I went to your site and I couldn't find any description on just how
your RNG produces its bits or how they are processed. High-quality
true random number generators are very hard to achieve, especially at
a multi-megabit/sec rate!

How do you determine the actual entropy generation rate? Most designs
simply take a few bits of entropy and stretch them with some type of
deterministic process to produce a high rate of what they call "true"
random bits.
