Abstract: A stochastic data processing technique in which a conversion signal is generated representing a pseudorandom sequence of numbers. The conversion signal is then used to convert input signals representing a pair of input operands into respective first and second stochastic signals. The same conversion signal is used to encode both operands. A primitive data processing operation is then performed on the first and second stochastic signals to produce an output signal that may be converted back into nonstochastic form. The primitive data processing operations include MAX, MIN, absolute difference, arithmetic mean and multiplication. For multiplication, one of the stochastic signals is subjected to a predetermined delay.

TL;DR: This paper proposes a new approach: splitting clock domains at a very fine level, down to the level of a handful of gates, by adopting the paradigm of stochastic computation, where signal values are encoded as random bit streams.
