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.
