This paper introduces a flexible, stream-oriented dataflow processing model based on the "Communicating Logic (CL)" framework. As the target architecture, we adopt the dual layered "Plastic Cell Architecture (PCA). " Datapath processing functionality is encapsulated in asynchronous hardware objects with variable graining and implemented using look-up tables. Communication (i.e. connectivity and control) between the distributed processing objects is achieved by means of inter-object message passing. The key point of the CL approach is that it offers the merits of scalable performance, low power hardware implementation with the user friendly compilation and linking capabilities unique to software.
