摘要
介绍了共享存储器模式的高速远程通信卡。为了做到与底层 80 31和 80 98控制监测模块高速远程通信 ,该卡采用了以 80 31单片机为核心 ,以共享存储器的方式与主 CPU交换数据的设计 ,这样设计的优点是波特率的误差小 ,通信可靠性高 ,数据通信不需占用
This paper introduces the principle designing highspeed serial communication card using share storage.It is based on chip microprocessor 8031 for highspeed communication with monitor module 8031 and 8098,and exchanges data with main CPU by method of share storage.Using this design,its strong point is that baud rate error is small,higher reliability in communication,no using time of main CPU.
