process inside another process?

okk..The value of the signals will change only once the process ends. But i want the q and k value to change each timew it enters the j for loop..this is the code that needs to be modified so that k and q values are updated each time it enters the loop.

library ieee;

use ieee.std_logic_1164.all;

use ieee.std_logic_unsigned.all;

use ieee.numeric_std.all;

entity ber is

port ( clk : in std_logic

);

end ber;

architecture ar of ber is

type data is array (0 to 11) of std_ulogic;

signal d: data; -- give the input data bit by bit

signal q:std_logic_vector(0 to 3):="0001";

signal k:std_logic_vector(0 to 3):="0000";

signal t: std_logic:='0';

begin

p2: process(clk)

variable count : integer := -1;

begin

if rising_edge(clk) then

for j in 0 to 2 loop

q<=(q(2)xor q(3)) &q(0)&q(1)&q(2); -- LFSR

k<=q;

end if;

for t in 0 to 3 loop

if (k(t) /= d(t+(4*j))) then

count := count+1;

end if;

end loop;

end loop;

end process p2;

end ar;
