AI Engine array configuration is done using a memory-mapped AXI4 over the NoC interface. NoC can support 128-bit transfers. Inside the AI Engine tile, the memory-mapped AXI4 has a 32-bit data transfer rate and can transfer from one to four 32-bit words in burst mode. An example of the configuration time for a typical design on the VCK190 board is shown in the following table.
