Intrinsics for Bitwise Logical Operations

The prototypes for Intel® Advanced Vector Extensions 512 (Intel® AVX-512) intrinsics are located in the
zmmintrin.h
header file.
To use these intrinsics, include the
immintrin.h
file as follows:
#include <immintrin.h>

variable
definition
k
writemask used as a selector
a
first source vector element
b
second source vector element
src
source element to use based on writemask result
_mm512_and_epi32
extern __m512i __cdecl _mm512_and_epi32(__m512i a, __m512i b);
Computes the bitwise
AND
of packed 32-bit integers in
a
and

Computes the bitwise
AND
of packed 32-bit integers in
a
and
b
, and stores the result using zeromask
