>Could you provide links to the papers, algorithms and design source code ?
The design source code isn't available. There's a lot more to designing chip RTL at 22nm than just the implementation of the algorithms, so I'm not at liberty to reveal the source code.
I'm working towards making some C code available that models the design. This served as part of the design validation (it helps show model equivalence and calibrate entropy estimates) but could also answer a lot of the detail questions people have about the nature of the raw entropy.
