一种基于FPGA的VoWLAN终端研究

Research on VoWLAN Terminal Based on FPGA

在分析现有网络电话终端实现方式的基础上,提出了一种基于现场可编程门阵列(FPGA)且具有无线保真(Wi-Fi)功能的无线网络电话终端(VoWLAN终端,基于无线局域网的语音通信终端)的设计方案。主要研究内容包括设计Wi-Fi通信模块,利用可编程片上系统(SOPC)技术在FPGA上移植OR1200软核处理器,将嵌入式Linux操作系统移植到OR1200软核处理器上,最后设计出VoIP应用软件。

In this paper, the design based on Field Programmable Gate Array （FPGA） of wireless IP phone which can work in Wireless Fidelity （Wi-Fi） environment is proposed. The research includes designing Wi-Fi module, transplanting oRi200 soft core processor in FPGA using System-on-a-Programmable-Chip （SOPC） technology, transplanting embedded Linux operating system on OR1200, and finally designing the VolP application software.
