Fue desarrollado a partir de un set introducido en el <a href="/wiki/Intel_i860" title="Intel i860">Intel i860</a>.

Parte frontal.</figcaption></figure> <p>MMX agregó 8 nuevos <a href="/wiki/Registro_(hardware)" title="Registro (hardware)">registros</a> a la arquitectura, conocidos como MM0 al MM7 (en adelante llamados MMn). En realidad, estos nuevos <i>registros</i> son meros alias de los registros de la pila de la <a href="/wiki/FPU" class="mw-redirect" title="FPU">FPU</a> x87. Por ello cualquier cosa que se haga con la pila de la FPU afecta a los registros MMX. A diferencia de la pila de <a href="/wiki/Coma_flotante" title="Coma flotante">coma flotante</a>, los registros MMn son fijos en vez de relativos, por lo que pueden accederse aleatoriamente. </p><p>Cada uno de los registros MMn es un número entero de 64 bits. Sin embargo, uno de los conceptos principales del juego de instrucciones MMX es el concepto del tipo de datos compactados (packed data types), que significa en lugar de usar el registro completo para un solo número entero de 64 bits (palabra cuádruple o quadword), se puede usar para almacenar dos enteros de 32 bits (palabra doble o doubleword), cuatro enteros de 16 bits (palabra o word) u ocho enteros de 8 bits (<a href="/wiki/Byte" title="Byte">byte</a> u octeto). </p><p>Para simplificar el diseño y evitar modificar el sistema operativo para preservar el estado adicional a través de los interruptores de contexto, MMX reutiliza los ocho registros existentes de la FPU. Por ello es muy difícil trabajar con la FPU y MMX a la vez. Para maximizar el rendimiento, los programadores deben utilizar el procesador exclusivamente en un modo o el otro, retrasando todo lo posible el lento paso de un modo a otro. </p> <div
