Feasibility of on-line speed policies in real-time systems

We consider a real-time system where a single processor with variable speed executes an infinite sequence of sporadic and independent jobs. We assume that job sizes and relative deadlines are bounded by C and $$\varDelta $$Δ respectively.

Optimal scheduling of measurement-based parallel real-time tasks

In this work we consider a measurement-based model for parallel real-time tasks represented by the work and span parameters of directed acyclic graphs, with different bounds for nominal and overload scenarios. We address the corresponding …

Über diese Zeitschrift

The journal Real-Time Systems publishes papers, short papers and correspondence articles that concentrate on real-time computing principles and applications. The contents include research papers, invited papers, project reports and case studies, standards and corresponding proposals for general discussion, and a partitioned tutorial on real-time systems as a continuing series.

The range of coverage is broad, including requirements engineering, specification and verification techniques, design methods and tools, programming languages, operating systems, scheduling algorithms, architecture, hardware and interfacing, dependability and safety, distributed and other novel architectures, wired and wireless communications, wireless sensor systems, distributed databases, artificial intelligence techniques, expert systems, and application case studies.

Real-time systems find application in command and control systems, process control, flight control, avionics, defense systems, vision and robotics, pervasive and ubiquitous computing, and an abundance of embedded systems.
