Oberseminar Eingebettete Hardware-/Software-Systeme

Im Oberseminar finden Vorträge zu aktuellen Forschungsarbeiten statt. Bei den Forschungsarbeiten kann es sich um Bachelor- oder Masterarbeiten oder angestrebte Promotionen handeln.

Das Oberseminar der Abteilung Eingebettete Hardware-/Software-Systeme findet dienstags ab 14:15 Uhr im Raum F02 (wenn nicht anders angegeben) statt. Der hier zu findende Terminplan wird stetig aktualisiert. Wenn an einem Tag kein Vortrag geplant ist, findet das Oberseminar nicht statt.

Titel:
A Compiler Comparison in the RISC-V Ecosystem

Abstract:
The GNU Compiler Collection (GCC) is the traditional compiler for most embedded systems, since it supports many different instruction set architectures (ISA) in its back-end. GCC has also been the first compiler that supported the RISC-V ISA. Since a while Clang/LLVM has gained more and more interest in the embedded software community. Recently, RISC-V is also supported in the LLVM back-end and maintained in the official LLVM release. In this paper we propose a benchmark environment for the comparison of compilers in the RISC-V ecosystem. We perform a comparison of GCC against LLVM for an embedded software benchmark considering compile time, size of the resulting binary, number of instructions and execution time. The results show that LLVM compiles faster in 88% of the experiments, while GCC and LLVM produce nearly the same binary size in 51% of the experiments. In 37% GCC wins and in 12% LLVM wins. In 94% of the experiments the difference between the resulting binary size in GCC and LLVM is +/- 5%. The execution time analysis shows that in 42% of the experiments GCC and LLVM have nearly the same execution time clock cycles while in 40% GCC wins and in 18% LLVM wins.

Titel:
Prediction of the inference throughput and latency for CNN, running on embedded hardware

Abstract:
After the first very successful wave of cloud-based neural network applications, running on large hardware instances, such as GPU or high performance CPU, there is a growing demand for edge computing solutions. Neural networks here are inferred on local hardware for the sake of energy, latency and/or reliability, thus safety constraints. Recently, a large number of embedded AI accelerators have been introduced such as Intel's low power solution Myriad X or ZF's automotive solution ProAI. In order to simplify the development of embedded AI solutions under throughput and/or latency constraints, a methodology is needed, quickly predicting the realizable timing properties to enable design space exploration and avoiding expensive design iterations. This talk will present the concept and first results of such a prediction methodology.
