VPABSB zmm {k}, zmm
Synopsis
_mm512_mask_abs_epi8(__m512i src, __mmask64 k, __m512i a);
Description
Compute the absolute value of packed signed 8-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 63
i := j*8
IF k[j]
dst[i+7:i] := ABS(a[i+7:i])
ELSE
dst[i+7:i] := src[i+7:i]
FI
ENDFOR
dst[MAX:512] := 0
