We can take dsp to realize fast encryption algorithm because of its highly parallelism , application - specific hardware logic , and application - specific instructions . pci transaction and dsp processing of data can take place simultaneously for its dual - access ram ( daram ) and host port interface ( hpi ) . and , the time taken for interruption almost can be ignored because of deep buffer technology Dsp具有高度的并行結構、專用硬件邏輯以及許多專用指令,可以實現快速加密算法, dsp的雙訪問ram ( daram )和主機并行接口( hpi )可以實現數據pci傳送和dsp處理同時進行,另外采用了深度緩沖技術,使花在主機中斷上的時間幾乎可以忽略不計,所以基于dsp的計算機數據加密卡pcijmc2000獲得了較高的處理速度。
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 。 在實際的研制過程中,利用cpld的在系統可編程( isp )技術和基于vhdl語言的可編程邏輯器件設計技術實現了視頻數據采集卡的控制模塊。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轉換芯片。針對大容量數據采集,采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。
Subsequently , taking into consideration the characteristics of audio data over internet including delay , jitter , packet loss and etc . , we propose a series of methods for solving this above problems , such as pre - storage technology , buffer technology , dynamic adjustment of the voice - coding rate to the state of network and integrated media synchronization playing mechanism , and etc . in the end , simulation on 10 / 100m lan is made using the above methods , and the result of the experiment demonstrates the method has good performance and can improve the quality of the audio data transmission 其次本文還深入研究了語音數據在非實時的internet數據網上的傳輸特性,這些特性包括延時、延時抖動、數據包丟失等。在本文的設計方案中提出了針對這些問題的解決方法,包括預取機制、設置緩沖區技術、動態速率調節技術以及媒體綜合同步播放機制等。最后采用這些方法在10 100m局域網上做了仿真實驗,實驗結果表明本文提出的方法是有效的,在網絡狀況惡劣的情況下能夠改善語音播放質量。
