DCAPS-architecture for distributed computer aided prototyping system

This paper describes the architecture for the distributed CAPS system (DCAPS). The system accomplishes distributed software prototyping with legacy module reuse. Prototype System Description Language (PSL), the prototyping language, is used to describe real-time software in the DCAPS system. PSDL specifies not only real-time constraints, but also the connection and interaction among software components. Automatic generation of software wrappers and glue is applied for the normalization of data transfer between legacy systems. Implementation of the DCAPS communication layer is based on the JavaSpaces/sup TM/ library. DCAPS supports collaborative prototype design in a distributed environment.
