Ptolemy
n 1: Alexandrian astronomer (of the 2nd century) who proposed a
geocentric system of astronomy that was undisputed until
the late Renaissance [synonym: {Ptolemy}, {Claudius
Ptolemaeus}]
2: an ancient dynasty of Macedonian kings who ruled Egypt from
323 BC to 30 BC; founded by Ptolemy I and ended with
Cleopatra [synonym: {Ptolemy}, {Ptolemaic dynasty}]

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.
