Abstract
This study proposes an implementation of pulse-coupled phase oscillators over multiple field-programmable-gate-array (FPGA) communication links. Two FPGAs are connected by a gigabit transceiver and a First-In First-Out interface. To verify the effect of communication delay between FPGAs on oscillator synchronization, we implement four oscillators on the multi-FPGA platform. We have successfully observed synchronization over two FPGAs correctly, despite of a 0.1 μs communication delay. The measurement results show that first spike synchronization requires 12.47 μs with a 3.2 Gbps communication throughput.
