INNOVATIONSGESELLSCHAFT TECHNISCHE UNIVERSITÄT BRAUNSCHWEIG MBH

(iTUBS)

Company Description

iTUBS is a spin-off off the Technical University of Braunschweig and strongly connected with it. The TU Braunschweig still holds 40% of the shares of iTUBS the other 60% are held by the local University Association (Braunschweigischer Hochschulbund). The main purpose of iTUBS is to establish industry contacts for the TU Braunschweig and help transferring knowledge and technology between industry and scientific institutes. Thus, Institutes of the TU Braunschweig are able to offer their resources to industrial partners.
TU Braunschweig is the oldest institute of technology in Germany: the cornerstone of this modern university was already laid in the year 1745 with the Collegium Carolinum. The computer science at TUBS has a long tradition. As one of the first universities in Germany, TUBS set up computer science courses as early as in 1972.
Its classic main areas are theoretical, practical, technical and applied computer science. In addition, the study of computer science at TUBS offers a wide range of modern applications-oriented sub-areas of computer science, which extends from the computer graphics on embedded systems and computer science to medicine to robotics and ubiquitous computing (ubiquitous information technology).
The Chair of Chip Design for Embedded Systems at TUBS (iTUBS), led by Prof. Dr.-Ing. Mladen Berekovic, has vast experience in embedded multi-core systems design, processor architecture and reconfigurable processors for DSP applications (Video, Wireless, Security), low-power architectures, mobile robotics and reliable multi-processor systems design. A special focus is placed on advanced hardware accelerator design and software mapping techniques for multi-processor systems.

Role in the project

iTUBS will be the coordinator of the project and lead as such WP6 Project Management. Furthermore, iTUBS will be responsible for WP1 and WP3. iTUBS will contribute to WP2, WP4 and WP5. In WP1 iTUBS will provide programming, algorithm optimization/parallelization expertise. They will also define the system’s software architecture and will contribute to the definition of the system’s hardware architecture and review how it affects programming applications. In WP2, iTUBS will provide inputs and feedback to the mission analysis and results of benchmark activities and propose modifications to applications and algorithms in order to achieve higher performance. In WP3, they will take part in the specification of the system software architecture and provide feedback for the hardware architecture regarding parallel programming support and scalability; they will also contribute to the adoption of a real-time operating system to the management cores and support the integration of RTL functions for processor management tasks. They will also contribute to the definition of the benchmarking methodology and test plans. They will implement the assigned subset of use cases into the software, parallelize and optimize the software, and perform the performance benchmarks. In WP4, iTUBS will examine middleware functionalities and data distribution strategies for space applications. They will include an analysis of space protocols e.g CFDP for integration into the S3NET communication simulation system.
