Efficient ASIC Implementation of Artificial Neural Network with Posit Representation of Floating-Point Numbers

Abstract

This paper presents a low-power ASIC architecture of a feedforward Artificial Neural Network using Posit representation. The ASIC Posit shows 50% improvement over ASIC using IEEE 754 format in terms of Power and Silicon Area and is also 13% faster while achieving the same accuracy. The same design using the FPGA platform consumes more power than the ASIC design. The designs are done using Cadence RTL Encounter with TSMC 180 nm technology node.
