摘要:

介绍了基于TMS320C6713的信号采集处理系统。该系统以TMS320C6713作为核心控制器,通过多通道音频串行口(McASP)与A/D芯片PCM4204连接。系统充分利用McASP接口多通道的特点,设计了16通道麦克风阵列采集处理平台,并通过外扩USB芯片与PC主机端进行数据传输,方便用户在PC端进行数据处理。该系统采样数据量大、同步性强、精确度高、传输速率快、可靠性好,方便为各种麦克风阵列应用提供原始数据。

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
