Communication scheme for an advanced java co-processor

This paper describes interface strategies for a Java co-processor (from now on JPU). The interface units are inter?? changeable, and share a common communication scheme towards the co-processor. The rst version of the interface is designed for single CPU and single co-processor environment. The other is for a network of multiple CPUs and co?? processors. The co-processor does not need to know what kind of environment is is placed in, as all communication goes through the interface unit. This modularity of the de?? sign makes the co-processor more reusable and allows sys?? tem level scalability. This work is a part of a project focusing on design of an advanced Java co-processor for Java intensive SoC applications.
