The apparatus includes a comparator unit (C) which is activatable to create or update, in a second memory unit (M2), the bank of groups of data items on the basis of the groups of data items in the first memory unit (M1), or in some other memory unit, each group of data items in the second memory unit after the update is given a priority value. The priority value of a group of data items in the second memory unit is calculated on the basis of the number of presences of the group of data items in the first memory unit or some other memory unit. The comparator unit, on the basis of the priority values, selects the group of data items in the second memory unit, whose initial data items conforms to the entire group of data items in question in the first memory unit. |
