Synopsis
_mm512_mask_cvtt_roundps_epi32(__m512i src, __mmask16 k, __m512 a, int sae);
Description
Convert packed single-precision (32-bit) floating-point elements in "a" to packed 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). [sae_note]
Operation
FOR j := 0 to 15
i := 32*j
IF k[j]
dst[i+31:i] := Convert_FP32_To_Int32_Truncate(a[i+31:i])
ELSE
dst[i+31:i] := src[i+31:i]
FI
ENDFOR
dst[MAX:512] := 0
