Abstract:

A signal collecting and processing system based on TMS320C6713 is introduced in the paper.The system uses TMS320C6713 as the core controller,connecting with PCM4204 through McASP of the controller.The system can take the full advantage of multiple thoroughfares,design the collecting and processing platform of the microphone array with 16 thoroughfares,and realize data transmission via the external USB chip,facilitating data processing with PC.Due to large quantity of sampling data,better synchronicity,high precision,high-speed data transmission as well as fine reliability,this system can offer a more efficient original data to all kinds of the microphone array application.

Key words: data collection;microphone array;McASP
