利用CPLD实现高速异步串行通信的方法,主要适用于必须使用高速异步串行通信,而对误码率要求又不是很高的应用环境,如基于RS485协议的共线语音通信系统。
The method of realizing high speed asynchronous serial communication by using CPLD is mainly applicable to an application environment that must use high speed asynchronous serial communication but does not require high bit error rate, such as a collinear voice communication system based on RS485 protocol.
