摘要
针对嵌入式实时操作系统在多周期任务及多非周期任务的场景下,既要保证周期任务在截止期内能够及时响应,又要保证非周期任务能够即时处理。目前的主流调度算法存在局限性。零星服务器调度算法作为一种指定执行预算及补充周期的非周期任务的调度算法,可以较好的满足即时响应非周期任务,同时保证系统内其他周期任务的响应。本文简述了在RTEMS嵌入式实时操作系统下实现零星服务器调度的方法,并对该算法进行测试,看是否达到了预期要求。
For embedded real-time operating system in periodic tasks and aperiodic tasks,it is necessary to ensure that the periodic tasks is withing the deadline,also the aperiodic tasks should be handled immediately?However the mainstream schedulers have limitation?The sporadic server scheduling algorithm can provide a fast response not only the periodic tasks but aperiodic tasks.This article briefly introduces a method and Realization of Sporadic Server Scheduling on RTEMS Embedded Real-time Operating System,as well as test and verify this algorithm?
