CPLD控制的AES3数据采集系统

Collection of AES3 Data Using CPLD

AES3或其他串行格式的数字音频信号一般被直接送往发声设备播放,无须存储,然而在一些特殊的应用场合,必须对接收到的数字音频数据先进行存储,分析,并作相应的处理。有一种合适的硬件电路设计方案就是利用CPLD器件对串行数据进行收集,再以并行的方式存放于存储设备当中,并通过PCI总线的方式与计算机通信,以便计算机对接收到的数据进行分析和处理。

In common situation, the digital audio signal in AES3 or other serial format is just transmitted to audio equipment to play. There is no need to store the incomming serial data. But in some special case, it has to receive the data, store and analysize it, then make corresponding processing. There is a suitable solution of the hardware design. It takes advantage of the CPLD. The CPLD collects the incomming serial data and store the data into the storage device in parallel format. PCI bus is used by the system to communicate with personal computer system . So, the received data can be analysized and processed on the computer.
