Summer School on Models for Embedded Signal Processing Systems
Scientific background and motivation.
In the past two decades, a new programming style has emerged for the concurrent specification and parallel implementation of streaming applications. This so-called visual programming language provides consistent specifications in terms of dataflow models of computation. The objective of the summer school was to offer graduate students, early
stage researchers, and practitioners in signal processing and embedded signal processing systems related domains state-of-the-art model based approaches to specifying concurrent signal processing applications and parallel implementing of these applications.
The summer school was partly devoted to the theory of dataflow models of computation, among which are the dataflow graphs, the dataflow process networks, the Kahn process networks, the reactive process networks, and mixtures of dataflow networks and fine-state machines. This theory was presented in a series of in-depth lectures given by 7 experts in the field. All lectures were based on related chapters, written by the same experts, in a Springer Signal Processing Systems Handbook that appeared precisely in the week that the summer school was held.
Apart from attending the lectures, attendees were actively involved in a series of hands-on sessions in which several specification and design frameworks that have been developed in the research groups of the lecturers were used by the attendees under the supervision of framework developers.
Finally, the program also offered a few regular talks about the usefulness of the theory under practical conditions and constraints, and a really impressive key note by an expert in wireless communication applications.
All lectures have been given in a common style that helped stimulate lively in-class brain storm sessions in which participants spontaneously addressed research issues hidden in or suggested by the presented basics. The gap between the theory lectures and the hands-on sessions was smoothened by a few real life application talks - given by expert practitioners - to illustrate ways in which theory could be successfully turned into useful and powerful specification and design methods. The hands-on sessions were attended by nearly all participants. All of them agreed that the hands-on sessions had been of great value to them.
The organizers of the summer school want to thank the Lorentz Center for offering the opportunity to host it only two months before the event had to take place. The help and guidance of in particular Mieke Schutte (Executive Manager) and Corrie Kuster (Workshop Coordinator) has been excellent and highly appreciated.
Financial support was also mainly provided by the center. Other financial support was received from the ArtistDesign European Network of Excellence, from the HiPEAC European Network of Excellence, and from the IEEE Signal Processing Society.
Organizers, lecturers, speakers, instructors, and participants alike (35 in total) do confirm that the summer school format, style, and content has been a success. Because there is always room for improvement, the suggestion is to do precisely this next year.
