Function core::arch::x86::_mm256_dpbusd_epi32

pub unsafe fn _mm256_dpbusd_epi32(src: __m256i, a: __m256i, b: __m256i) -> __m256i

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

Available on (x86 or x86-64) and target feature avx512vnni,avx512vl and x86 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, and store the packed 32-bit results in dst.
