Systems Research and Architecture Group (SRA)
Our Research and Teaching activities are centered around the architecture of computing systems: From hardware over system software up to languages and compilers with a focus on constructive methods for the design and development of adaptable and versatile system software. The group is led by Prof. Daniel Lohmann.
EmbeddedThose machines that are closest to our everyday life are special-purpose systems embedded into the physical world. Due to this embedding, we know a lot about the surroundings of a system. We exploit this knowledge in the design of hardware and system software.
TailoredThe requirements for every system are special. However, we often favor unspecific general-purpose components over special-purpose solutions. With the techniques of automatic tailoring, we can achieve specialized systems at moderate development costs.
SystemsDuring the architectural design, the required functionalities are often well understood. Nonfunctional aspects are decisive for choosing a system for a given task. Especially for embedded systems, we can optimize various aspects towards the given application scenario.

Mit Unterstützung der Kollegen vom IKT findet das erste Gesamttreffen des neu gegründeten Fachbereich SYS der Gesellschaft für Informatik (GI) am 1. und 2. März 2018 hier in Hannover statt. Mit mehr als zwölf Beiträgen aus dem Bereich der Betriebssysteme, Kommunikationssysteme und Verteilten Systeme erwartet die 70 angmeldeten Teilnehmer ein spannendes Programm.
- AHA: Automated Hardware Abstraction in Operating-System Engineering (DFG: LO 1719/4-1)
- Goal of AHA is to improve nonfunctional properties of system software by a very deep, but fully automated specialization of the application-hardware bridge represented by the operating system. We investigate, how alternative implementations that are mapped more directly to hardware features, can be generated from a concrete application and their actual interactions with the operating system.
