How to avoid denormalized numbers?
The same floating-point AMD X86-64 digital signal processing system mentioned in my previous question has a problem where it sometimes slows down substantially when signals attain values very near (but not exactly) zero.
The problem is that…

Are there now 64-bit processors that deal with denorms routinely with no exception or interrupt?
Title says it all.
Are there processors with FPUs that deal with denorms arithmetically correctly (don't assume they're zero nor flush them to zero) and don't cause an exception? I would be interested in knowing who the black sheep and the white…

Is multiplying by Ts faster than dividing by fs?
Say fs = 1000 and Ts = 0.001. Would it be faster to compute Ts at the beginning and subsequently multiply by 0.001 instead of dividing by 1000 when computing frequency-dependent quantities?

Basic question on numerical precision
I appreciate this opportunity to submit a query on this forum.
When studying the continuous-time & discrete-time distinction, specifically with reference to discrete signals being identical when separated by 2*pi, it has struck me that a basic…
