摘要
介绍利用VHDL(Very-High-Speed Integrated Circuit Hardware Description Language)硬件编程语言开发FPGA(Field Programmable Gate Array)来实现PBX(Private Branch Exchange)端口语音信号的收发处理。重点介绍PBX端口语音信号的发送、接收和收发部分的互连测试。经过软件仿真分析及FPGA硬件测试,证明系统运行良好。
This paper mainly introduces how to realizing the receiving and sending of speech signal in the Private Branch Exchange （PBX） port by Field Programmable Gate Array （FPGA）, which is developed by the hardware program language （VHDL）. And it focus on the following parts： the outlet and take-over of the section of PBX, and the connection between the outlet and take-over section. The results of the simulation analysis of the software and the debugging of the hardware show the established system run well.
