Digital voice processing system based on high-speed multi-DSP
Chen Hucheng, Qi An, Yanfang Wang, Chen Jiaqin · 2002
In this article, we introduce the design of the digital voice processing system based on multiple high-speed DSP chips. This system mainly consists of the digital voice processing module and route protocol processing module. We use six TMS320VC549 high speed 16-bit fixed-point DSP chips in the design of the digital voice processing module. Every module can process 16-channel voice signals. High performance DSP ships make it possible to accurately process a large amount of speech data at a time, forming the basis of the IP phone.
