    摘要： Provided are a multi-tasking method of performing a plurality of tasks according to priority of each of the plurality of tasks, and an embedded system therefor. It is determined whether a resource that is to be used by a current task is being used by another task, a priority of the current task is compared to a priority of the task that is using the resource according to a result of the determination, and according to a result of the comparison, the priority of the task that is using the resource is increased to a highest priority of priorities of all tasks trying to occupy a CPU. Accordingly, conventional problems in the BPI and IIP schemes can be solved.

    摘要： Provided are a load balancing method and a load balancing apparatus in a symmetric multi-processor system. The load balancing method includes selecting at least two processors based on a load between a plurality of processors, from among the plurality of processors, migrating a predetermined task stored in a run queue of a first processor to a migration queue of a second processor, and migrating the predetermined task stored in the migration queue of the second processor to a run queue of the second processor. Accordingly, a run queue of a processor is not blocked while migrating a task, an immediate response of the run queue is possible, and a waiting time of a scheduler is reduced. Consequently, the scheduler can speedily perform context switching, and thus performance of the entire operating system is improved.
