【Abstract】 A design of image acquisition card based on FPGA is presented,in which high-speed fiber-optic and PCI Express bus technology are integrated,and multi-layered protocols of PCI Express and Aurora protocol are applied for data management on the fiber and PCI Express bus.Algorithms in the FPGA use "pre-conversion" and "double threshold" strategies to manage and optimize the data processes across high-speed fiber modules and PCI Express module.The experiments show that it achieves good real-time transfer performance as expected.更多还原
