High Performance Java Hardware Engine and Software Kernel for Embedded Systems

This paper describes an effective approach to Java execution through the use of embedded processors. A pair of hardware engine and software kernel are devised for existing embedded systems in order to execute Java applications efficiently, in such a way that 39 instructions are added to the original JVM dedicatedly for the software kernel implementation. The whole embedded system including the hardware engine of 6-stage pipeline with 30K gates can be integrated in a single chip. The proposed approach improves the execution speed by a factor of 5.7 in comparison with J2ME software implementation.
