In this paper, we presents the design of a hardware temporal multi-threading architecture for a Java processor. The Java virtual machine (JVM) model is a stack machine where the process state is the snapshot of the Java stack. If the runtime stack is stored (or cached) in on-chip memory for performance reasons, the backup and restoration of the Java runtime stacks for context switching would be expensive...
Currently multicore systems start to be used even in low-end devices such as embedded systems controllers requiring real-time guarantees. Hardware Transactional Memory (TM) is a new synchronization paradigm for this architecture, allowing problems of lock-based methods and making easer programming. We propose to use TM to synchronize the concurrent/parallel execution of the Garbage Collector (GC)...
Multi-threaded real-time applications run on platforms that offer services such as concurrency, timing and synchronization. In a model driven context, separation of concerns between functional specification and design choices is one of the key challenges. For that purpose, annotations defined by the MARTE sub-profile for software resource modeling (SRM) provide high level abstractions of target software...
