you generate it, like you would any enable: 


signal cnt : unsigned(7 downto 0);
process(clk, reset)
begin
  if reset = '1' then
    cnt <= x"00";
    en <= '0';
  elsif rising_edge(clk) then
    
    --Create an enable that is high once every 256 clocks
    if cnt = 0 then  
      en <= '1';
    else
      en <= '0';
    end if;
  
    cnt <= cnt + 1;
  end if;
end process;
