Smartphones, robots, drones, cameras, security cameras - all these devices will need some sort of integrated AI processing, very soon. But if the inference is to take place directly on the imaging device, things are becoming interesting. So what are the challenges and benefits of using AI on an edge device? In this talk, we will discuss hardware options available for implementing AI acceleration on an edge device and how they differ from each other. There are already functioning approaches and solutions. But only a few are sufficiently flexible to keep pace with the rapid progressing development.
