# Function core::arch::x86_64::_mm_maskz_dpbusd_epi32
[−][src]

    pub unsafe fn _mm_maskz_dpbusd_epi32(
        k: __mmask8,
        src: __m128i,
        a: __m128i,

    ) -> __m128i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512vnni,avx512vl` only.

Multiply groups of 4 adjacent pairs of unsigned 8-bit integers in a with corresponding signed 8-bit integers in b, producing 4 intermediate signed 16-bit results. Sum these 4 results with the corresponding 32-bit integer in src, and store the packed 32-bit results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
