The Dynamic Function eXchange (DFX) Decoupler IP provides logical isolation capabilities for DFX designs. One or more DFX Decoupler cores can be used to make the interface between a Reconfigurable Partition (RP) and the static logic safe from unpredictable activity while dynamic reconfiguration is occurring. When active, user-selected signals crossing between the RP and the static logic are driven to user configurable values. When inactive, signals are passed unaltered. DFX Decoupler cores can be connected to the DFX Controller IP or custom user controllers to create a complete Dynamic Function eXchange management solution.
The DFX Decoupler core can be customized for the number of interfaces, type of interfaces, decoupling functionality, status and control. AXI-based interfaces are natively supported; easily and efficiently enable AXI4-Stream based control, AXI4-Stream based status, or AXI4-Lite based status and control.
