摘要
VOIP技术的蓬勃发展,使IP电话越来越受重视。文中介绍了一种通过DSP与ARM设计IP网络电话的方案。给出了DSP与ARM分工,介绍了两者之间通信的硬件设计方法,以及G.729压缩算法在DSP上的实现方法、SIP协议、TCP/IP协议的实现方法。
The vigorous development of VOIP draws increasing attention to IP phone. This article puts forward an IP phone design scheme using DSP and ARM. The respective duties of DSP and ARM, and the hard- ware design of communication between ARM and DSP are presented. Also introduced are G. 729 compression algorithm and its realization on DSP, SIP protocol, TCP/IP protocol and its realization.
