  Abstract

Dedicated-purpose embedded Java system usually takes such model that all class files are converted into a single ROM image by the ROMizer in the host computer, and then the Java virtual machine in the embedded system executes the image. Defining the ROM image is a very important issue for embedded system with limited memory resource and low-performance processor since the format directly influences on the memory usage and effectiveness of accessing entries in classes. In this paper we have analyzed the ROMizer and especially the format of the ROM image implemented in the simpleRTJ embedded Java virtual machine. The analysis says that memory space can be saved up to 50% compared to the original class file and access speed exceeds up to six times with the use of the ROMizer. The result of this study will be applied to develop a more efficient ROMizer for a ROM-based embedded Java system.
