| Abstract: | This paper presents the design of DTV TS acquisition card based on PCI Express bus. The overall design, hardware interface and software program of the acquisition card are introduced in detail, focusing on how to implement high-speed DMA data transfer based on the high bandwidth of PCI Express bus. At last, we debugged and verified the card using SignalTap II in Quartus II 13.0, and the experimental results show that the design is adequate for DTV TS acquisition. |
