Background and activities


I am involved in teaching the following courses:

  • TDT4255 Computer Design
  • TDT01 Architecture of Computing Systems

I also supervise project and master thesis topics within computer architecture and design. Current project and master thesis topics are available at IDIs web pages. I often co-supervise projects and masters with local and national industry partners such as ARM, Nordic Semiconductor and Silicon Labs (formerly Energy Micro).

The topics and reports of my supervised master theses can be found on NTNU Open.


The main goal of my research is to contribute to designing faster and more energy-efficient computers. More specifically, I investigate how computer hardware can specialize to the current application – to improve efficiency – while retaining sufficient generality to be efficient across diverse applications – to enable reuse. I am affiliated with the NTNU's Computer Architecture Lab (CAL) and currently serve as the deputy head of the Computing research group.

I am currently involved in the following research project:

We recently completed the TULIPP Horizon 2020 project. One of the key outcomes of TULIPP was the definition of a reference platform for high-performance low-power embedded image processing. Another key contribution is the STHEM utilities which makes it possible to non-intrusively estabilsh the energy consumption of source code constructs such as procedures and loops [video]. To make full use of STHEM, you need the Lynsyn power measurement unit which can be bought from Sundance.

I currently supervise/mentor the following PhD students and post docs:
