The main data streams to and from the AI Engine-ML are as follows:
- The AI Engine-ML to PL streaming interface
- GMIO, which is used to make external memory-mapped connections to or from the global memory.
The interface between the PS and AI Engine-ML has a low throughput and is ideal for configuration. The AI Engine-ML-GMIO directly connects to the DDR memory through the AI Engine-ML-NoC master unit (NMU).
The bandwidth of AI Engine-ML GMIO depends on the number of NMUs and DDR memory controllers used in the platform.
