A task execution method and multi-core processor-based controller

Abstract

The invention discloses a task execution method applied to a controller based on a multi-core processor. The controller includes the multi-core processor; the multi-core processor includes a main coreand a processing core, a real-time operating system is installed on the main core, and a non-real-time operating system is installed on the processing core; the main core executes interrupt events ortasks high in real-time performance; the processing core executes interrupt events or tasks low in real-time performance; when the main core executes an operation task, data interaction processing isconducted between the main core and the processing core through a shared memory module; the operation task is an interrupt event or task which requires computing processing. The main core is in datacommunication with the processing core through shared memories so that data interaction can be achieved among complex tasks which require various kinds of real-time processing at a faster speed. The invention also discloses the controller with the advantages.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a multi-core processor-based controller and method. Background technique [0002] With the development of science and technology, the shape of the machine is also changing. The attention of engineers has shifted from how to make the machine run in a fixed manner to how to make the machine handle problems in real time and operate according to the processing results. With a preliminary thinking form, it also possesses certain characteristics of humans, so machines that can "think" are called robots. With the development of electronic technology, the processing speed of robots is getting faster and faster. From handling simple problems to being able to handle complex problems, robots are used more and more widely. The application fields of robots are constantly expanding, and there are different requirements for the performance and execution efficiency of robots. It re...

Problems solved by technology

However, the Linux system is a soft real-time system. Even with real-time patches, it still cannot meet some low-latency and high-certainty application scenarios.

[0005] The above schemes cannot meet the requirements well in the face of different real-time tasks, so for those skilled in the art, how to make the robot better handle different real-time tasks is crucial
