Synopsis
_mm512_maskz_cvtt_roundpd_epu32(__mmask8 k, __m512d a, int sae);
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 zeromask "k" (elements are zeroed out when the corresponding mask bit is not set). [sae_note]
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] := 0
FI
ENDFOR
dst[MAX:256] := 0
