Real-time multiprocessor locks with nesting: optimizing the common case

In prior work on multiprocessor real-time locking protocols, only protocols within the RNLP family support unrestricted lock nesting while guaranteeing asymptotically optimal priority-inversion blocking bounds. However, these protocols support …

Thermal-aware task allocation and scheduling for periodic real-time applications in mesh-based heterogeneous NoCs

With continuous technology scaling, the power density and hence the temperature of Network-on-Chip (NoC) may increase rapidly. This in-turn degrades the performance of the chip and increases the chances of creating thermal hot-spots. Task …


Cache-conscious off-line real-time scheduling for multi-core platforms: algorithms and implementation

Most schedulability analysis techniques for multi-core architectures assume a single worst-case execution time (WCET) per task, which is valid in all execution conditions. This assumption is too pessimistic for parallel applications running on …


Priority-based scheduling of mixed-critical jobs

Modern real-time systems tend to be mixed-critical, in the sense that they integrate on the same computational platform applications at different levels of criticality (e.g., safety critical and mission critical). Scheduling of such systems is a …

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.
