Synopsis
_mm256_mask_abs_epi16(__m256i src, __mmask16 k, __m256i a);
Description
Compute the absolute value of packed signed 16-bit integers in "a", and store the unsigned results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 15
i := j*16
IF k[j]
dst[i+15:i] := ABS(a[i+15:i])
ELSE
dst[i+15:i] := src[i+15:i]
FI
ENDFOR
dst[MAX:256] := 0
