Synopsis
_mm512_maskz_cvtt_roundph_epu16(__mmask32 k, __m512h a, int sae);
Description
Convert packed half-precision (16-bit) floating-point elements in "a" to packed unsigned 16-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 31
IF k[j]
dst.word[j] := Convert_FP16_To_UInt16_Truncate(a.fp16[j])
ELSE
dst.word[j] := 0
FI
ENDFOR
dst[MAX:512] := 0
