The communication described in the previous section is inside an AI Engine tile or between two neighboring AI Engine tiles. For non-neighboring AI Engine tiles, a similar communication can be established using the DMA in the memory module associated with each AI Engine tile, as shown in the following figure. The synchronization of the ping-pong buffers in each memory module is carried out by the locks in a similar manner to the AI Engine to AI Engine Data Communication via Shared Memory section. The main differences are increased communication latency and memory resources.
