Method and apparatus for the determination of a repetitive bit value pattern

The invention discloses a method and an apparatus for the determination of a repetitive bit value pattern. A repetitive bit value pattern associated to a predetermined bit position of a sequence of data words (2), the data words comprising two or more bits in a bit order, a bit position describing a position within the bit order being indicative of a value represented by the bit at the bit position, can be determined from program loop information, the program loop information comprising a program expression for determining an updated data word of the sequence of data words (2). Using the predetermined bit position, a sequence length value (8) associated to the predetermined bit position is determined. The program expression is evaluated (6) for a number of loop iterations indicated by the sequence length value (8), to obtain updated bit values associated to the predetermined bit position. The repetitive bit value pattern is determined using the updated bit values of the number of loop iterations.
