MULTI-CORE PROCESSOR SYSTEMS AND METHODS FOR ASSIGNING TASKS IN A MULTI-CORE PROCESSOR SYSTEM

摘要

A multi-core processor system and method are provided. The multi-core processor system includes a plurality of processor cores and a task scheduler. The processor cores perform a plurality of tasks, wherein each of the tasks is in a respective one of a plurality of scheduling classes. The task scheduler obtains first task assignment information about tasks which are in a first scheduling class from the scheduling classes and assigned to the processor cores, obtains second task assignment information about tasks in one or more other scheduling classes and assigned to the processor cores, and refers to the first task assignment information and the second task assignment information to assign a runnable task in the first scheduling class to one of the processor cores. Prior to the assigning the runnable task, the runnable task has been assigned to one of the processor cores.
