基于DSP和FPGA的高速实时语音数据处理的设计与实现

Design and Implementation of High-speed Real-Time Speech Data Processing Based on DSP and FPGA

文中介绍了应用于电信网监测管理系统中一种高速数据采集硬件的设计与实现,该接口板主要采用DSP和FPGA来完成如下功能,能对接收的信道内容进行初步判别,如语音、传真、VBD等业务;能利用对应的软件模块实现对某一种接收内容的初步处理;能实时接收两路155M SDH信号并转为以太网数据格式,传送给后端平台作进一步处理。本系统对目前电信网流量监控系统的研究,具有非常重要的现实意义和应用前景。

This paper describes a kind of high-speed hardware design and implementation applied in telecommunication network management system. DSP and FPGA are adopted in the interface board for achieving some functions as follows： preliminary estimation on the content received from channel, including voice, faxes, VBD service; preliminary process on received content by using corresponding software model; realtime receiving and converting two-way 155M voice data to ethernet data format, and tranfering to back end platform for further processing. This system has great practical significance and application prospect for the research of telecommunication network flow supervisiso and control system.
