Communicating logic: an alternative embedded stream processing paradigm

This paper introduces a new concurrent processing model called "Communicating Logic" (CL). As the target architecture we adopt the dual layered "Plastic Cell Architecture" (PCA). Data-path-oriented 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, high performance hardware implementation with the compilation and linking capabilities unique to software.
