===Introduction===
MMX is a SIMD technology (single instruction, multiple data) introduced by Intel with ther P5 "Pentium" processor line.
===Detection===
To detect MMX
<source lang="asm">
;Check CPUID.01h EDX.MMX (EDX.23)
mov eax, 0x1 ;0x.. is not needed, but standardizes
cpuid
test edx, 1<<23 ;EDX.MMX
jnz .MMX ;If no jump MMX is not present
</source>
===Use today===
It is unlikely that you will come across any MMX code today, as it has been superceded by [[SSE]], and compilers compile SSE code. However, it may be wowrthwile to be aware of MMX.
