The DP 1.4 Receiver Subsystem is a MAC subsystem which works with a GT Quad Base Controller (PHY) to create a video connectivity system. The DP 1.4 Receiver Subsystem is tightly coupled with the Xilinx PHY Controller, which itself is independent and offers flexible architecture with multiple-protocol support. Both the MAC and PHY are dynamically programmable through the AXI4-Lite interface.
