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 。
在實際的研製過程中，利用cpld的在系統可編程（ isp ）技術和基於vhdl語言的可編程邏輯器件設計技術實現了視頻數據採集卡的控制模塊。在視頻的a / d轉換模塊，用匯編程序模擬i2c總線對初始化a / d轉換晶元。針對大容量數據採集，採用了雙緩沖技術解決wndows操作系統下難以申請到大容童連續內存的間題。 -
Then, it illustrates some important problems and technologies, including the information modeling of part, object - oriented designing of feature modeling, the layout and designing of process database, the development of two process designing tools - process dictionary and technician, the implementing of three key technologies in process designing module - template technology, drawing technology of process drawings, generating and printing technology of process card, etc
