Function serde::lib::core::arch::x86_64::_mm256_dpbusd_epi32

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

🔬This is a nightly-only experimental API. (stdarch_x86_avx512)

Available on x86-64 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.
