It would seem to be an excellent idea indeed to incorporate a register
which gets filled with fresh entropy (from amplified circuit noise,
for instance) at every clock tick into the CPU directly, particularly
if it is to be used for embedded crypto gadgets.

Of course one would have to believe the CPU designer that it is true
noise, and not pseudorandom.
