Synopsis
_mm512_mask_cvttpd_epu32(__m256i src, __mmask8 k, __m512d a);
Description
Convert packed double-precision (64-bit) floating-point elements in "a" to packed unsigned 32-bit integers with truncation, and store 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 := 32*j
l := 64*j
IF k[j]
dst[i+31:i] := Convert_FP64_To_UInt32_Truncate(a[l+63:l])
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:256] := 0
