NEW: As of April 1, 2024 I have become Professor emeritus.
The department is hosting a farewell reception on May 16, 2024, 15:30 - 17:30. See invitation
This is my personal web-page.
I also have an official DTU web-page

Research Interests

Digital systems. Asynchronous circuits. Low-power design. Networks-on-Chip. Many-core architecture. Cyber physical systems.


An up-to-date publication is found on my official DTU web-page
I also have a profile in Google Scholar

I have co-authored what has become the standard textbook on asynchronous circuit design:

Jens Sparsø and Steve Furber (eds.),
Principles of asynchronous circuit design - A systems perspective.
Kluwer Academic Publishers, 2001.

In 2009 the book was translated into Chinese at the initiative of the Chinese Academy of Sciences.

As of 2006, Part I of the book, i.e.:
Jens Sparsø, Asynchronous circuit design - a tutorial, chapters 1-8,
is freely available for non-commercial educational use. [Go to download]

June 2020: NEW BOOK

Jens Sparsø,
Introduction to Asynchronous Circuit Design
DTU Compute, Technical University of Denmark
2020. (273 pages)

This is an updated and extended version of my tutorial on asynchronous circuit design.
The extensions include:
(i) improved coverage of data-flow components
(ii) a new chapter on two-phase bundled-data circuits
(iii) a new chapter on metastability, arbitration, and synchronization
(iv) a new chapter on performance analysis using timed Petri nets

With these extensions, the text provides more complete coverage of the field and it is now made available as a stand-alone book.
The book is available in two formats:

Jens Sparsø (Member, IEEE) is a professor at the Technical University of Denmark (DTU). His research interests include: design of digital circuits and systems, design of asynchronous circuits, low-power design techniques, application-specific computing structures, computer organization, multi-core processors, and networks-on-chips - in short, hardware platforms for embedded and cyberphysical systems.
He has published more than 100 refereed journal and conference papers and is co-author of the book ``Principles of Asynchronous Circuit Design - A Systems Perspective'' (Kluwer, 2001), which has become the standard textbook on the topic. He received the Radio-Parts Award and the Reinholdt W. Jorck Award in 1992 and 2003 respectively, in recognition of his research on integrated circuits and systems. He received the best paper award at ASYNC 2005, and one of his papers was selected as one of the 30 most influential papers of 10 years of the DATE conference.
He has supervised 17 PhD students. Two are underway and 15 have successfully completed their studies. Among the latter, two are now in academic careers, and the rest have established successful careers in research and development in national and international companies.
He is a member of the steering committee the ACM/IEEE Intl. Symposium on Networks-on-Chip (NOCS).


Currently (2019-20) I teach the following courses: In the past I have developed and taught a range of different courses on:
