IA32 MMX does provide saturated arithmetic. All that are in Intel
documentation. I mentioned about that some time  ago in
discussion regarding direct support of MMX extensions by
Ada compileres.

But even without that it is  very easy to write a piece of external
assembler code that uses MMX and import it in Ada spec file.
