This paper proposes a learning scheme for pulse coupled oscillators using the simultaneous perturbation optimization method. Moreover, hardware implementation of the pulse coupled oscillator with learning capability using field programmable gate array is described. It is complicated for ordinary method to find proper parameter values in the pulse coupled oscillator for a proper period, since the pulse coupled oscillator is a kind of recurrent network. The simultaneous perturbation optimization method can give a simple solution to this problem. In addition, this scheme is suitable for hardware realization. Some simulation results of the learning method for pulse coupled oscillators are shown. At the same time, we fabricated FPGA pulse coupled oscillator system with learning mechanism. Results by the hardware system are also shown.
