摘要
计算机技术和通讯技术的飞速发展为现代大型、复杂系统的设计提供了新的解决方案 ,同时也提出了新的挑战。系统中各微控制器之间通过串口进行信息交换是一种成熟且普遍采用的通讯方式。传统的多机串行通讯实时性、可靠性差 ;对此 ,提出了一种能够大大提高系统通讯实时性和可靠性串口扩展的新方案。
The development of the computer and Tele-communication techniques provide new solutions for nowadays systems design.Serial communication is one of the most mature and wide spreaded methods in use.This paper presents a novel solution that can highly enhance the commumication performance.Principles and technical details have been discussed thoroughly in the paper,a states-shift charts is also provided.
