PCM stream which has been bit blocked is sent into computer, buffered by a dual port static ram, then it's frame blocked roughly.

首先将接收到的PCM数据流进行位同步，然后经过一双口ram作为缓冲，直接送入微机进行实时帧同步码粗同步。

The use of multi-channel buffered serial port MCBSP is to achieve SPI bus (mode of) data collection, and the real-time data transmission and storage is achieved by the use of two DMA controllers.

利用多通道缓存串行口mcbsp实现SPI总线方式的数据采集，并采用两个DMA控制器实现了数据的实时传输和存储。
