摘　　要：介绍了专业数字音频功放芯片DPPC2006和DSP TMS320VC5409芯片的主要特点。数字音频处理系统使用了TI公司的通用DSP作为声场处理器,根据系统和IIS数字音频格式的要求,设计了DSP与DPPC2006的数字音频接口电路,并给出了DSP的McBSP串口软件设置程序。该设计实现了DSP在数字音频系统中的应用,增强了系统的灵活性,并经实验验证了该接口电路的可靠性。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.
