Computer Architecture for Embedded Systems

Welcome to the Computer Architecture for Embedded Systems (CAES) group of the Faculty of Electrical Engineering, Mathematics and Computer Science of the University of Twente in the Netherlands.

Our mission is to perform research and education on energy-efficient and dependable embedded systems.

Best paper award

H.G. Kerkhoff and H. Ebrahimi have won the best paper award for their paper titled "Intermittent Resisitive Faults in Digital CMOS Circuits". The paper is published in IEEE 18th International symposium on design and diagnostics of electronic circuits and systems, held 22-24 April 2015 in Belgrade, Serbia.

CAES PhD Joost Hausmans received his doctorate degree ‘cum laude’

CAES PhD Joost Hausmans received his doctorate degree ‘cum laude’ for his thesis entitled: “Abstractions for Aperiodic Multiprocessor Scheduling of Real-Time Stream Processing Applications”

Real-time stream processing applications often have a dynamic character. Execution times of the tasks and processing rates of the tasks vary and can even be data dependent. The systems on which these applications execute thus have to support this dynamic behavior. The tasks of the stream processing applications are therefore executed data-driven on run-time scheduled resources.

UT researchers test power network with pizza ovens

How much load can the electricity network really take? That was the key question during a special test in Lochem last week, in which researchers from the University of Twente participated. Twenty residents were assigned the task to bake a pizza in their electric oven, while the electric car was charging in the driveway. The network became overloaded after an hour and there was a power outage in part of the network.

The test was intended to imitate the situation in 2025, when the amount of electric cars has substantially increased and the energy demand of households will also have more spikes. It was the first time that the power supply was tested in such a way in the Netherlands. Through the test the researchers were provided with a solid impression of the effects the energy demand of the future has on a power network, and subsequently what is required of intelligent power networks in order to prevent power outages in the future.

Enorme besparing op chipontwerp mogelijk

ICT-onderzoekers van de Universiteit Twente hebben een programmeertaal ontwikkeld waardoor het mogelijk is de enorme kosten van het ontwerpen van hardware beheersbaar te houden. Tijdens het ontwerpproces van nieuwe chips gebruiken fabrikanten al twintig jaar dezelfde technieken. Daarbij moet na elke stap in het ontwerpproces uitvoerig getest worden. Dat kost veel geld. De moderne, zogenaamde functionele programmeertaal maakt het mogelijk vooraf te bewijzen dat ontwerptransformaties honderd procent foutloos zijn.
