Abstract

This paper gives an overview of coupled oscillators and how such oscillators can be efficiently used to perform computations that are unsuitable or inefficient in von-Neumann computing models. The unconventional computing ability of coupled oscillatory system is demonstrated through Spin Torque Nano Oscillators (STNOs). Recent experiments on STNOs have demonstrated their frequency of oscillation in few tens of gigahertz range, operating at low input currents. These attractive features and the ability to obtain frequency locking using a variety of techniques, make STNOs an attractive candidate for non-Boolean computing. We discuss coupled STNO systems for applications such as edge detection of an image, associative computing, determination of L2 norm for distance calculation, and pattern recognition.
