提出一个基于TMS320VC5402的音频信号采集与处理系统。介绍了该系统的总体方案和硬软件设计。讨论了模/数(A/D)和数/模(D/A)转换电路的设计方法以及如何利用TMS320VC5402的多通道缓冲同步串口(McBSP)和PCM1800及PCM1744芯片接口来实现音频信号的采集和输出。实验证明:所设计的基于DSP的硬件和软件系统是一个很好的音频信号采集与处理系统。
A TMS320VC5402-based audio signal acquisition and processing system is proposed. Introduced the system overall plan and hardware and software design. This paper discusses how to design A / D and D / A converter circuit and how to use TMS320VC5402 multi-channel buffered synchronous serial interface (McBSP) and PCM1800 and PCM1744 chip interface to realize the audio signal acquisition and Output. Experiments show that: the design of DSP-based hardware and software system is a good audio signal acquisition and processing system.
