  1. The main contents of the paper are : i the relationship of the accurateness of calculation, complexity of calculation and hardware resources of the 5 - 3 dwt ; ii the basic theory of pci data transmission the controlling of the host to client and the data exchanging ; iii configuration of the video decoder saa7114h to implement the transformation of the analog to the digital image ; iv image acquisition, compression and transmission from the host to the acquisition board by the component of field programmable gate array ( fpga ), digital signal processor ( dsp ) with the controller of pci and video decoder saa7114h

    Pci的數據傳輸原理，外部主機如何控制從屬設備以及如何進行數據交換。配置視頻解碼器saa7114h ，實現模擬ccd攝像頭模擬數據到數字數據的轉換，實現採集的功能。用fpga 、 saa7114h和集成pci介面的dsp實現圖像的採集、壓縮以及從採集板到主機的傳輸。
  2. It ’ s a 16 / 32bits risc cpu based on arm920t ip core, which is highly integrated and powerful. this cpu has a lot of peripheral interfaces and i / o ports, which will facilitate our system design. the asic ime6400 is a system level chip which supports the multi - channel mepg4 video / audio compression. in our design, it ’ s served as an video compression oriented co - processor working under the control of s3c2410x. s3c2410x will do the job of importing the other vehicle traveling data such as analog and switch signals

    在筆者設計的系統中， ime6400作為專門進行數字視頻信號壓縮的協處理器，與s3c2410x協同工作，完成視頻信號的獲取，壓縮等工作;同時利用晶元的片內外設（如ad轉換器和i / o口） ，完成汽車行駛過程中開關量和模擬量的獲取和存儲，以滿足一個記錄儀的基本功能需求。
  3. The main processor we use is tm1300 produced by philips co. tmlsoo has a lot of advantages such as it has vliw which is suited to processing multimedia data and it also have a convenient developing tool. using tm1300 we only need few chips to implement our video - phone system

    我們用philips的tm1300作為我們系統的主晶元，再配以必要的外圍器件來構成可視電話系統。之所以選擇tm1300 ，是因為它是一個高效率的dsp晶元，具有vliw指令，特別適合來進行多媒體處理。
  4. So, we must design multimedia application - oriented computer architecture to fit the data processing demand of video compressing programs, we analyzed the parallelism of two representative video compressing programs - opendivx and tml9, and drew a conclusion that it is effective to run video compressing application programs on the processor which uses parallel arithmetic units

    相對于視頻壓縮應用而言，普通計算機的處理能力大大落後于處理需求。因此，對于多媒體應用，必須採用并行的方法來解決，但是不能簡單地使用普通并行機，必須針對這部分應用的特點，採用并行的思想來設計面向多媒體應用的計算機體系結構。
  5. Then, chapter four describes the details of the implementation of video processing subsystem from processor unit, storage architecture unit, data i / o host - slave bus, data i / o interconnection unit four design aspects. in chapter five, host application programs and windows device driver design based on wdm are discussed

    第四章從處理器單元設計、存儲結構單元設計、數據i o主從總線設計，數據i o互連總線設計和系統控制中心單元設計五個方面分析視頻處理子系統的詳細設計。
