PROBABILISTIC CALCULATION ELEMENT, DRIVE METHOD THEREOF, AND RECOGNITION DEVICE USING THE SAME

摘要

A probabilistic calculation element includes a fluctuation generation device (15) for outputting an analog amount having fluctuation, fluctuation difference calculation means (401) for outputting fluctuation difference data obtained by adding the output from the fluctuation generation device to an analog difference between two data, a threshold value processing device (47) for outputting a pulse by performing threshold value processing of the output from the fluctuation difference calculation means, and pulse detection means for detecting a pulse output from the threshold value processing device.
