Intel MMX
Intel MMX Technology merupakan sebuah ekstensi instruksi mikroprosesor yang membantu proses perhitungan pada beberapa aplikasi, terutama aplikasi multimedia, game, editor gambar dua dimensi, kompresi/dekompresi, enkripsi, dan aplikasi lainnya. Banyak orang menyebut MMX ini adalah sebuah singkatan dari Multimedia Extension atau Matrix Math Extension atau Multiple Math Extension, meski Intel sendiri tidak menyatakan bahwa MMX adalah sebuah singkatan.
Instruksi MMX ditambahkan pertama kali pada prosesor Intel Pentium MMX yang dirilis tahun 1997, yang terdiri dari 57 instruksi baru yang ditambahkan. Semua instruksi tersebut merupakan instruksi yang dalam istilah Arsitektur Komputer disebut dengan SIMD (Single Instruction Multiple Data).
