Work with Floating point core in Xilinx Web Pack 8.1i

i have the following proceed.
in Xilinx webPac 8.1i Add flaoting point Core and also add its component and its instation. there is no error.
i have made a three signal of 32 bit and assign value to Core A , B and Result signal.
now the problem is i am reading the value for A and B signal from RegdataIn and then directly result of core is Assign to Result Signal and give to RegDataOut. but the Result i am getting is not Correct.
here i am showing my code…

---- this is Component Map
component floatip
port (
a: IN std_logic_VECTOR(31 downto 0);
b: IN std_logic_VECTOR(31 downto 0);
operation_nd: IN std_logic;
operation_rfd: OUT std_logic;
clk: IN std_logic;
sclr: IN std_logic;
result: OUT std_logic_VECTOR(31 downto 0);
invalid_op: OUT std_logic;
divide_by_zero: OUT std_logic;
rdy: OUT std_logic);
end component;

—Declare Signal for Process
signal SFloatA : std_logic_vector(31 downto 0);
signal SFloatB : std_logic_vector(31 downto 0);

signal SNewData:std_logic;
signal SReadyForData:std_logic;
signal SInvalid_Op:std_logic;
signal SDivide_Error:std_logic;
signal SReady:std_logic;

signal SConstR : std_logic_vector(31 downto 0);
signal SInitP : std_logic_vector(31 downto 0);
signal SDivResutl : std_logic_vector(31 downto 0);

Helllo sir please give me answer what is the Wrong
