摘要
针对多通道音频信号处理的需要,以TI公司浮点DSP芯片TMS320C6727为核心,利用片上多通道音频串口MCASP与4路专业音频ADC/DAC芯片PCM4104/4204,实现了4通道数字音频处理平台,并详细介绍器件的配置过程。基于该平台,只需增加ADC/DAC的个数就可将通道数方便地扩展为16路。通过一个声学通道建模案例,验证了该平台的效能。
In order to meet the needs of multichannel audio processing,a 4-channel audio processing platform is designed based on TMS320C6727,multi-channel audio serial port,and four-channel professional audio ADC/DAC chips PCM4104/4204.The configure process is described in detail.Based on this platform,the number of channel can be easily expanded to 16 by simply increasing the number of ADC/DAC.The efficiency is tested and verified through an acoustic path modeling case.
