Research interests

Design of adaptive hardware architectures

The demands laid down microarchitectures are increasing steadily, and much of the technological innovation of recent decades has only been made possible by the progress of the semiconductor industry and the accomplished increases in integrated circuit performance. A further increase of the
performance of integrated circuits is no longer self-evident, because physical limits will be reached soon. New architectures have to be designed in order to meet the increasing demands at this point.

Artificial intelligence in embedded systems

The performance of embedded systems can be increased enormously by integrating AI algorithms that are adapted to the embedded hardware. Through a hardware/software co-design, a fast and efficient AI execution on embedded systems can be realized. For the development of new cyber-physical systems (CPS) and Internet of Things (IoT) products, AI is becoming an increasingly important factor.
