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.
