# Function core::arch::x86_64::_mm512_sad_epu8[−][src]

    pub unsafe fn _mm512_sad_epu8(a: __m512i, b: __m512i) -> __m512i

🔬 This is a nightly-only experimental API. (`stdsimd` #48556)
This is supported on x86-64 and target feature `avx512bw` only.

Compute the absolute differences of packed unsigned 8-bit integers in a and b, then horizontally sum each consecutive 8 differences to produce eight unsigned 16-bit integers, and pack these unsigned 16-bit integers in the low 16 bits of 64-bit elements in dst.
