Applying fixed-priority preemptive scheduling with preemption threshold to asynchronous event handling in the RTSJ
The primary goal of asynchronous event handlers (handlers for short) in the Real-Time Specification for Java (RTSJ) is to have a lightweight concurrency mechanism. The emphasis here is on ‘lightweightness’ which should be achieved by having fewer real-...
Extending the concurrency model of the real-time specification for Java
The current RTSJ (Real-Time Specification for Java) threading model is dualized: a programmer has to decide between the high predictability offered by the region-based model and the flexibility offered by the garbage collection. So far, there is no ...
Replicating real-time garbage collector
Real-time Java is becoming a viable platform for real-time applications, bringing new challenges to a garbage collector. A real-time collector has to be incremental as not to cause deadline misses by suspending an application for too long. In particular,...
Quantitative dynamic-memory analysis for Java
Space- and time-predictability are hard to achieve for object-oriented languages with automated dynamic-memory management. Although there has been significant work to design APIs, such as the Real-Time Specification for Java (RTSJ), and to implement ...
A family of real-time Java benchmarks
Java is becoming a viable platform for real-time computing. There are production and research real-time Java VMs, as well as applications in both the military and civil sectors. Technological advances and increased adoption of real-time Java contrast ...
