The AI Engine to NoC interface tile, in addition to the AXI4-Stream interface capability, also contains paths to connect to the horizontal NoC (HNoC). Looking from the AI Engine, there are four streams from the AI Engine to the NoC, and four streams from the NoC to the AI Engine. From a bandwidth perspective each AI Engine to NoC interface tile can direct traffic between the HNoC and the AXI4-Stream switch.
Tip: The actual total
bandwidth can be limited by the number of horizontal and vertical channels available
in the device and also the bandwidth limitation of the NoC.
