| Abstract: | The design method of a digital voice processing card based on high speed DSPs is described. We use six chips of TMS320VC549 which are high speed 16 bit fixed point DSPs of TI in the design of the card, and every card can process 16 channel voice signal. High performance DSPs make the card possible to accurately process large amount of speech data in time. The card makes up the core of IP phone. |
