The segmented AXI4-Stream bus must be used with the enhanced scheduling algorithm described in the Interlaken Protocol Definition, Revision 1.2. Among the requirements of this algorithm are:

  • All bursts except the last two must be equal to BurstMax.
  • Bursts must be written to the AXI4-Stream bus in their entirety before changing channels or writing the next burst.
  • The last two bursts of a packet are delineated using tx_axis_tuser_bctl<M> and by knowing the value of BurstMin.
  • If user logic does not implement enhanced scheduling, then the ILKNF subsystem will perform it with BurstMin of 64 bytes.
