Function core::arch::x86::_mm256_maddubs_epi16

pub unsafe fn _mm256_maddubs_epi16(a: __m256i, b: __m256i) -> __m256i

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

This is supported on x86 and target feature avx2 only.

Vertically multiply each unsigned 8-bit integer from a with the corresponding signed 8-bit integer from b, producing intermediate signed 16-bit integers. Horizontally add adjacent pairs of intermediate signed 16-bit integers
