| Abstract: | A sound source localization system based on TMS320C6713 and microphone array is introduced. The system uses DSP as its core controller and connects AD chip PCM4204 with McASP interface of TMS320C6713, which overcome the disadvantages of limited operational capability and slow speed of data processing, and satisfy the demand of sound source localization. The design of hardware and the idea of software are both introduced, the advantages of high speed of real-time processing, high precision and good reliability are proved. |
