Abstract

In this study, we propose a novel stochastic number generator architecture and prove that the resulting circuit can deliver independent stochastic numbers and improve the accuracy of the calculation results obtained using some recent conventional stochastic computing-based arithmetic circuits. This study is motivated by the increasingly important role of stochastic computing in various fields, such as the digital circuit design, where the stochastic number generators are responsible for a significant share of the hardware cost.
