Synopsis
_mm256_cvtne2ps_pbh(__m256 a, __m256 b);
Description
Convert packed single-precision (32-bit) floating-point elements in two vectors "a" and "b" to packed BF16 (16-bit) floating-point elements, and store the results in single vector "dst".
Operation
FOR j := 0 to 15
IF j < 8
t := b.fp32[j]
ELSE
t := a.fp32[j-8]
FI
dst.word[j] := Convert_FP32_To_BF16(t)
ENDFOR
dst[MAX:256] := 0
