@kaz,
I have 2 questions related to the continuous averaging.
First question is related to increasing the number of stages. I want to increase the number of stages from 32 to 1000. I am doing this for stabilizing the ADC current values. Do I have to modify the signal lengths in the following way:

My final conclusion for 1024 average use equation suggested by dsl and modified as follows:
y(n) = y(n-1) - y(n-1)/1024 + x(n)/1024 i.e.
clocked process
sum = sum - sum(20 downto 10) + data_in(11 downto 10); -- use more width for sum if necessary to avoid overflow.
end process;
only two bits of data_in are used so you may lose resolution but it might be just ok.
