Function core::arch::x86_64::_mm512_madd_epi16

pub unsafe fn _mm512_madd_epi16(a: __m512i, b: __m512i) -> __m512i

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

Available on x86-64 and target feature avx512bw only.

Multiply packed signed 16-bit integers in a and b, producing intermediate signed 32-bit integers. Horizontally add adjacent pairs of intermediate 32-bit integers, and pack the results in dst.
