Abstract:  

Modern multimedia devices have to operate in an increasingly dynamic
environment. The availability of processing, storage, and communication 
resources may change over time, resource requirements of an application 
may vary depending on the input data, and quality requirements may 
change depending on the needs and preferences of a user. The question 
arises how to guarantee a reliable operation of a multimedia device in 
these dynamic circumstances.  

The dataflow model of computation for data processing applications 
provides an interesting compromise between 
expressiveness and analyzability. In this presentation, we cover 
various throughput and buffer analysis techniques for dataflow graphs. 
We briefly explore how these techniques can be used in a compilation 
flow for Chip MultiProcessors (CMPs) that is able to cope with the 
increasingly dynamic nature of modern multimedia systems.  

We furthermore outline a run-time adaptation solution for CMPs, that 
forms a basis for the reliable dynamic reconfiguration of the system. 
The solution is parameterized and compositional. The parametrization 
allows a trade-off between the quality of the result and the required 
computational resources. Compositionality ensures scalability of the 
solutions.   

The combination of the compilation and run-time adaptation techniques 
provides the basis for a model-driven fully predictable design 
trajectory for embedded multimedia systems.   

Biography:   

Prof.dr.ir. Twan Basten (1969) is a professor of computational models 
in the Department of Electrical Engineering at the Eindhoven University 
of Technology (TU/e) and a research fellow at the Embedded Systems 
Institute, both located in Eindhoven, the Netherlands. He received his 
MSc and PhD degrees in Computing Science from the Eindhoven University 
of Technology in 1993 and 1998, respectively. Twan Basten worked as 
assistant and associate professor in Computer Science and Electrical 
Engineering at the TU/e, and as visiting researcher at the University 
of Waterloo, Ontario, Canada (1992-1993), Philips Research Laboratories 
(2000-2001) and Carnegie Mellon University, Pittsburgh, PA (2006). His 
research interest is the design of resource-constrained embedded 
systems, based on a solid mathematical foundation, with a special focus 
on networked and multiprocessor systems and computational models. Twan 
Basten is and has been involved in several national and international 
research projects, also as a project leader. He has served (or is 
serving) in over 40 technical program committees. He was the Ambient 
Intelligence co-chair in the DATE 2003 TPC, topic chair in the DATE 
2004 and 2005 TPCs, the TPC co-chair for ACSD 2007, and TPC chair of 
MoCC 2008. He (co)authored over 100 scientific publications, of which 
three received a best paper award, and he (co)supervised 7 PhD degrees. 
He is a senior member of the IEEE and a life member of the ACM.
