Problems solved by technology

At present, the existing task scheduling methods often emphasize real-time performance, but lack of in-depth analysis of how to schedule on multi-core, so efficient scheduling cannot be achieved; at the same time, because the existing scheduling methods require a relatively strict assumption, so in practice It is often very limited when using

Embodiment Construction

[0033] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, which are not intended to limit the protection scope thereof.

[0034] A method for realizing real-time task scheduling in a multi-core embedded system, the steps of the method are as follows figure 1 What not:

[0035] S10. Establish a real-time task set T including all tasks in the multi-core embedded system.

[0036] For all tasks in the multi-core embedded system, a task set T is established, T is composed of n tasks in the system, which can be expressed as:

[0037] T={T o , T 1 ,...,T n-1};

[0038] For example, for a multi-core embedded system with 15 tasks, its set T is:

[0039] T={T 0 , T 1 , T 2 , T 3 , T 4 , T s , T 6 , T 7 , T 8 , T 9 , T 10 , T 11 ,T 12 ,T 13,T 14};

[0040] For the task Ti(0_q<N) in T, establish an attribute set Ai for it, including the execution time length Ei and the completion time limit re...

Abstract

The invention discloses a real-time task scheduling implementation method of a multi-core embedded system. The method comprises the following steps of establishing a real-time task set, calculating a task dependency relation sequence, establishing a task sequence so as to complete a time limit requirement sequence, processing an initial dispatching task and establishing a dispatching sequence. According to the technical scheme, the real-time task scheduling implementation method of the multi-core embedded system is suitable for task real-time scheduling of the multi-core embedded system, a plurality of processor cores of a multi-core processor are fully utilized, the task processing speed in the multi-core embedded system is increased, and the real-time performance of a real-time task is also guaranteed.

Description

technical field [0001] The invention belongs to the technical field of multi-core embedded system task resource scheduling, and in particular relates to a method for realizing real-time task scheduling of a multi-core embedded system. Background technique [0002] With the continuous progress of semiconductor technology, the integration density of VLSI (Very Large-Scale Integrated, Very Large-Scale Integrated Circuit) is greatly increasing. The continuous improvement of integration on a single chip makes SoC (System on Chip, system on chip) technology developed and applied. SoC technology integrates all functional modules of a system into a single chip, so as to realize the integration of complete system functions on a single chip, and its processor core is also referred to as the core. [0003] What is integrated on the SoC chip is usually an IP (Intellectual Property, intellectual property) core. These reusable IP cores include embedded processors, memory modules, interf...
