pub unsafe fn _mm512_mask_dpbusds_epi32(
    src: __m512i,
    k: __mmask16,
    a: __m512i,
    b: __m512i
) -> __m512i

🔬This is a nightly-only experimental API. (stdsimd #48556)

Available on (x86 or x86-64) and target feature avx512vnni only.

Multiply groups of 4 adjacent pairs of unsigned 8-bit integers in a with corresponding signed 8-bit integers in b, producing 4 intermediate signed 16-bit results. Sum these 4 results with the corresponding 32-bit integer in src using signed saturation, and store the packed 32-bit results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
