Synopsis
_mm512_mask_cvtepu32lo_pd(__m512d src, __mmask8 k, __m512i v2);
Description
Performs element-by-element conversion of the lower half of 32-bit unsigned integer elements in "v2" to packed double-precision (64-bit) floating-point elements, storing the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 7
i := j*32
l := j*64
IF k[j]
dst[l+63:l] := Convert_Int32_To_FP64(v2[i+31:i])
ELSE
dst[l+63:l] := src[l+63:l]
FI
ENDFOR
dst[MAX:512] := 0
