Function core::arch::x86::_mm256_dpwssd_epi32

pub unsafe fn _mm256_dpwssd_epi32(src: __m256i, a: __m256i, b: __m256i) -> __m256i

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

Available on x86 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, and store the packed 32-bit results in dst.
