The NMU and NSU support AXI4/AXI4-Stream protocols interfacing with the NoC Master and the NoC Slave. Between a NoC master request and a response return, multiple AXI conversions including transformations of the AxAddr, AxSize, AxLen, and choppings are performed. This section covers the AXI conversion overview, the NoC AXI support/restriction and the NoC Master/Slave configuration assumptions for AXI conversion.
