Integer Vector Intrinsic

The integer vector intrinsic listed here is designed for the Intel® Pentium® 4 processor with Streaming SIMD Extensions 3 (Intel® SSE3). The prototype for this intrinsic is in the
pmmintrin.h
header file.
To use this intrinsic, include the
immintrin.h
file as follows:
#include <immintrin.h>
R
represents the register into which the returns are placed.

_mm_lddqu_si128

__m128i _mm_lddqu_si128(__m128i const *p);
Loads an unaligned 128-bit value. This differs from
MOVDQU
in that it can provide higher performance in some cases. However, it also may provide lower performance than
MOVDQU
if the memory value being read was just written.
