An implementation of the hardware partition in a software/hardware co-designed Java virtual machine

摘要

This paper presents an implementation of the hardware partition of a co-designed Java virtual machine. More specifically, it briefly introduces the concept of the co-designed Java virtual machine, outlines the partitioning scheme between the software and hardware, illustrates the architecture of the hardware partition, and explains the implementation of the hardware partition itself. Using an FPGA as the hardware target provides great flexibility for different configurations. Several tests of Java bytecodes are applied to evaluate the functionality and performance of various features of the hardware. The experimental results are presented and conclusions are given.
