The collector -observes positive flank events in the input noise signal and measures the -time between these events using a counter. The counter is free running -and increases once for each clock cycle (currently running av 50 MHz). - -The LSB of the counter is added to a 32-bit entropy register at each -event. - -As debug output the entropy register is sampled at a given rate -(currently a few times per second). The debug output is connected to LED -on the FPGA development board. - -The project also contains project files, pin assignments and clock -definition neded to implement the design on a TerasIC DE0-Nano board. |
