Abstract

The present invention discloses a task scheduling method for a heterogeneous multi-core processor system, wherein the heterogeneous multi-core processor system includes at least one first processor core with a first computing capability and at least one first processor core with a second computing capability Two processor cores, the first computing capability is higher than the second computing capability, and the task scheduling method includes: determining at least one of the tasks belonging to the first priority task group according to the task priorities of the tasks of the heterogeneous multi-core processor system a first task, wherein the task priority of each first task belonging to the first priority task group is not lower than the task priority of other tasks, and the other tasks do not belong to the first priority task group; and assigning the at least A first task is assigned to at least one run queue of the at least one first processor core. The task scheduling method for a heterogeneous multi-core processor system can reasonably arrange tasks of different processor cores.

Description

[0001] cross reference

[0002] This application claims priority to US Provisional Patent Application Serial No. 61 / 897,362, filed October 30, 2013. The aforementioned US Provisional Patent Application is hereby incorporated by reference. technical field

[0003] The invention relates to a task scheduling method. In particular, the present invention relates to a task scheduling method for scheduling tasks (such as real-time tasks) based on computing capabilities of different processors in a heterogeneous multi-core processor system. Background technique

[0004] Nowadays, the use of multi-core systems in electronic devices is becoming more and more popular due to the increasing demand for computing power. Due to the emergence of multi-core systems, the operating system (OS) of the multi-core system needs to determine the task scheduling of different processor cores to maintain better load balance and / or higher system resource utilization. For a heterogeneous multi-core s...
