A Generic Circuit Platform of Covering All Rational Numbers for Determnistic Stochastic Computing in the Time Dimension

The key advantages of stochastic computing (SC) are its simple arithmetic circuits and high tolerance for bit errors. Deterministic SC (DSC) improves SC by using deterministic bitstreams, resulting in accurate results without fluctuation. Recently, a platform that conducts DSC in the time domain has been proposed. This platform enhances the feasibility of DSC and brings it closer to becoming a mainstream computational paradigm. However, its circuit is unable to represent all rational numbers. This work improves the platform by enabling the representation of all rational numbers for computation. Furthermore, it reduces hardware costs and power consumption, paving the way for new SC applications.
