Synopsis
_mm512_mask_cvt_roundps_pd(__m512d src, __mmask8 k, __m256 a, int sae);
Description
Convert packed single-precision (32-bit) floating-point elements in "a" to packed double-precision (64-bit) floating-point elements, and store the results in "dst" using writemask "k" (elements are copied from "src" when the corresponding mask bit is not set). [sae_note]
Operation
FOR j := 0 to 7
i := 64*j
l := 32*j
IF k[j]
dst[i+63:i] := Convert_FP32_To_FP64(a[l+31:l])
ELSE
dst[i+63:i] := src[i+63:i]
FI
ENDFOR
dst[MAX:512] := 0
