pub unsafe fn _mm_maskz_maddubs_epi16(k: u8, a: __m128i, b: __m128i) -> __m128i
🔬 This is a nightly-only experimental API. (
stdsimd)This is supported on x86-64 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 zeromask k (elements are zeroed out when the corresponding mask bit is not set).
