Synopsis
_mm512_maskz_cvtneps_pbh(__mmask16 k, __m512 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 15
IF k[j]
dst.word[j] := Convert_FP32_To_BF16(a.fp32[j])
ELSE
dst.word[j] := 0
FI
ENDFOR
dst[MAX:256] := 0
