Accelerating embedded java']java for mobile devices

With the proliferation of wireless devices, networks, and systems, the deployment of efficient embedded Java virtual machines is becoming a challenging and important research area. Accordingly, a plethora of acceleration techniques have been proposed. In this article we present a new acceleration technology that we developed for embedded Java virtual machines. Acceleration is achieved by the integration of a new selective dynamic compiler, which we called Armed E-Bunny, into the J2ME/CLDC (Java 2 Micro-Edition for Connected Limited Device Configuration) Kilobyte Virtual Machine (KVM). The modified KVM is ported on a hand-held PDA that is powered with Embedded Linux. Experimental results demonstrate that we accomplished an important speedup (more than 360 percent) with respect to Sun's latest version of KVM. This experimentation was carried out using standard J2ME benchmarks.
