Nowadays, Approximate Computing (AxC) represents a novel and interesting design paradigm for building modern systems with better trade-off between efficiency, in terms of performance, power consumption, hardware area, execution timing, and the quality of the final outcomes. Indeed, AxC is based on the intuitive observation that, while performing exact computation requires a high amount of computational resources, allowing a selective approximation or an occasional relaxation of the specification may provide significant gains in energy efficiency. Suitable solutions will not be fully realized in a single layer only. Therefore, applying AxC in different layers of hardware, architecture, software and algorithms should be investigated. Moreover, while the hidden cost of AxC is a reduction of an application’s inherent resiliency to errors, AxC has also recently been demonstrated to be effective in safety-critical applications. This workshop (fifth edition after successful ones at Paderborn’15, ESWEEK’16, ETS’18, DATE’19) aims at exploring AxC techniques applied at different layers, such as hardware, architecture, software and algorithms, making room for the exploration of methodologies able to exploit effective and real systems that can inspire application in many recent application domains such as machine learning, safety and security.

Jürgen Teich bio: Teich is with Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU), Germany, where he is directing the Chair for Hardware/Software Co-Design since 2003. He received the M.S. degree (Dipl.-Ing.; with honors) from the University of Kaiserslautern, Germany in 1989 and the Ph.D. degree (Dr.-Ing.; summa cum laude) from the University of Saarland, Saarbrücken, Germany, in 1993. Prof. Teich is involved in many interdisciplinary projects on basic research as well as industrial projects. From 2003- 2009, he was an elected board member (Fachkollegiat) of the Deutsche Forschungsgemeinschaft (DFG) for the area of Computer Architecture and Embedded Systems. He has been the initiator and coordinator of the DFG priority programme 1148 on "Reconfigurable Computing". Since 2010, he has been the principal coordinator of the Transregional Research Center 89 "Invasive Computing" funded by the German Research Foundation (DFG). He is a member of the Academia Europaea, of the National Academy of Science and Engineering (acatech), and a Fellow of the IEEE.
