Set Intrinsics (MMX™ technology)
This topic summarizes the MMX™ technology intrinsics.
To use these intrinsics, include the immintrin.h file as follows:
#include <immintrin.h>
In the descriptions regarding the bits of the MMX™ register, bit 0 is the least significant and bit 63 is the most significant.
