so basically you want to add in that order:

taps = 4, add [0] only

taps = 8, add [0] +[1]

taps = 16, add [0]+[1]+[2]+[3]...etc

but your first generate statement is not doing that.

I suggest you run a hardware counter as integer say from 0 to taps/4-1 and so it adjusts to number of taps. Then set your logic such that count is used as index.

that is something like this: sum <= sum+addition(count);

thus the feedback loop will take care of it as the counter runs.
