基于單DSP的VoIP模擬電話適配器研究與實(shí)現(xiàn)

基于單DSP的VoIP模擬電話適配器研究與實(shí)現(xiàn):提出和實(shí)現(xiàn)了一種新穎的基于單個(gè)通用數(shù)字信號(hào)處理器(DSP)的VoIP模擬電話適配器方案。DSP的I/O和存儲(chǔ)資源非常有限，通常適于運(yùn)算密集型應(yīng)用，不適宜控制密集型應(yīng)用[5]。該系統(tǒng)高效利用單DSP的I/O和片內(nèi)外存儲(chǔ)器資源，采用μC/OS-II嵌入式實(shí)時(shí)操作系統(tǒng)，支持SIP和TCP-UDP/IP協(xié)議，通過(guò)LAN或者寬帶接入，使普通電話機(jī)成為Internet終端，實(shí)現(xiàn)IP電話。該系統(tǒng)軟硬件結(jié)構(gòu)緊湊高效，運(yùn)行穩(wěn)定，成本低，具有廣闊的應(yīng)用前景。關(guān)鍵詞：模擬電話適配器；IP電話；數(shù)字信號(hào)處理器；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

In C Algorithms for Real-Time DSP, author Paul M. Embree presents a complete guide to digital signal

In C Algorithms for Real-Time DSP, author Paul M. Embree presents a complete guide to digital signal processing techniques in the C programming language. This book is structured in such a way that it will be most useful to the engineer who is familiar with DSP and the C language, but who is not necessarily an expert in both. All of the example programs in this book have been tested using standard C compilers in the UNIX and MS-DOS programming environments. In addition, the examples have been compiled using the real-time programing tools of specific real-time embedded DSP microprocessors (Analog Devices ADSP-21020 and ADSP-21062 Texas Instruments TMS320C30 and TMS320C40 and AT&T DSP32C) and then tested with real-time hardware using real-world signals.

uc/os-ii for 8051 This package provides the sources required to use the uC/OS-II v2.00 real time kernel on the 8051 processor. To use this package you will need the TASKING C Compiler toolset v6.0r1 or higher. For info on TASKING products you can contact our Web-site at: http://www.tasking.com Unzip the zipfile in the root of the drive where you also installed the uC/OS-II general sources. The following directories will be added: \SOFTWARE\UCOS-II\8051 This directory contains the microprocessor specific source code \SOFTWARE\UCOS-II\ex1_8051r This directory contains the project files for the first example \SOFTWARE\UCOS-II\ex2_8051r This directory contains the project files for the second example

This the first release of a free TCP/IP/PPP protocol stack for the uC/OS Real-Time Operating System.

This the first release of a free TCP/IP/PPP protocol stack for the uC/OS Real-Time Operating System. As a first release it s still rather rough and very much larger than desired however it is working well in an embedded product and therefore may be useful to others. Much of the code is ported from public sources including BDS Lite and KA9Q (and its derivatives) and carries copyright notices from those sources. Essentially TCP is based on KA9Q but with ideas from BSD, IP is a simple implementation supporting BSD structures, ICMP is ported from BSD, and PPP is ported from the BSD version of the distribution common to BSD, Linux, and many other systems

DSP音頻處理示例The benefits of real-time analysis provided by DSP/BIOS are often required in programs that were engineered without it. When the program is not built from the ground up using the DSP/BIOS kernel and real-time analysis features, the lack of familiarity prevents engineers from reaping the benefits of this very powerful tool set, especially in the final stage of development when real-time analysis is needed most. This application note provides an example of the necessary steps required to utilize DSP/BIOS features in order to bring these solutions to bear in an existing application.
