Function _mm_sad_epu8
#[target_feature(enable = "sse2")]
pub fn _mm_sad_epu8(a: __m128i, b: __m128i) -> __m128iSum the absolute differences of packed unsigned 8-bit integers.
Computes the absolute differences of packed unsigned 8-bit integers in a
and b, then horizontally sum each consecutive 8 differences to produce
two unsigned 16-bit integers, and pack these unsigned 16-bit integers in
the low 16 bits of 64-bit elements returned.
