摘要
简要介绍了语音编解码芯片TLV320AIC23,提出了一种基于FPGA和TLV320AIC23的光纤语音传输系统的设计方案。在QuartusⅡ 7.2开发环境下,采用自顶向下利用原理图与VerilogHDL语言相结合的方式,用Altera公司的EP2C35F672C8芯片实现仿真。既可用于光纤通信实验教学,也可作为光纤语音传输系统的试验平台,具有实际应用价值。
This paper briefly introduces the voice codec chip TLV320AIC23,then a design of optical speech transmission system based on TLV320AIC23 and FPGA was proposed. The simulation was achieved through the Verilog Hardware Discription Language and useing schematic in top-down's way in EP2C35F672C8 chip in the development environment of QuartuslI 7.2. The design can be used in teaching optical fiber communication experiment and voice transmission system as a fiber-optic test platform,which has practical application value.
