Synopsis
_mm512_maskz_cvtepi8_epi16(__mmask32 k, __m256i a);
Description
Sign extend packed 8-bit integers in "a" to packed 16-bit integers, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 31
i := j*8
l := j*16
IF k[j]
dst[l+15:l] := SignExtend16(a[i+7:i])
ELSE
dst[l+15:l] := 0
FI
ENDFOR
dst[MAX:512] := 0
