| Popis: | The operation of an array of coupled oscillators underlying the associative memory function is demonstrated for various interconnection topologies (cross-connect and star-coupled). Three types of nonlinear oscillators (Andronov–Hopf, phase-locked loop, and spin torque) and their synchronization behavior are compared. Frequency-shift keying scheme of encoding input and memorized data is introduced. The speed of synchronization of oscillators and the evolution of the degree of match are studied as a function of device parameters. |
