Instruction
VCVTPH2PD xmm {z}, xmm
Synopsis
 _mm_maskz_cvtph_pd(__mmask8 k, __m128h a);
Description
Convert packed half-precision (16-bit) floating-point elements in "a" to packed double-precision (64-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 1
	IF k[j]
		dst.fp64[j] := Convert_FP16_To_FP64(a.fp16[j])
	ELSE
		dst.fp64[j] := 0
	FI
ENDFOR
dst[MAX:128] := 0
