About the Event

Compositional methods, that allow to assemble smaller components into larger systems both efficiently and correctly, are not simply a desirable feature in system design: they are a must for designing large and complex systems. In this talk I will present some recent work on this general theme in the context of embedded systems. A key notion is that of "interface" which allows to abstract a component, hiding details while exposing relevant information. I will present methods for automatic bottom-up synthesis of interfaces for hierarchical synchronous and dataflow models. I will also present interface theories for such models. Interface theories can be seen as behavioral type theories. They include the key notion of refinement, which captures substitutability: when can a component be replaced by another one without compromising the properties of the entire system. I will present two such theories: - synchronous relational interfaces, targeted at synchronous systems and functional properties; - actor interfaces, targeted at dataflow models and performance properties such as throughput or latency.

Biography

Stavros Tripakis is an Associate Researcher at UC Berkeley and visiting Aalto University as an Associate Professor during the Fall of 2012. He obtained a PhD degree in Computer Science at the Verimag Laboratory in Grenoble, France, in 1998. He was a postdoc at UC Berkeley from 1999 to 2001, a CNRS Research Scientist at Verimag from 2001 to 2006, and a Research Scientist at Cadence Research Labs in Berkeley from 2006 to 2008. He works in the areas of embedded, real-time and distributed systems, focusing on model-based and component-based design, verification, testing and synthesis. Dr. Tripakis was co-Chair of the 10th ACM & IEEE Conference on Embedded Software (EMSOFT 2010) and is the current Vice-Chair of ACM SIGBED.
