Well, there are some things that might be useful:
1. You assign to an array in a for loop. That usually is a sign for something inefficient.
2. Your use of $#i will put all data in one array, so you technically don't have an AoA, but just an array.
3. You can loose the push/pop mechanism, replace that with a map.

This is how I would write that: 

my @AoA = map{ [split] } <DATA>;
print join "\n", map{ join ',' @$_ } @AoA;

You could also turn to Supersplit code.

Have fun,
