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具有高度的并行结构、专用硬件逻辑以及许多专用指令,可以实现快速加密算法, dsp的双访问ram ( daram )和主机并行接口( hpi )可以实现数据pci传送和dsp处理同时进行,另外采用了深度缓冲技术,使花在主机中断上的时间几乎可以忽略不计,所以基于dsp的计算机数据加密卡pcijmc2000获得了较高的处理速度。
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 。 在实际的研制过程中,利用cpld的在系统可编程( isp )技术和基于vhdl语言的可编程逻辑器件设计技术实现了视频数据采集卡的控制模块。在视频的a / d转换模块,用汇编程序模拟i2c总线对初始化a / d转换芯片。针对大容量数据采集,采用了双缓冲技术解决wndows操作系统下难以申请到大容童连续内存的间题。
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 其次本文还深入研究了语音数据在非实时的internet数据网上的传输特性,这些特性包括延时、延时抖动、数据包丢失等。在本文的设计方案中提出了针对这些问题的解决方法,包括预取机制、设置缓冲区技术、动态速率调节技术以及媒体综合同步播放机制等。最后采用这些方法在10 100m局域网上做了仿真实验,实验结果表明本文提出的方法是有效的,在网络状况恶劣的情况下能够改善语音播放质量。
