Synopsis
_mm256_cvtph_ps(__m128i a);
Description
Convert packed half-precision (16-bit) floating-point elements in "a" to packed single-precision (32-bit) floating-point elements, and store the results in "dst".
Operation
FOR j := 0 to 7
i := j*32
m := j*16
dst[i+31:i] := Convert_FP16_To_FP32(a[m+15:m])
ENDFOR
dst[MAX:256] := 0
