An experimental study of Java objects behaviour for mobile architectures
Abstract
Java is an interesting programming language in the context of embedded applications for the flexibility and security it provides. However, its execution requirements and performances are often an issue. We plan to build a better Java execution environment, targeting mobile phones. To improve its performances, we believe that a special attention has to be put on the mapping of Java objects in memory. To understand the issues, an overview of memory inside a standard Java Virtual Machine is proposed. Then, relevant characteristics and behaviours of objects from selected embedded applications are presented. Their similarities with standard desktop applications are also illustrated, along with a first discussion on how they could be organized on memory.
