Static Data ow and Heterochronous Data ow with Hierarchical FSMs in Ptolemy II
نویسنده
چکیده
*charts is a formalism for combining nite state machines (FSMs) with various concurrent models of computation. In *charts, the emphasis is on separating the FSM semantics from the concurrency model semantics. Instead of de ning concurrency models, *charts shows how to combine hierarchical FSMs with various existing concurrency models. This paper discusses an implementation of a subset of the *charts formalism under Ptolemy II. The particular subset implemented consists of static data ow (SDF) combined with hierarchical FSMs and heterochronous data ow (HDF) combined with hierarchical FSMs.

Simulation and Synthesis of Artiicial Neural Networks Using Dataaow Models in Ptolemy
| Arti cial neural networks (ANNs) are often mixed with digital signal processing (DSP) to form understanding and interpretation systems. These systems are heterogeneous in that they contain a variety of algorithms which may be synthesized onto a variety of software and hardware technologies. Because ANN and DSP subsystems are generally data-driven, their computation and control structure can b...

متن کاملSystems Modeling in Ptolemy
Synchronous Dataflow (SDF) is useful in modeling communications and signal processing systems. We describe a communication actor library based on the SDF semantics in Ptolemy II and show how to use these actors to simulate communication systems. However, many communication and signal processing systems nowadays use adaptive algorithms and control protocols. These sometimes violate SDF principle...
متن کاملUnified specification of control and data flow
Many signal processing systems use event driven mechanisms typically based on nite state machines (FSMs) to control the operation of computationally intensive (data ow) parts. The state machines in turn are often fueled by external inputs as well as by feedback from the signal processing portions of the system. Packet-based transmission systems are a good example for such a close interaction be...
