| Research Abstract |
Circuits for a hardware neural computation were fabricated by using single flux-quantum circuits based on stochastic logic. In the stochastic logic, the data is represented by a random pulse generation rate for a certain period on time domain. Main components of this neuron circuit are a multiplication of synaptic weight, a generation of membrane potential, and an activation function. These basic elements of the neuron circuit were fabricated. Some main circuits were successfully demonstrated.
