

Schedulability Analysis for Non-Preemptive Tasks under Strict Periodicity Constraints
Real-time systems are often designed using preemptive scheduling to guarantee the execution of high priority tasks. For multiple reasons there is a great interest in exploring non...
