Detailed Description

This class aggregates the three AXI protocol interfaces (AXI-Lite, AXI-Full, and AXI-Stream) available on supported devices.

An instance of this class is obtained by calling OpalKelly::FrontPanel::GetFPGADataPortAXI().

Warning

AXI operations are not thread safe. Operations across the AXI-Lite, AXI-Full, and AXI-Stream sub-interfaces are carried over a single shared connection to the device, so concurrent AXI calls on the same device must be serialized with external synchronization.

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.
