基于嵌入式系统的以太网电话机设计与实现

基于FPGA嵌入式系统的设计思路，对以太网电话机的设计与实现进行了研究。应用SOPC技术和嵌入式软件，能够以低成本制作出实用的以太网电话机。以太网电话机是P2P（PeertoPeer）计算机语音技术的嵌入式版本，把以太网电话机接人以太网后，不需要再在网络上增添任何其它专用设备，就可以按照传统电话机的使用方法拨号呼叫在同一网络上的另一台以太网电话机并进行双向通话。以太网电话机结构紧凑、性能可靠、使用方便，不仅可用于网内的语音交换，还可为网络语音调度技术提供一种新的思路。

Design and Realization of Embedded System Based Ethernet Telephone Set

Based on the idea of FPGA embedded system the design and realization of the Ethernet telephone set is researched. With the SOPC technology and embedded software a low cost production of the Ethernet telephone set for practical use has been made. The Ethernet telephone set is an embedded version of peer to peer computer voice technology. Without adding any other special equipment, the Ethernet telephone set connected to the Ethernet network can dial up and talk with another Ethemet telephone set in the same network as conventional telephone sets. The Ethernet telephone set has compact structure, reliable performance and is convenient for use, it is not only used for voice switching in network, but also provides a new approach for network voice dispatching technology.
