I’d rather have that than an uncalibrated clock. The method of using two clocks with different drift coefficients and using that to find the correct time is quite brilliant; the same method is used in the most accurate forms of radioactive dating. You could design and build a dedicated ASIC to do the same calculation, but then you’d have to get the damn thing fabricated, tested, etc and it would probably save you a few cents per package. Easier and faster to adapt an off-the-shelf part.
Edit: Upon re-reading, they never said there IS a CPU in the clock generator package, just that there’s room for one.
A computer inside the clock generator. I need to lie down.

Note to self: Never, ever, go into hardware unless as an employee.
