Instruction
VCVTNEPS2BF16 xmm {k}, xmm
Synopsis
_mm_mask_cvtneps_pbh(__m128bh src, __mmask8 k, __m128 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 writemask "k" (elements are copied from "src" when the corresponding mask bit is not set).
Operation
FOR j := 0 to 3
IF k[j]
dst.word[j] := Convert_FP32_To_BF16(a.fp32[j])
ELSE
dst.word[j] := src.word[j]
FI
ENDFOR
dst[MAX:128] := 0
