_mm_dpwsud_epi32 in core::arch::x86 - Rust
Description: Multiply groups of 2 adjacent pairs of signed 16-bit integers in a with corresponding unsigned 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.
