Intrinsics for Intel® Advanced Vector Extensions 512 (Intel® AVX-512) 4VNNIW Instructions

The prototypes for Intel® Advanced Vector Extensions 512 (Intel® AVX-512) 4VNNIW instruction intrinsics are located in the zmmintrin.h header file.
To use these intrinsics, include the
immintrin.h
file as follows:
#include <immintrin.h>
_mm512_4dpwssd_epi32
__mm512i _mm512_4dpwssd_epi32 (__m512 c, __m512 a0, __m512 a1, __m512 a2, __m512 a3, __m128 * b)
variable

a
n
first source block 4 vectors
b
pointer to the second source block
c
third source; accumulator
Instructions: vp4dpwssd zmm1, zmm2+3, m128
Computes 4 vector source-block dot-products of two signed word operands with doubleword accumulation in
c
. The memory operand is sequentially selected in each of the four steps.
