High-Speed Stochastic Circuits Using Synchronous Analog Pulses

The primary advantages of stochastic computing are the very simple hardware required to implement complex operations, its ability to gracefully tolerate noise, and the skew tolerance. Its relatively long latency, however, is a potential barrier to widespread use of this paradigm, particularly when high accuracy is required. This work proposes a new, high-speed, yet accurate approach for implementing stochastic circuits that uses synchronized analog pulses as a new way of representing correlated stochastic numbers.
