  Ptolemy
       
          A flexible foundation for the specification, simulation, and
          rapid prototyping of systems.  It is an {object-oriented}
          framework within which diverse models of computation can
          co-exist and interact.  For example, using Ptolemy a
          {data-flow} system can be easily connected to a hardware
          simulator which in turn may be connected to a discrete-event
          system.  Because of this, Ptolemy can be used to model entire
          systems.  In addition, Ptolemy now has code generation
          capabilities.  From a {flow graph} description, Ptolemy can
          generate both {C} code and {DSP} {assembly code} for rapid
          prototyping.  Note that code generation is not yet complete,
          and is included in the current release for demonstration
          purposes only.
       
          Version 0.4.1 includes a graphical algorithm layout, code
          generator and simulator.  It requires {C++}, {C} and has been
          ported to {Sun-4}, {MIPS}/{Ultrix}; {DSP56001}, {DSP96002}.
          Ptolemy is an active research project.
