pub unsafe fn _mm256_maskz_dpwssds_epi32(

    src: __m256i, 
    a: __m256i,

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

Available on x86-64 and target feature avx512vnni,avx512vl only.

Multiply groups of 2 adjacent pairs of signed 16-bit integers in a with corresponding 16-bit integers in b, producing 2 intermediate signed 32-bit results. Sum these 2 results with the corresponding 32-bit integer in src using signed saturation, and store the packed 32-bit results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
