| Abstract: | 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. |
