Synopsis
_mm512_fmadd233_epi32(__m512i a, __m512i b);
Description
Multiply packed 32-bit integer 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
