Field-Programmable Gate Arrays (FPGAs) are changing the deep learning and AI landscape. FPGAs have emerged as a potent alternative to traditional processing units, for organizations looking at more flexible and efficient approaches to AI implementations. And that brings us to this guide, which attempts to cover all you need to know about using FPGAs for deep learning applications.
