Description
Summary:Inaccuracy of computations is an important challenge with Stochastic Computing (SC). Deterministic approaches are proposed to produce completely accurate results with SC circuits. Current deterministic methods need a large number of clock cycles to produce exact result. This directly translates to a very high energy consumption. We propose a method based on the Residue Number Systems (RNS) to mitigate the high processing time of the deterministic methods. Compared to the state-of-the-art deterministic methods of SC, our approach delivers 760x and 170x improvement in terms of processing time and energy consumption.
