MQX任务优先级的设置与对中断影响的研究
RESEARCH ON MQX TASK PRIORITY SETTING AND ITS IMPACT ON INTERRUPT
摘要
Abstract
The task priority of MQX embedded real-time operating system ( RTOS) has the impact on real-time performace of interrupt system, memory usage, speed of task scheduling, etc.For these problems, we thoroughly study the MQX tasks and interrupt priority level setting, the mechanism of the influence of task priority on interrupt, the relation between task priority and interrupt priority, and analyse the relations of task priority with memory usage, inter-task and task scheduling.Moreover, we verify these relations by engineering test.Finally, we present the basic programming essentials of MQX embedded engineering task priority setting.These provide good suggestions for reasonably setting tasks priority and reducing memory loss, improving the speed of task scheduling and the systems real-time reliability and integrality of the information processing.关键词
