Ptolemy is a third-generation software environment that started in January of It is an outgrowth of two previous generations of design environments.

Optimized software synthesis for DSP using randomization techniques.

For a synthesis-oriented application, it can synthesize assembly code for a programmable DSP, invoke the assembler, and run a simulation.

Automated parallelization, optimisation and mapping to a manycore pro- cessor benefits from the use of a concurrent programming model as the start- ing point.

The Ptolemy part of the RASSP project was to research system-level design methodology for embedded signal processors.

Revised May 10, 1993. Software Synthesis for DSP Using Ptolemy José Luis Pino, Soonhoi Ha, Edward A. Lee, and Joseph T. Buck Department of Electrical Engineering and Computer Sciences University of California Berkeley, CA 94720 Abstract Ptolemy is an environment for simulation, prototyping, and software synthesis for heterogeneous systems.

It uses modern object-oriented software technology (in C++) to model each subsystem in a natural and efficient manner, and to integrate these subsystems into a whole. The objectives of Ptolemy encompass practically all aspects of designing signal processing and communications systems, ranging from algorithms and communication strategies, through simulation, hardware and software design, parallel computing, and generation of real-time prototypes.

In this paper we will introduce the softwa
