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.
