Low-Precision-EMACs

RTL design of posit, fixed-point, and floating point low-precision exact-multiply-and-accumulate (EMAC) units for deep neural networks (DNNs). These designs compute the underlying operation in all DNNs while preserving as much accuracy locally as possible by incorporating the Kulisch exact-dot-product.
