This code is pretty much the same as before. There are still several problems:

d(n) gets a value every 128 clocks, and takes 8192 clocks to fill. Also- d(n) is always the old value of temp_approx because you registered it.

In integer arithmatic, 1/2 = 0. So your temp_approx value will be 2*(n+2).

You should see all of this in your simulation waveforms.
