Ptolemy II, Heterogeneous Concurrent Modeling and Design in JAVA
Edward A. Lee, John Davis, Lukito Muliadi, Steve Neuendorffer, Jeff Tsay · Defense Technical Information Center (DTIC) · 2001
The Ptolemy project studied heterogeneous modeling, simulation, and design of concurrent systems. The focus is on embedded systems, particularly those that mix technologies including, for example, analog and digital electronics, hardware and software, and electronics and mechanical devices (including MEMS, microelectromechanical systems). The focus is also on systems that are complex in the sense that they mix widely different operations such as signal processing, feedback control, sequential decision making, and user interfaces.
