Synopsis
_mm512_mask_cvt_roundps_ph(__m256i src, __mmask16 k, __m512 a, int rounding);
Description
Convert packed single-precision (32-bit) floating-point elements in "a" to packed half-precision (16-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). [round2_note]
Operation
FOR j := 0 to 15
i := 16*j
l := 32*j
IF k[j]
dst[i+15:i] := Convert_FP32_To_FP16(a[l+31:l])
ELSE
dst[i+15:i] := src[i+15:i]
FI
ENDFOR
dst[MAX:256] := 0
