| 摘 要： | 提出一种基于Motorola DSP56364的数字音效处理系统的设计方案。文中首先讨论数字音频系统设计需要注意的事项，接着分析DSP56364的ESAI接口通过I^2S协议与外部A／D、D／A进行无缝连接的问题，并给出系统的流程和硬件结构框图。最后以典型的回声音效算法为例，说明基于该系统平台的软件处理流程。实验表明在该系统平台上可以很好的运行多种音效处理算法。

| Abstract: | A design based on Motorola DSP56364is proposed for digital audio effects pro-cessing system.The article firstly makes a discussion on what we should pay attention in the dig-ital audio system design,secondly analyzes those problems that occur when ESAI interface of DSP56364is connected seamlessly with the peripheral A/D and D/A devices according to the I 2 S specification,and then gives the system flow and hardware architecture block diagram.As an example a typical ECHO algorithm is given to demonstrate the software processing flow at last.Experiments show that various audio effect algorithms can run well on this system platform. |
