上面是关于SPORT中的chained DMA的Chain Pointer Register的使用说明。但是在ADI提供例程中却没有将地址分离开来就赋值入寄存器了,具体见下面例程[table][tr

困惑,文档中写的跟例程中不一样,所以不知道各位有没有配置chained DMA的经验讨论一下。其实例程也不稳定,有时会出不来声音,或者是声音失真,出现噪音等问题。

adsp-21364 EZKit的example 里有个 block-based talk thru project。 里面用到了以三个buffer(缓冲器?)组成的circular buffer (环形缓冲区)和 DMA chaining(链式DMA)。 三个buffer分别用来存ADC进来的数据, 处理中的数据, 和输出到DAC的数据。 而和以上的project不同的是, 我被要求只能用单个buffer完成talk-thru(麦克风的输入直接送到音响的输出)。并且要运用到链式DMA。教授大体的意思是有两个pointer指在buffer上, 一个是输入数据,一个是输出数据。 DMA counter降到0后pointer分别各自移动。 不好意思, 阐述的可能有点混乱, 也刚接触这块板, 所以不懂的很多。 可以有人解释一下这个链式DMA单buffer的talk-thru怎么运作吗? 万分感谢
