This is not to bad of an idea. The signed 16.16*16.16 multiplication with the shift to be able to do it with 32b*32b multiply is actually a 16.8*16.8 as in 12bits in the operands.
So with 16k of tables I can get this multiply down to 132 cycles always.

What's the anti-troll code?
That's your personal code to be able to add comments and messages on the dhs.nu site.
Don't have a code or forgot it? Fix it here.
