摘要
介绍了基于双缓冲与环形缓冲技术的串行驱动设计,给出使用双缓冲与环形缓冲区实现高速发送或接收数据的设计思路及实现方法,运用此方法编写异步串行板WDM模式驱动。
This paper present the design of the ring-buffer for asynchronous serial port driver based on WDM mode,and also introduces the technology of double-buffer and ring-buffer.The technologies is used for asynchronous serial port device.It not only meets the requirements of serial port communication,but also ensures the correctness of data packet transmission.
