PD Symposium 2024

Our PD-Symposium-2024 was held in the beautiful city of Prague. During the workshop, we shared diverse ideas in the domains of machine learning, approximate computing, security & emerging reconfigurable technologies. Moreover, we enjoyed three interesting talks on the topics of Edge AI, Neuromorphic Computing, and in Wafer-Scale AI Chips, presented by Prof. Huang Kejie, Prof. Ma De, and Prof. Zhu Xiaolei from Zhejiang University (China). Through fruitful brainstorming sessions and team-building exercises, the symposium facilitated strategic planning for the future.

Kudos to Cecilia and thanks to the committee members: Prof. Diana Goehringer, Prof. Jeronimo Castrillon, Prof. Horst Schirmeier and Prof. Lukas Sekanina.

PD Group Day 2023

Our adventurous group day this year had quite Adrenaline! Klettering among the trees at the 10 meter height surely is one of a kind challenge. Have you ever tried balancing yourself on squeaky swings and hanging bridges? Shaking feet, sweating out of stress after 5 hours! Challenging, right? Well that is how we like it at PD Group, facing new challenges 😎
(The bruises and spasm came afterwards though 😅). Maybe next year we head for Bungee-Jumping 😜

PhD defense of Mehdi Moghaddamfar

We celebrate the Ph.D. defense of Mehdi Moghaddamfar (co-supervised with Prof. Wolfgang Lehner, Database group - TU‌ Dresden), for successfully defending his thesis on 'Database System Acceleration on FPGAs'. Kudos to Mehdi, Prof. Lehner, and his industry supervisors, Dr. Christian Färber (INTEL cooperation) and Dr. Norman May and Arne Schwarz (SAP SE).

PD Symposium 2023

We held the PD chair Symposium this year, in a nice hotel and environment in Altenberg. Team-members have shared their recent researches and provided/received feedback from each other in different perspectives: from logic-synthesis (transistor-level) to implementation (architecture-level) and security, reliability, and accuracy (application-level). It was a two-day energetic and fruitful brainstorming, for all of us 😊

Two PhD Defenses in One Day!

Congratulations to Michael Raitza and Behnaz Ranjbar for successfully defending their PhDs. Michael's theis was on 'Analytical Exploration and Quantification of Nanowire-based Reconfigurable Digital Circuits' which was a result of our continued collaboration with NaMLab. Behnaz's thesis was on 'Quality-of-Service Aware Design and Management of Embedded Mixed-Criticality Systems', in collaboration with Sharif University of Technology. Thanks to all the committee members: Jeronimo Castrillon, Thomas Mikolajick, Diana Goehringer, Aviral Shrivastava, Hussam Amrouch, and Alireza Ejlali. We are happy that Michael and Behnaz will continue their work in PD‌ chair as Post-Docs.


PD Group Day 2022

Our adventurous group day this year had many ups and downs! Jugging in the scenic nature of Stadt Wehlen, then hiking up to Bastei Bridge, and finally taking down hundreds of stairs to reach the beautiful Amselsee and Amselfall (Amselfall was 'under construction' 😄). Nevertheless, we again enjoyed our annual boat-rowing which already has become a ceremony, but this year in a peaceful lake without mosquitos 😊 It was a memorable day, especially für unsere fußbeine, after hundreds of stairs 😄

PhD defense of Shubham Rai

We are proud to share that Shubham Rai successfully defended his thesis on 'Design Automation and Application for Emerging Reconfigurable Nanotechnologies'.‌ Shubham has been a supportive teammate and helped the reasearchers in his team. We also thank Prof. Giovanni De Micheli, Prof. Thomas Mikolajick, Prof. Walter Weber, and Prof. Diana Goehringer for being a part of the committee. We wish Shubham all the bests and happy that he will continue his work with PD‌ chair as a Post-Doc.

PD Chair at ICCAD 2021

The team of PD Chair presented three work at ICCAD-21, one of the top venues in hardware/software design. The joint projects are accomplished in collaboration with Infineon, IFTE, and Indian Institute of Technology Indore. Shubham Rai, Elias Trommer, and Dr. Andreas Krinke presented "dCSR: A Memory-Efficient Sparse Matrix Representation for Parallel Neural Network Inference", "RL-Guided Runtime-Constrained Heuristic Exploration for Logic Synthesis", and "Exploring Physical Synthesis for Circuits based on Emerging Reconfigurable Nanotechnologies" respectively . You will see more at our YouTube channel.

PD chair won second-place award in IMAGING SCIENCE Contest

As well-said by Joseph Beuys “Every human being is an artist, a freedom being, called to participate in transforming and reshaping the conditions, thinking and structures that shape and inform our lives.”

To share "Die Schönheit der Wissenschaft" with people worldwide, Cfaed annually opens up a gallery with a selection of amazing illustrations, achieved by TUD researchers. The origins of these artistic visualizations are extremely diverse, from amazing behaviors observed under ultra-strong electron microscopes to deliberately-created graphics to depict scientific relationships of research results. The 5th exhibition this year was held in Altana Gallery of TU Dresden, in 17th September.

Chair of Processor design also joined this call and is honored that we can share the beauty of our research with the world through three images in the area of Approximate Computing used in Machine Learning (Zahra and Salim) and Silicon Nanowire FET transistors (Shubham). Zahra won second-place award out of more than 300 great submitted works and represented our illustrations to the rector of TU Dresden, Prof. Ursula Staudinger and many scientific visitors from different institutions. You can see a preview of her presentation on Cfaed's Youtube channel.

PD Chair in Spreewald

For group day we decided to mix both, relaxing in nature & experience adventure. After hiking in the beautiful routes of Lübbenau, our sportive & creative team decided not only to explore but also to open up new tracks of rowing in Spreewald Fließen (last pic)! It was an energetic and memorable day which brought much more, z.B. joy of itching due to mosquitos!
