Synopsis
_mm512_mask_cvtxps_ph(__m256h src, __mmask16 k, __m512 a);
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).
Operation
FOR j := 0 to 15
IF k[j]
dst.fp16[j] := Convert_FP32_To_FP16(a.fp32[j])
ELSE
dst.fp16[j] := src.fp16[j]
FI
ENDFOR
dst[MAX:256] := 0
