continuous averaging using VHDL

I have a question related to VHDL programming. I want to calculate the continuous average. My example code is: process (clk, reset) begin if (reset = '1') then state<=idle; out-v...

Yes I can see the sum building up soon and avg taking values. One observation during hardware testing is when I increase the number of samples from 128 to 256, I receive the ADC current values slowly. The less the number of samples, the faster I get the averaged values on GUI. But the values I receive is always like 4mA, 8mA, 15mA, 25mA....., 100mA, 101mA, 102mA, 100mA, 99mA... I want to recieve only in the small range of 10mA eg.. between 95mA and 105mA. Is there a way that I can discard values such as 4mA, 8mA,.....90mA and recieve the value when it comes in range between 95mA and 105mA. How can I use signaltap in my code?
