1. A nonlinear function operation result output apparatus comprising:
a nonlinear behavior unit configured to autonomously change an internal physical quantity according to a predetermined nonlinear characteristic;
an input converting unit configured to convert an input signal into temporal information using a parameter indicating the predetermined nonlinear characteristic;
a controlling unit configured to control the nonlinear behavior unit
to start, after initializing the nonlinear behavior unit, a change in the internal physical quantity of the nonlinear behavior unit when the input signal is inputted to the input converting unit, and
to stop, after an elapse of the temporal information, the change in the internal physical quantity of the nonlinear behavior unit; and
an arithmetic operation result output unit configured to measure and output the internal physical quantity at a time when the change in the internal physical quantity is stopped as an arithmetic operation result of a nonlinear function having the predetermined nonlinear characteristic.
