Abstract:

While it is common to design hardware (HW) and software (SW) separately and independently in general purpose systems, such a serialized design approach would result in substantial inefficiencies in the design of domain-specific systems; it may lengthen the design time and significantly increase the amount of design efforts when the tradeoffs between the HW and SW could only become clear in the later design stage. HW/SW co-design, as the name implies, refers to design methodologies for electronic systems that exploit the tradeoff, synergy, and interaction of HW and SW in a holistic way from the early design stage. In this talk, I will first brief the audience on the existing design practices for various domain-specific computer systems with exemplar HW/SW platforms. Then, a model-based approach to HW/SW co-design will be introduced together with how they can be applied in various domain-specific systems. In particular, it will be shown how the non-functional design concerns, such as low-power/thermal constraints or reliability/safety requirements, can be mediated with the traditional functional requirements, e.g., real-time schedulability. These design practices will be demonstrated with a number of real-life domain-specific computer system examples, including gaming consoles, drones, wireless sensor networks, and satellite systems.


Bio:

Hoeseok Yang received the B.S. degree in computer science and engineering and the Ph.D. degree in electrical engineering and computer science from Seoul National University, Seoul, South Korea, in 2003 and 2010, respectively. He was a Postdoctoral Researcher with the D-ITET, ETH Zürich, Zürich, Switzerland, from 2010 to 2014. He joined Ajou University, Suwon, South Korea, as an Assistant Professor, in 2014, where he is currently an Associate Professor. His current research interests include HW/SW co-design, reliability- and temperature-aware optimization/analysis of multiprocessor system-on-chip (MPSoC), embedded systems design with non-volatile memories, and deep learning for embedded systems. He has been a Technical Program Committee Member of several conferences or workshops, including the Asia and South Pacific Design Automation Conference (ASP-DAC), the Asia Pacific Conference on Circuits and Systems (APCCAS), the International Conference on Embedded and Ubiquitous Computing (EUC), the International Conference on Embedded Computer Systems: Architectures, Modeling, and Simulation (SAMOS), the Symposium on Embedded Systems for Real-Time Multimedia (ESTIMedia), and the International Workshop on Rapid System Prototyping (RSP). He was a recipient of the Best Paper Award at the International Conference on Compilers, Architectures, and Synthesis of Embedded Systems (CASES), in 2012.
