Thread-Local Scope Caching for Real-time Java

There is increasing convergence between the fields of parallel and embedded computing. The demand for more functionality in embedded devices means that complex multicore architectures will be used. In order to promote scalability and obtain predictability, on-chip processor-local private memory subsystems will be used. Whilst at the hardware level this is technical feasible, the more pressing problem is how such memory is presented to the programmer and how its local access is policed. In this paper we illustrate how Java augmented by the Real-time Specification for Java can be used to present the ion of a thread-local scoped memory area. We show how to enforce access to the memory area to a single realtime thread. We implement the model on the JOP multiprocessor system and report on our experiences.
