Also, i dont quite realize how important floating point ops are in a data-warehousing application. They just pile up tons of (faxes/emails/phone recording).
It has been a while but as I recall Digital Signal Processing is very floating-point intensive. It really is a specialized application so as far as I know whenever posible a DSP is used instead of a general CPU. I seem to recall that DSPs have special shift register capabilities (like 1024 bits) for example. Maybe someone else here can elaborate.
Also search google for info on FFT (Fast Fourier Transform). As I recal the idea is any sound wave can be represented by a sum of different sine waves and a Fourier transform is applied to the input sound to get a set of sine functions which produce the sound. (I think that's what happens but again maybe someone else can explain things a bit more clearly.)
