Abstract

Currently, the Real-Time Specification for Java (RTSJ) is silent on multiprocessor issues It attempts not to preclude multiprocessor implementations but provides no direct support. This paper discusses the issues that need to be addressed if the RTSJ is to be better defined for execution on a multiprocessor system. It proposes new dispatching and allocation models. Issues of cost enforcement, interrupts affinity and processor failure are covered.
