A high-speed LVDS acquisition card based on PCI Express

As the third generation of I/O bus, PCI Express provides some very promising features for high speed data acquisition such as electronic measurement and automatic test. According to the special needs of LVDS in the field of Aeronautic measurement and control, a high-speed LVDS acquisition card conforming to PCI Express 1.0a, device drivers and user-level applications under windows system is developed. The design of FPGA+PHY of this card enables the acquisition and transmission of LVDS. Meanwhile, an in-depth research is made at the aspect of interruption and transmission technology related with PCI Express.
