    Publication number: 20020109700
    Abstract: A method for modifying a selected data portion (8) of a data item (10) with a bit pattern (36) is disclosed. Said method identifies a data portion (8) to be modified. Said method further selects a field (38) by accessing a plurality of fields (30). Said fields (30) include a plurality of recurring bit patterns (36). Adjacent fields (38, 40) have identical bit patterns offset by at least one bit. Said method selects a mask (58) to obtain a selected one of said bit patterns (36) in said selected field (38) that is aligned with said identified data portion (8). Said method modifies said identified data portion (8) by performing a predetermined bit operation on said identified data portion (8) with said selected one of said bit patterns (36).
