Function core::arch::x86::_mm256_mask_maddubs_epi16

pub unsafe fn _mm256_mask_maddubs_epi16(
    src: __m256i, 
    k: __mmask16, 
    a: __m256i, 
    b: __m256i
) -> __m256i

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

This is supported on x86 and target feature avx512bw,avx512vl only.

Multiply packed unsigned 8-bit integers in a by packed signed 8-bit integers in b, producing intermediate signed 16-bit integers. Horizontally add adjacent pairs of intermediate signed 16-bit integers, and pack the saturated results in dst using writemask k (elements are copied from src when the corresponding mask bit is not set).
