Embedded Java on ARMlinux

Abstract

Java technology for the embedded system is widely developed as the results of increasing of usage of the embedded system. The characteristics of Java, such as threading support, portability, and independence of platform, can enhance the performance of the embedded system. However, currently, there is no Java platform or Java environment which is able to support every embedded platform yet. Moreover, for some embedded platforms which have small memory space, it is impossible to implement full range of Java Environment and applications since Java has a large size of the class library. The objective of this project is to implement an open source Java Virtual Machine to enhance the performance of the embedded platform by using the ARM-based processor with Linux Operating System Embedded Platform from SIMTech as the target platform for this project. In this project, the selected Java Virtual Machines from the selection process are implemented and tested by running the provided Java applications. As the results, Java Virtual Machines with necessary environment are available for running Java applications on the target platform. Guidelines of implementation and troubleshooting the selected Java Virtual Machines are provided. Furthermore, the limitations, the embedded platform’s performance and the suggestions of further works are also discussed.
