Probabilistic arithmetic and energy efficient embedded signal processing [PDF]

open access: yesProceedings of the 2006 international conference on Compilers, architecture and synthesis for embedded systems, 2006
Probabilistic arithmetic, where the ith output bit of addition and multiplication is correct with a probability pi , is shown to be a vehicle for realizing extremely energy-efficient, embedded computing. Specifically, probabilistic adders and multipliers, realized using elements such as gates that are in turn probabilistic, are shown to form a natural ...
