SSE2 instructions: i need int128

[user]

Hello
Does windows implements any classes for 128 bit integers ?
(implementing SSE2::asm instructions like: movqa and others operation on
D-QW 128 bit integers).

Maybe there is any class/library that was created for cryptology for
operation on very long (big) numbers ?
I found miracl, and it is very fast but unfornatelly it unnececary usues
to much memory for it's big numbers.

Could anybody help, any suggestions what should i look for?

Thanx

If you're using VC7.1, the compiler supports the Intel-defined intrinsics
for SSE(2) and MMX access. See
