Abstract

This study proposes High-Speed Synchronization of Pulse-Coupled Phase Oscillators on multiple field-programmable-gate-array (FPGA). Winfree model is used for oscillators communication based and two FPGAs are connected by a gigabit transceiver (GTX). In order to verify the effect of communication delay and in-phase synchronization phenomenon between FPGAs, we implement various number of oscillators on the multi-FPGA platform. Four-oscillator network achieved first spike synchronization over two FPGAs within 12.47 \(\upmu \)s and datastream bitrate up tp 3.2 Gbps. We have successfully expanded the network from the previous study and verified that the 10 \(\times \) 10 pulse-coupled phase oscillators synchronized over two FPGAs via high-speed serial communication with a 0.1 \(\upmu \)s delay and the network reached a steady synchronization state after the spike-count reached 100 with a maximum frequency 298.014 MHz.
