PCIe_CameraLink Image Simulation Source Based on XILINX K7 XC7K325T
PCIe_CameraLink Image Simulation Source Based on XILINX K7 XC7K325T
1. Board
This image analog source board is based on Xilinx's FPGAXC7K325T-2FFG900 chip and is pin_to_pin compatible with FPGAXC7K410T-2FFG900. The main function is to realize that the system can receive the noise data of the external camera and input it to the upper computer through the PCI-E interface through the image conversion board.
2. functions and technical indicators:
1. It is used to receive images generated by the upper computer (including a wide test field image and a high-score image), and send the two images to external devices in Cameralink format or LVDS format at the same time;
2. The image conversion board receives the noise data sent by the external camera and transmits it to the upper computer for processing;
3. The image conversion board needs to receive the second pulse signal sent by the test equipment and feed it back to the upper computer through interruption;
The receiver board indicators are shown in the following table.
