  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.
