Pci Bus-based Video Data Acquisition System

In the dissertation,we discribe the implementation of large capability video data acquisition system based on PCI bus of computer 。The system is composed of data acquisiton card and corresponding software。The data acquisiton card include two acquisition channels,8-bit digitization at rates up to 13.5MHz。Frist ,the architecture of the video data acqusition system is studied。Then ,the function and implementation methode of each module are introduced in detail。 The control module of the video data acqusition card is implemented by using of the ISP technology of CPLD and VHDL programming technology。The A/D converter used assembler to implement the initialazation programe。And the double buffer technology is used for large capability data acqusition.because a contiously large memory is difficult to apply in Windows operating system。Finally we use Broland C++ to introduced the devleoping procedure of drivers。...
