 In this case, instead of using two levels, one with a tbl24 and a second with a tbl8, 14 levels are used.

 By splitting the process in different tables/levels and limiting the number of tbl8s,
 we can greatly reduce memory consumption while maintaining a very good lookup speed (one memory access per level).
