raw samples at 1.6Gb/s would be useful infrequently[0]; raw samples
from a trusted device extremely useful at any bitrate!

what is "my chip" and how can we find out more / support your efforts?


best regards,


0. to date i have only maxed out 400Mb/s raw VIA Padlock sources for
SSD FDE initialization and constructed experiments in temporal key
rolling.  it is however common to regularly consume on the order of
10Mb/s on a busy server, generating many keys, using crypto happy
software, etc.  (this is why every processor, every embedded device
should have a physical entropy source, with access to raw samples.
still waiting...)
