Ptolemy Project

The Ptolemy Project is an ongoing project aimed at modeling, simulating, and designing <a href="/facts/Concurrency_(computer_science)/Ctnrrq4A">concurrent</a>, <a href="/facts/Real-time_computing/p9HxgL4L">real-time</a>, <a href="/facts/Embedded_system/a4muX1wU">embedded systems</a>. The focus of the Ptolemy Project is on assembling concurrent components. The principal product of the project is the Ptolemy II <a href="/facts/Model_based_design/6EXz2qjp">model based design</a> and simulation tool. The Ptolemy Project is conducted in the Industrial Cyber-Physical Systems Center (iCyPhy) in the Department of Electrical Engineering and Computer Sciences of the <a href="/facts/University_of_California,_Berkeley/MXVEjklr">University of California at Berkeley</a>, and is directed by Prof. Edward A. Lee.
The key underlying principle in the project is the use of well-defined <a href="/facts/Model_of_computation/nJr8mHSI">models of computation</a> that govern the interaction between components. A major problem area being addressed is the use of heterogeneous mixtures of models of computation.
The project is named after <a href="/facts/Ptolemy/htudGQTQ">Claudius Ptolemaeus</a>, the 2nd century Greek astronomer, mathematician, and geographer.
The Kepler Project, a community-driven collaboration among researchers at three other <a href="/facts/University_of_California/M9AWowUd">University of California</a> campuses has created the <a href="/facts/Kepler_scientific_workflow_system/x2PphRu1">Kepler scientific workflow system</a> which is based on Ptolemy II.
