# Function core::arch::x86_64::_mm256_sad_epu8
1.27.0[−][src]

    pub unsafe fn _mm256_sad_epu8(a: __m256i, b: __m256i) -> __m256i

This is supported on x86-64 and target feature `avx2` only.

Computes the absolute differences of packed unsigned 8-bit integers in `a` and `b`, then horizontally sum each consecutive 8 differences to produce four unsigned 16-bit integers, and pack these unsigned 16-bit integers in the low 16 bits of the 64-bit return value
