单片机多任务架构软件的限时服务设计

Application of Time-Limited Service in Multi-Task Architecture of MCU

介绍了单片机软件中的多任务机制,详细说明了在这种机制下的限时服务原理及设计方法,能够防止和解决因任务交叉重叠而导致运行状态错误,亦可应用在顺序流程的程序结构中,提高系统的冗余度和可靠性.

Multi-task architecture of MCU software is introduced, based on which, Principle of time-limited service is advanced firstly, including its design. This way can be applied in not only Multi-task architecture to prevent MCUs duty from being overlapped which leads to fail, but also sequence operation flowchart to improve systems reliability.
