Outline of Final Research Achievements

In this research, I have developed a pulse-coupled phase oscillator model with complementing firing-period and its CMOS circuit that is robust against variations in between oscillators for VLSI implementation of brain-like intelligent information processing. As a result of verifying a large-scale oscillator network by numerical simulation, it was found that the developed model can eliminate the variation between oscillator units caused by the large-scale integrated circuit. The proposed model/circuit enables the realization of brain-like hardware that executes high-speed and high-efficiency spike-based computation based on the neural network model. By using this proposed model, it is expected that a processor with higher computational efficiency than the current CMOS digital technology will be developed.
