摘要
提出了一种利用嵌入式微处理器设计的智能四串口通讯模块。主、从CPU协调控制信息传输,由从CPU负责串口的接收和发送,使主CPU的通讯任务占用很小的系统资源,并使用CPLD技术及高速串口集成芯片。说明该串口通讯扩展模块具有智能可编程、实时并行的特点,能够满足实际工业控制对象的的需求。
A method of designing 4 serial port intelligence communication module with the embedded microprocessor is put forward. Master CPU and slave CPU are used to control information transmission together. Slave CPU takes charge of reception and sending, so that master CPU can assign few resources for communication task. CPLD technology and high speed serial port chip are adopted in this module, it can be concluded that the serial port communication extended module be provided with intelligence programmed and real time parallel peculiarity and it can achieve the requirements of the actual industrial controlled object.
