Synopsis
_mm512_fmadd_ph(__m512h a, __m512h b, __m512h c);
Description
Multiply packed half-precision (16-bit) floating-point elements in "a" and "b", add the intermediate result to packed elements in "c", and store the results in "dst".
Operation
FOR j := 0 to 31
dst.fp16[j] := (a.fp16[j] * b.fp16[j]) + c.fp16[j]
ENDFOR
dst[MAX:512] := 0
