摘要
嵌入式应用系统面临实现实时多任务时,多MCU构建的电路系统具有技术难度低、开发周期短等特点。文章介绍了串行总线传输、并行数据传送、数据共享等多MCU系统的构架方法。并举例说明在设计多MCU系统时应根据系统的实际要求,合理选取构架方法,完成MCU之间的协调,实现系统功能,满足实时性和并行性的要求。
This paper puts forward that the circuit system constructed by muhi-MCU owns good features such as lower technique difficulty and short design cycle.. It introduces mainly muhi-MCU application system constructing methods, including serial bus transmission, parallel data transfer, data sharing, and so on. It illustrates that when muhi-MCU application system is designed, reasonable constructing methods should be chosen according to actual system requiremens to make MCU work accordingly with each other, to realize system function, and so to satisfy requirements of real time character and being paralleled.
