多数据流采集处理中的软硬件接口设计——基于TMS320VC5402与TCL320AD50C之间的通信

Interface design in communication between TMS320VC5402 and TLC320AD50Cs Based on multi-data stream sampling and processing

主要介绍了TMS320VC5402(VC5402)与两片TCL320AD50C(AD50C)之间通信的软硬件接口设计,这种工作方式实现了两个数据流同时采集并以时分复用(TDM)的方式送入处理器中进行处理.其中一片AD50C工作在主机模式下,另一个工作在从机模式下.两转换器件输出的数据帧分别在各自的帧同步周期内送入处理器进行处理.

A new interface design in the communication between VC5402 and two AD50Cs is introduced. This mode makes it more convenient to sample two different kinds of data streams simultaneously and feed them into processor ( VC5402) in TDM mode. One of AD50Cs works in the master mode, the other in slave mode. Each AD50C delivers its sampling signals to the processor in its own circle.
