  • 基于单DSP的VoIP模拟电话适配器研究与实现

    基于单DSP的VoIP模拟电话适配器研究与实现:提出和实现了一种新颖的基于单个通用数字信号处理器(DSP)的VoIP模拟电话适配器方案。DSP的I/O和存储资源非常有限,通常适于运算密集型应用,不适宜控制密集型应用[5]。该系统高效利用单DSP的I/O和片内外存储器资源,采用μC/OS-II嵌入式实时操作系统,支持SIP和TCP-UDP/IP协议,通过LAN或者宽带接入,使普通电话机成为Internet终端,实现IP电话。该系统软硬件结构紧凑高效,运行稳定,成本低,具有广阔的应用前景。关键词:模拟电话适配器;IP电话;数字信号处理器;μC/OS-II 【Abstract】This paper presents a VoIP ATA solution based on a single digital signal processor (DSP). DSPs are suitable for arithmetic-intensiveapplication and unsuitable for control-intensive application because of the limitation of I/O and memory resources. This solution is based on a 16-bitfixed-point DSP and μC/OS-II embedded real-time operating system. It makes good use of the limited resources, supports SIP and TCP-UDP/IPprotocol. It can connect the analog telephone to Internet and realize the VoIP application. This system has a great future for its high efficiency andlow cost.【Key words】Analog telephone adapter (ATA); Voice over Internet protocol (VoIP); Digital signal processor (DSP); μC/OS-II Research and Implementation of VoIPATA Based on Single DSP

    JBoss, one of the leading java Open Source groups, integrates and develops these services for a full J2EE-based implementation. JBoss provides JBossServer, the basic EJB container, and Java Manage Preface 18 great Events of the Twentieth Centuryment Extension (JMX) infrastructure. It also provides JBossMQ, for JMS messaging, JBossTX, for JTA/JTS transactions, JBossCMP for CMP persistence, JBossSX for JAAS based security, and JBossCX for JCA connectivity. Support for web components, such as servlets and JSP pages, is providedby an abstract integration layer. Implementations of the integration service are provided for third party servlet engines like Tomcat and Jetty. JBoss enables you to mix and match these components through JMX by replacing any component you want with a JMX compliant implementation for the same APIs.

    SDL Library Documentation. The SDL library is designed to make it easy to write games that run on Linux, *BSD, MacOS, Win32 and BeOS using the various native high-performance media interfaces, (for video, audio, etc) and presenting a single source-code level API to your application. SDL is a fairly low level API, but using it, completely portable applications can be written with a great deal of flexibility.
