A study on Java Virtual Machine for Real-time embedded systems

摘要

Real-Time Specification for Java (RTSJ) is intended for Real-time embedded applications. It is believed to be a big invention, a new generation for Real-time applications. However, can RTSJ make a breakthrough in Real-time devices like Java has done for desktop applications? This question is not yet answered. In this study, we present the architecture of a typical JVM, from the first generation, Interpreter architecture, to newest architecture, Just in time with Hotspot mechanism. Also, the structure of RTSJ can affect to the JVM for embedded devices have been analyzed.
