Design of Audio Signal Processing System Based on DSP

摘要：

This paper develops an audio signal processing system based on TMS320DM643 and TLV320AIC23. Firstly, the basic characteristics and properties of TLV320AIC23 and TMS320DM643 are introduced. Secondly, the whole hardware designation is proposed. Also the interface circuit of TLV320AIC23 and TMS320DM643 is presented in detail. Finally, the software implementing course through the Infinite Impulse Response (IIR) Filters processing to the audio signal is shown. The algorithm which is realized in the DSP has short running time, obvious regularity and the virtue of being practical. The results show that the system has good purpose and adaptability. It can be used and improved easily.
