Floating Point Unit, the part of your computer's processor that
handles floating-point mathematics. Integer calculations are done in
the main CPU, but the FPU (which these days is part of the same hunk
of silicon, but used to be a separate purchase) gets all the really
hard work farmed off to it.

Gross oversimplification, but hopefully helpful.
