6.1.3. User Interface Data Streaming

The data streaming into the MACsec IP through the user interfaces (Common/Controlled/Uncontrolled) can be either in full packet or 64B word per port/stream. The AXI-ST TID signal is used to indicate the port/stream where a request originates from. If your interface data width is configured to 64/128/256b, data streaming per port/stream can be 8/16/32 bytes and an accumulation of 512b is done prior to the Crypto block for data framing before sending it into the Crypto block.
