Real-time Java processor optimized for RTSJ
Zhilei Chai, Wenke Zhao, XU Wen-bo · 2007
Due to the preeminent work of the real-time specification for Java(RTSJ), Java is increasingly expected to become the leading programming language in real-time systems. To provide a Java platform suitable for real-time applications, a real-time Java processor can execute Java bytecode directly is proposed in this paper. This processor provides efficient support in hardware for mechanisms specified in the RTSJ and offers a simpler programming model through ameliorating the scoped memory of the RTSJ. The most important characteristic of the processor is that its WCET(worst case execution time) of the bytecode execution is predictable. It is vital for the real-time systems.
