MMX was an instruction set added by Intel to its processor lineup in the mid 1990’s. It was marketed as a parallelization technology (it wasn’t) that would accelerate your games (it didn’t). Offering an integer-only instruction set to a world that had largely moved on to floating point wasn’t particularly interesting or useful (though it did have a few fun applications), but that didn’t stop me from writing about it a long long time ago here. I won’t be elaborating further on that. Instead, I’d much rather go over the other MMX, also known as 2010.
