Abstract:A design project and function realization of a kind of high-speed data acquisition card
based on PCI Express bus is introduced in this paper. It presents the structure and circuit cells of
the system, emphasizes the key technique of system hardware design and the control logic of local
bus, discusses in detail the development of device driver based on DriverWorks and the design of
super application software. Verified by practice, this system can be used to receive the high-speed
data down from satellite. And can also be applied to other high-speed data acquisition and
processing system.
