基于SOPC的蓝牙-以太网语音网关的设计

Design of Bluetooth-Ethernet Voice Gateway Based on SOPC

基于先进的SOPC技术的系统设计具有极大的灵活性,广泛应用于各类电子设计中。本文提出的语音网关,将蓝牙作为短距离无线接入技术,支持多个蓝牙终端通过以太网交换分组语音数据。网关可以同时支持的蓝牙终端数目可以通过配置IIS控制器灵活地调整。文章系统地介绍了SOPC的开发流程,IIS控制器IP核,以及基于NiosII软核的设计方法。

Widely used in many electronic designs, system development based on advanced SOPC allows considerable flexibility. The voice gateway brought out in this paper uses Bluetooth for short distance wireless access and allows multiple Bluetooth terminals to switch packet voice via Ethernet. The number of Bluetooth terminals supported simultaneously by the gateway could be flexibly adjusted by configuring IIS controller. It first begins with the development procedure of SOPC, and then the design mechanism of IP core for IIS controller and software based on Nios Ⅱ CPU.
