4.12. AXI-ST Multiple Packet Mode

The AXI-ST Multiple Packet Mode is supported for MACsec and IPsec profiles. The AXI specification defines the Multiple Packet Mode as following:
  • No two start of packet (SOP) within the same clock cycle.
  • No two end of packet (EOP) within the same clock cycle.
  • Two packets packed within the same clock cycle are allowed as long as both packets are from the same stream.
