Function core::arch::x86_64::_mm256_dpwssds_epi32

pub unsafe fn _mm256_dpwssds_epi32(
    src: __m256i,
    a: __m256i,
    b: __m256i
) -> __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.
