Exploiting Uniform Spatial Distribution to Design Efficient Random Number Source for Stochastic Computing

Stochastic computing (SC) generally suffers from long latency. One solution is to apply proper random number sources (RNSs). Nevertheless, current RNS designs either have high hardware cost or low accuracy. To address the issue, motivated by that the uniform spatial distribution generally leads to a high accuracy for an SC circuit, we propose a basic architecture to generate the uniform spatial di…
