Heterogeneous Concurrent Modeling and Design in Java (Volume 2: Ptolemy II Software Architecture)
Abstract
This volume describes the software architecture of Ptolemy II. The first chapter covers the kernel package, which provides a set of Java classes supporting clustered graph topologies for models. Cluster graphs provide a very general abstract syntax for component-based modeling, without assuming or imposing any semantics on the models. The actor package begins to add semantics by providing basic infrastructure for data transport between components. The data package provides classes to encapsulate the data that is transported. It also provides an extensible type system and an interpreted expression language. The graph package provides graph-theoretic algorithms that are used in the type system and by schedulers in the individual domains. The model transformation package provides a mechanism to systematically transform models by means of graph rewriting. The plot package provides a visual data plotting utility that is used in many of the applets and applications. The codegen package is a templated based code generator similar to the Ptolemy Classic code generators. The copernicus package is a code generator that performs static analysis on Java class files to produce smaller, faster executable models. Volume 1 gives an introduction to Ptolemy II, including tutorials on the use of the software, and volume 3 describes the domains, each of which implements a model of computation.
