|
|
The Xilinx LogiCORE Partial Reconfig(PR) Decoupler manages one or more
|
|
decouplers/fpga bridges. The controller can decouple/disable the bridges
|
|
which prevents signal changes from passing through the bridge. The controller
|
|
can also couple / enable the bridges which allows traffic to pass through the
|
|
bridge normally.
|
|
Xilinx LogiCORE Dynamic Function eXchange(DFX) AXI shutdown manager Softcore
|
|
is compatible with the Xilinx LogiCORE pr-decoupler. The Dynamic Function
|
|
eXchange AXI shutdown manager prevents AXI traffic from passing through the
|
|
bridge. The controller safely handles AXI4MM and AXI4-Lite interfaces on a
|
|
Reconfigurable Partition when it is undergoing dynamic reconfiguration,
|
|
preventing the system deadlock that can occur if AXI transactions are
|
|
interrupted by DFX.
|
|
Please refer to fpga-region.txt and fpga-bridge.txt in this directory for
|
|
common binding part and usage.
