Instruction
VCVTNEPS2BF16 xmm {z}, ymm
Synopsis
 _mm256_maskz_cvtneps_pbh(__mmask8 k, __m256 a);
Description
Convert packed single-precision (32-bit) floating-point elements in "a" to packed BF16 (16-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 7
	IF k[j]
		dst.word[j] := Convert_FP32_To_BF16(a.fp32[j])
	ELSE
		dst.word[j] := 0
	FI
ENDFOR
dst[MAX:128] := 0
