The 7th International Workshop on Java Technologies for Real-time and Embedded Systems - JTRES 2009   23-09-2009 The 7th International Workshop on Java Technologies for Real-time and Embedded Systems - JTRES 2009 Universidad Complutense de Madrid Facultad de Informatica 23-25 September 2009 Madrid, Spain MOTIVATION: Over 90 percent of all microprocessors are now used for real-time and embedded applications, and the behavior of many of these applications is constrained by the physical world. Higher-level programming languages and middleware are needed to robustly and productively design, implement, compose, integrate, validate, and enforce real-time constraints along with conventional functional requirements and reusable components. It is essential that the production of real-time embedded systems can take advantage of languages, tools, and methods that enable higher software productivity. The Java programming language has become an attractive choice because of its safety, productivity, its relatively low maintenance costs, and the availability of well trained developers. Although it features good software engineering characteristics, standard Java is unsuitable for developing real-time embedded systems, mainly due to under-specification of thread scheduling and the presence of garbage collection. These problems are addressed by the Real-Time Specification for Java (RTSJ). The intent of this specification is the development of real-time applications by providing several additions such as extending the Java memory model, providing stronger semantics in thread scheduling.                                                       Link ...
