摘要
为在保证操作系统运行精度的前提条件下实现多项任务同时运行,引入Cortex-M4内核开展对多任务实时操作系统的设计研究。通过主/辅控制器选型、电源设计等硬件设计和基于Cortex-M4内核的任务堆栈检测与状态转换、多任务调度与操作中断控制等软件设计,提出一种全新的操作系统。通过对比实验的方式,证明了将新的操作系统应用到真实环境中可以有效提高系统操作精度,并实现多项操作任务的同时进行。
In order to realize the simultaneous operation of multiple tasks under the premise of ensuring the operating accuracy of the operating system, the Cortex-M4 core was introduced to carry out the design and research of the multi-task real-time operating system.Through hardware design such as main/auxiliary controller selection, power supply design, and software design based on Cortex-M4 corebased task stack detection and state conversion, multi-task scheduling and operation interrupt control, a new operating system is proposed.Through comparative experiments, it is proved that applying the new operating system to the real environment can effectively improve the accuracy of the system operation and realize the simultaneous execution of multiple operation tasks.
