本实验讲述了与多通道缓冲串口（McBSP）相关的寄存器的含义，并通过在DSP系统中实现音频扩放系统的自动增益控制（AGC）算法这个例子了解多通道缓冲串口的应用。-about this experiment with multi-channel buffer serial port (McBSP) related to the meaning of the Register, and through the DSP Audio System to expand the system up Auto

该算法实现的自动增益控制，使随输入信号电平变化而引起的输出信号电平变化少。 在工程中很常用-The algorithm of the automatic gain control, so that with the input signal level changes caused by the output signal level changes less. Very common in engineering
