摘要
针对μC/OS-Ⅲ系统存在启动需要延时、统计任务耗时过长等问题,以MPC555为平台对μC/OS-Ⅲ系统进行优化。采用Tick法解决μC/OS系统启动延时的问题,同时采用剔除任务堆栈统计的方法解决统计任务耗时过长的问题。使用Tick法后,μC/OS系统启动无延时,提高了统计任务效率,降低了CPU负荷,使优化后的系统可靠性更高。
Aiming at the problems of startup delay and long time consuming of statistical task inμC/OS-Ⅲsystem,theμC/OS-Ⅲsystem is optimized based on MPC555 platform.The Tick method is used to solve the startup delay ofμC/OS system,and the problem of long time consuming of statistical tasks is solved by eliminating task stack statistics.After using the Tick method,the startup time delay of theμC/OS system is solved,and the time consumption of the statistical task is reduced as well.After the optimization,the system is more reliable.
