RNG processing box based on FPGA and Raspberry PI.
This module takes 4 gigabit streams from Random Number Generators, samples it with GTP transceiver and calculates statistics in real time in the FPGA. Calculated statistics are time-tagged with GPS time. Data are then transferred to the RPI which sends them to the central server. RPI is also responsible for FPGA gateware update/configuration. This design is derived from NETV2 project: https://github.com/AlphamaxMedia/netv2-mainboard Parts of schematics and routing were used.
