Design of the Interface between DSP and DPPC2006

This paper presents the characteristics of digital audio amplifier chip DPPC2006 and the DSP chip TMS320VC5409.The digital audio interface between DSP and DPPC2006 is designed according to requirements of the digital audio processing system and IIS,and in this system the universal DSP produced by TI Corporation is designed as a digital sound-field processor,and then,the setting program of McBSP registers about DSP is listed.The design implements the application of DSP in the digital audio processing system,which enhances the flexibility of the system,and is verified by experiment with high reliability.
