FPGA prototype of the REALJava']Java co-processor

This paper presents the FPGA prototype of the REALJava co-processor. The virtual machine architecture is described along with the modifications required in the FPGA environment. The FPGA prototype is relevant, as it allows a realistic throughput between the CPU and the co-processor and provides the whole system with a more realistic CPU performance in respect to embedded environments. Our co-processor is designed in a highly modular fashion, especially separating the communication from the actual core. This modularity of the design makes the co-processor more reusable and allows system level scalability. This work is a part of a project focusing on design of an advanced Java co-processor for Java intensive SoC applications.
