We believe in a tiled heterogeneous architecture, with tiles having a varying degree of flexibility in order to achieve energy-efficient systems. We envision that the multi-processor system-on-chip (MPSoC) can be extended to multiple chips on a board (MCoB) and multiple boards in a system (MBiS). We advocate the use of network-on-chip (NoC) with varying degrees of sophistication. Furthermore, we stress the use of smart adaptive systems which are environment aware and can adjust in order to save energy, become more robust against faults or reduce interference with other systems.

The correctness of a system not only depends on the correctness of the design but also on the correct functioning of the underlying hardware and the correct behavior of the environment including the user. This includes not only accidental failures of system components or the environment, but also active attacks by both insiders and outsiders. Such a dependable (or trustworthy) system must be both fault tolerant and secure. The attributes of dependability are:

The central theme of our research on fault-tolerant computing and dependability is the development of a fundamental approach to the design of dependable digital systems with main emphasis on:

Research topics in this area include: adaptive systems, fault tolerance, dependable design and distributed systems.

CRISP: Cutting edge Reconfigurable ICs for Stream Processing

The CRISP project is a EU co-funded project, in which a single highly scalable reconfigurable system concept is developed that can be used for a wide range of streaming applications; from low-cost consumer applications to very demanding specialty applications. The project is performed by an adept consortium consisting of Recore Systems, University of Twente, Atmel Germany, Thales Netherlands, Tampere University of Technology and NXP Semiconductors. CRISP is acronym for Cutting edge Reconfigurable IC's for Stream Processing.
