_mm256_dpbuud_epi32 in core::arch::x86 - Rust
Description: Multiply groups of 4 adjacent pairs of unsigned 8-bit integers in a with corresponding unsigned 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.
