Function core::arch::x86::_mm_dpwsuds_epi32

pub unsafe fn _mm_dpwsuds_epi32(src: __m128i, a: __m128i, b: __m128i) -> __m128i

🔬This is a nightly-only experimental API. (stdarch_x86_avx512 #111137)

Available on (x86 or x86-64) and target feature avxvnniint16 and x86 only.

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 with signed saturation, and store the packed 32-bit results in dst.
