# Function core::arch::x86::_mm_maskz_dpbf16_ps
[−][src]

    pub unsafe fn _mm_maskz_dpbf16_ps(
        k: __mmask8,
        src: __m128,
        a: __m128bh,
        b: __m128bh
    ) -> __m128

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86 and target feature `avx512bf16,avx512vl` only.

Compute dot-product of BF16 (16-bit) floating-point pairs in a and b, accumulating the intermediate single-precision (32-bit) floating-point elements with elements in src, and store the results in dst using zeromask k (elements are zeroed out when the corresponding mask bit is not set).
