[−][src]Macro safe_arch::multi_packed_sum_abs_diff_u8_m256i
This is supported with target feature
avx2
only.Computes eight u16
"sum of absolute difference" values according to the
bytes selected.
- This essentially works like two
multi_packed_sum_abs_diff_u8_m128i
uses happening at once, the "low" portion works on the lower 128 bits, and the "high" portion works on the upper 128 bits.
let a = m256i::from([5_u8; 32]); let b = m256i::from([7_u8; 32]); // let c: [u16; 16] = multi_packed_sum_abs_diff_u8_m256i!(a, b, low a 0, low b 0, high a 1, high b 1).into(); assert_eq!(c, [8_u16; 16]);
