This interface provides byte-level, burst-capable access to the FPGA over the AXI-Full protocol. It supports configurable burst lengths and variable datapath widths.
An instance of this class is obtained via OpalKelly::FPGADataPortAXI::GetAXIFull().
- Note
- The AXI data port is available on FP-Gen3-USB devices. Such devices report okDATAPORT_AXI in okTDeviceInfo::dataport. OpalKelly::FrontPanel::GetFPGADataPortAXI() returns UnsupportedFeature on all other devices.
