AI applications are increasingly penetrating all areas of life, from the smallest systems in the human body for medical diagnosis, through automated driving, up to complex data analysis and language models on high-performance server systems. In contrast to the biological model, the performance of artificial neural networks can so far only be realized with an order of magnitude higher energy demand. Therefore, holistic solutions for energy- and resource-efficient AI are needed to enable its use in a wide range of applications, including the smallest sensor devices. In this talk, a flexible configurable AI accelerator platform is presented that can be adapted to different application domains, such as medical in-body sensors (diagnostic capsules, neuro-implants) and smart automotive sensors, by an automated AI system HW/SW codesign process. Several chips have already been taped out in Globalfoundries' 22FDX technology, operating with a power consumption between 500nW and 10µW while ensuring given real-time constraints.
