Abstract

The invention relates to a way of implementing the so-called “late” check according to IEC 61883 in a link layer IC for the IEEE 1394 Serial Bus in a way which is favourable in terms of expenditure. According to the invention, a specific time model is used which, during the checking of the up-to-dateness of a data packet by comparison with the current bus time, also substantially simplifies the necessary comparison operations by virtue of the fact that it is possible to represent only sections of the time axis by means of a data word with limited bit length.
