DSP控制的两路音频信号实时采集电路的设计与实现
A Design and Implementation of Two-way Sound Signal Real-time Sampling System Controlled by DSP
【摘要】 利用两片A/D-D/A转换芯片TLV320AIC10以主从控制方式组成两路实时采样电路,采样结果经DSP芯片TMS320C5402的多通道缓冲串口0送入DSP中进行处理,实现了两路音频信号实时采样系统的硬件电路设计.采用C语言和汇编语言混合编程的方法,实现对该系统的软件程序设计.
【Abstract】 With two TLV320AIC10 chips connected in master/slave mode for sampling device and one DSP chip TMS320C5402 which receives the sampled data through McBSP0,the hardwire connection of the two-way real-time sampling system for sound signals is accomplished.The software program design of the system is completed by using assembly language in conjunction with C code.
