  1. Not all of the AI Engine interface tiles are connected to the PL.
  2. Assumes all PL AXI4-Stream interfaces run at maximum frequency.
  3. AI Engine array interface tiles have interfaces to both the PL and NoC. Routing to these interfaces share the same streaming interconnect resources inside the AI Engine array.
  4. Total bandwidth includes horizontal interface usage.
Note: For further information on the AI Engine array interface to the PL interface, see the AI Engine Array Interface Topology figure and AI Engine to PL Interface Bandwidth Performance table in the Versal Adaptive SoC AI Engine Architecture Manual (AM009).
