# 1.27.0[−][src]Function core::arch::x86_64::_mm256_mpsadbw_epu8

    pub unsafe fn _mm256_mpsadbw_epu8(a: __m256i, b: __m256i, imm8: i32) -> __m256i

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

Computes the sum of absolute differences (SADs) of quadruplets of unsigned 8-bit integers in `a` compared to those in `b`, and stores the 16-bit results in dst. Eight SADs are performed for each 128-bit lane using one quadruplet from `b` and eight quadruplets from `a`. One quadruplet is selected from `b` starting at on the offset specified in `imm8`. Eight quadruplets are formed from sequential 8-bit integers selected from `a` starting at the offset specified in `imm8`.
