| 摘 要： | 详细分析了基于CS4281声卡的VOIP在VxWorks操作系统下的实现。对基于声卡的VOIP的原理作简要阐述,深入分析适用于VOIP的CS4281声卡的驱动程序、通信模块的结构和实现,描述了开发过程中遇到的主要问题及解决方法。该声卡驱动更多侧重PCI声卡驱动程序在VxWorks下实现的共性,包括必须的配置和步骤,这为其他声卡在Vx-Works下的驱动提供了一定的参考。VOIP的开发也为某些需要声音支持的嵌入式应用提供了支持。

| Abstract: | In this paper,detailed analysis of implementation of VOIP based on CS4281 soundcard in VxWorks is proposed.Firstly,theory of VOIP based on soundcard is introduced.Then,analysis of structure and implementation of soundcard driver and network communication module are given.At last,the questions and methods in development process are describered.The soundcard driver in this paper pay more attention on common characteristic of implementation of PCI soundcard driver in VxWorks,which include necessary configuration and steps.It provides some reference to another sound card driver in VxWorks.Development of VOIP support the embedded application with sound. |
