Abstract [en]

In the last 15 years we have seen, as a response to power and thermal limits for current chip technologies, an explosion in the use of multiple and even many computer cores on a single chip. But now, to further improve performance and energy efficiency, when there are potentially hundreds of computing cores on a chip, we see a need for a specialization of individual cores and the development of heterogeneous manycore computer architectures.

However, developing such heterogeneous architectures is a significant challenge. Therefore, we propose a design method to generate domain specific manycore architectures based on RISC-V instruction set architecture and automate the main steps of this method with software tools. The design method allows generation of manycore architectures with different configurations including core augmentation through instruction extensions and custom accelerators. The method starts from developing applications in a high-level dataflow language and ends by generating synthesizable Verilog code and cycle accurate emulator for the generated architecture.

We evaluate the design method and the software tools by generating several architectures specialized for two different applications and measure their performance and hardware resource usages. Our results show that the design method can be used to generate specialized manycore architectures targeting applications from different domains. The specialized architectures show at least 3 to 4 times better performance than the general purpose counterparts. In certain cases, replacing general purpose components with specialized components saves hardware resources. Automating the method increases the speed of architecture development and facilitates the design space exploration of manycore architectures.

Abstract [en]

The joint Student Conference in Interaction Technology and Design and Student Conference in Electronics and Mechatronics is the annual grand finale of the courses Current Topic in Interaction Technology and Design and Student Conference in Electronics and Mechatronics at the Department of Applied Physics and Electronics, Umeå  University. The idea and objective of the two courses are to give the students a forum, where they can actively participate in scientific research and development through their own ideas and interests. The course introduces students to independently finding and researching a topic of interest for them, using a foreign language orally and in writing, writing a scientific article, peer-reviewing and presenting their work at a conference. The conference format was chosen to provide a realistic environment for the presentation of the results. The work has been reviewed both by other participant on the course and members of the department. If the reviews are favorable, the paper is accepted as a full paper at the conference and included in the proceedings.

Abstract [en]

The usage of wireless communication technologies in the implementation of in-vehicle sensor networks is becoming more and more interesting for vehicular manufacturers. However, in order to make a decisive step onto the market, questions about the dependability of wireless technologies always have to be taken into consideration. New standards, as e.g. IEEE 802.15.4 TSCH, offer different approaches towards meeting application demands of different application areas, including those of in-vehicle networks (IVNs). As IVNs become more and more frequent in their usage, also the question about interference management between multiple wireless sensor networks (WSNs) becomes more urgent. As the number of studies on how multiple WSNs can interfere with each other is still limited, this paper will point towards possible methods and further research necessary in order to achieve efficient interference management between non-stationary wireless networks.
