Abstract:
1. A method for assembling data packets for isochronous data transmission via a data bus, a data format for the isochronous data transmission being defined in an isochronous data format header of a bus packet, comprising the steps of: writing the isochronous data format header to a special register and to a buffer memory for the data packets when the isochronous data transmission is set up in a data transmitting device; attaching useful data of the data packet to the isochronous data format header in the buffer memory; and taking both the isochronous data format header and the useful data from said buffer memory for data transmission; the isochronous data format header containing a comparison value for data counting, in particular data block counting, further comprising the steps of: updating the comparison value for data counting in the isochronous data format header, which is entered in the special register, when the data of said data packet are written to the buffer memory; and copying the updated isochronous data format header to the buffer memory at a next free location for a data packet, after completion of said data packet in the buffer memory.
