The CertusPro™-NX DisplayPort (DP) to Peripheral Component Interconnect Express (PCIe®) bridge design demonstrates the functionality of transferring DisplayPort video data to a computer through PCIe with a direct memory access (DMA) engine. This demo is based on the CertusPro-NX PCIe Bridge Board with Linux® operating system (OS) driver support that shows transfer of 4K60 video data to the computer memory. The board renders the data as video on the computer screen using the software driver.
This design requires DisplayPort source, such as laptop or Graphics Processing Unit (GPU), to provide a 4K60 video source to the FPGA. The DisplayPort receiver (RX) receives the video stream and sends the video stream to the PCIe interface through a video bridge. The PCIe Video DMA (VDMA) processes the video data movement between video interfaces and the target central processing unit (CPU) memory. The video data is displayed in a host PC.
