Synopsis
_mm512_maskz_cvtxph_ps(__mmask16 k, __m256h a);
Description
Convert packed half-precision (16-bit) floating-point elements in "a" to packed single-precision (32-bit) floating-point elements, and store the results in "dst" using zeromask "k" (elements are zeroed out when the corresponding mask bit is not set).
Operation
FOR j := 0 to 15
IF k[j]
dst.fp32[j] := Convert_FP16_To_FP32(a.fp16[j])
ELSE
dst.fp32[j] := 0
FI
ENDFOR
dst[MAX:512] := 0
