| | | | A couple of years ago I described a primep which possesses various properties that renders it useful for computing number-theoretic transforms over the field $latex \mathbb{F}_p$. Specifically, we have: $latex p = \Phi_{192}(2) = \Phi_6(2^{32}) = 2^{64} - 2^{32} + 1$ where the first of these equalities uses the identity that: $latex \Phi_{k}(x) = \Phi_{rad(k)}(x^{k/rad(k)})$... | |

| | | | Sometimes you need more precision than integers can provide, but floating-point computation is not trivial (try reading IEEE 754). You could use a library or IP block, but simple fixed point maths can often get the job done with little effort. Furthermore, most FPGAs have dedicated DSP blocks that make multiplication and addition of integers fast; we can take advantage of that with a fixed-point approach. | |
