A Brief Survey on Randomizer Design and Optimization for Efficient Stochastic Computing

Stochastic computing (SC) is a promising computing paradigm for circuit design in the post-Moore era. It encodes data through stochastic bit streams (SBSs) and employs a randomizer to generate them, where the randomizer converts binary-encoded variables into stochastic formats and can optionally provide some SBSs of constant values. Owing to this, the randomizer generally plays a critical role in…
