E-Bunny: A Dynamic Compiler for Embedded Java Virtual Machines

A new acceleration technology for Java embedded virtual machines is presented in this paper. Based on the selective dynamic compilation technique, this technology addresses the J2ME/CLDC (Java 2 Micro Edition for Connected Limited Device Configuration) platform. The primary objective of our work is to come up with an ecient, lightweight and low-footprint accelerated embedded Java Virtual Machine. This is achieved by the means of integrating a selective dynamic compiler that we called E-Bunny into the J2ME/CLDC virtual machine KVM. This paper presents the motivations, the architecture, the design and the implementation issues of E-Bunny and how we addressed them. Experimental results on the performance of our modified KVM demonstrate that we accomplished a speedup of 400% with respect to the Sun’s latest version of KVM. This experimentation was carried on using standard J2ME benchmarks.
