Abstract: In one example, an integrated circuit includes a first circuit, a second circuit, a third circuit, and a fourth circuit. The first circuit is configured to receive an input value and generate a first intermediate value based on a first probability density distribution associated with the input value. The second circuit comprises a set of multiplexer circuits configured to select, from a first set of candidate values and based on the first intermediate value, a first product of the first intermediate value and a weight value. The third circuit is configured to generate a second intermediate value based on a sum of the first product and a second product received from another circuit. The fourth circuit is configured to generate an output value based on the second intermediate value and a second probability density distribution associated with the second intermediate value.
