Computes sum of absolute differences between extended packed unsigned values of two vectors. The corresponding Intel® AVX2 instruction is VPSADBW.
extern __m256i _mm256_sad_epu8(__m256i s1, __m256i s2); |
s1 |
integer source vector used for the operation |
s2 |
integer source vector used for the operation |
Computes the absolute value of the difference of packed groups of eight unsigned byte integers from the source vectors s1 and s2. Four blocks of eight differences are stored at specific locations in the destination vector. Remaining bits in the destination vector are set to zero.
Result of the single sum-absolute-difference operation.
