AMMX in integer form was cheap to implement, however.

When FPU support is added in the future to Vampire boards, I believe we also get these SSE-instructions, but it will take some time. This is off-topic anyway.
For video decoding what we need is a GPU. Then instead of obsolete MPEG-1 this would bring H.264 to the party. No need for MMX or SSE.

Why not ? It would then end up in a flame war and ultimately get closed by the moderation --> problem solved
