用dsp实现语音采集和传送，语音信号的输入：AIC23 通过其中的AD 转换采集输入的语音信号，每采集完一个信号后，将数据发送到DSP 的McBSP 接口上，DSP 可以读取到语音数据，每个数据为16 位无符号整数，左右通道各有一个数值。语音信号的输出：DSP 可以将语音数据通过McBSP 接口发送给AIC23，AIC23 的DA 器件将他们变成模拟信号输出。-
Acquisition and transmission of voice, voice signal input: using dsp AIC23 through which the AD conversion acquisition input voice signal from a signal of each collection, the data sent to the DSP s McBSP interface, the DSP can be read into the voice data,each value is the 16-bit unsigned integer, left and right channels each have a value. Voice signal output: DSP voice data sent by the McBSP interface to the AIC23, AIC23 the DA devices into analog signal output.
