Synopsis
 _mm512_fmadd233_ps(__m512 a, __m512 b);
Description
Multiply packed single-precision (32-bit) floating-point elements in each 4-element set of "a" and by element 1 of the corresponding 4-element set from "b", add the intermediate result to element 0 of the corresponding 4-element set from "b", and store the results in "dst".
Operation
FOR j := 0 to 15
	i := j*32
	base := (j & ~0x3) * 32
	scale[31:0] := b[base+63:base+32]
	bias[31:0]  := b[base+31:base]
	dst[i+31:i] := (a[i+31:i] * scale[31:0]) + bias[31:0]
ENDFOR
dst[MAX:512] := 0
