- The 0.4 release of Ptolemy is now available.
-
- Ptolemy provides a highly 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, etc. 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.
-
- Ptolemy has been used for a broad range of applications including
- signal processing, telecomunications, parallel processing, wireless
- communications, optical phase lock loops, real time systems, and
- hardware/software co-design. Ptolemy has also been used as a lab
- for signal processing and communications courses. Currently Ptolemy
- has hundreds of users in over 75 sites, both in industry and academia.
-
- Ptolemy is available for the Sun 4 (sparc) and DecStation (MIPS)
- architectures. A port to the HP workstation is in progress.
- Installing the system requires 49 Mbytes for Ptolemy (64 Mbytes
- after you optionally rebuild) and 16 Mbytes for the Gnu tools
- subset. At least 8 Mbytes of physical memory are required.
-
- Ptolemy has been developed at UC Berkeley over the past 3 years.
- Further information, including papers and the complete release
- notes, is available from the FTP site.
-
- A license is no longer required to receive Ptolemy. The source code,
- binaries, and documentation are available by anonymous ftp from
- ptolemy.berkeley.edu
- [ftp "ptolemy.bekeley.edu". login as "anonymous". cd "pub". get README]
