| 摘 要： | 在语音设备的设计过程中,有一重要环节就是选择合适的模拟通道器件与DSP配合工作;在所完成的某小型便携式语音终端的硬件平台开发中,选取TMS320C5416用于语音编解码等复杂语音信号处理;而在众多可以与该DSP配合的AD、DA器件中,集A/D和D/A转换于一身的AD73322成为最好的选择;文中以实际设计案例给出了单片AD73322及多片AD73322级联(外部音频通道较多的场合)与TMS320C5416芯片配合使用的硬件连接方法和编程策略;对于类似的DSP+AD/DA硬件平台设计具有普遍的参考意义。

| Abstract: | It is important to select a proper analog device working with DSP when a studio set is being developed.In a potable studio set,TMS320C5416 was selected to process complicated arithmetic,and AD73322 is selected to work with the DSP.AD73322 features two16-bit A-D conversion channels and two 16-bit D-A conversion channels and Programmable Input/Output Sample Rates as well,which insured the performance of the set developed and the space of PCB was saved at the same time.Papers presented hardware connection meth... |
