Embodiment Construction

[0028] The present invention and specific implementation methods will be further described in detail below in conjunction with the accompanying drawings.

[0029] The present invention is a multi-task management method based on an embedded system, and the specific implementation steps are as follows:

[0030] (1) Initialization of the embedded multi-task management system

[0031] The initialization process of the embedded multi-task management system is carried out after the hardware initialization is completed. The system initialization collects all task information and implements the task structure. The steps are:

[0032] 1) Prohibition of interrupt: close the hardware interrupt source to prevent the interrupt from being processed correctly during the initialization of the embedded multi-tasking management system.

[0033] 2) Initialize the clock interrupt task linked list: collect all the interrupt tasks defined by the system in the form of a linked list, and the unit of...

Abstract

The invention relates to a multi-task management method based on an embedded system, the method of the invention divides the limited duty of the embedded system into different task levels beforehand: most for a real-time interrupt level, next for a clock interrupt level, once more for a high priority duty inquiry level, finally for a low priority duty inquiry level, the higher the priority is, the performability is higher, the task can be guaranteed more to complete, the lower the priority is, the performability is lower, therefore the duty with high real-time request is arranged in a higher duty level, the duty with low backstage real-time is arranged in a lower duty level. The invention has the advantages of fully guaranteeing the real-time of executing partial task, saving the system resources, and having brief and clear task management.

Description

technical field [0001] The invention relates to a task scheduling and management method of an embedded system, in particular to a multi-task management method of a low-complexity embedded system based on clock interruption. Background technique [0002] In the new century, information technology with computer technology, communication technology and software technology as the core has achieved rapid development, and embedded computing and systems are widely used in various equipment and equipment. Embedded system is described as: "Application-centric, software and hardware can be tailored, special-purpose computer systems that meet the strict comprehensive requirements of application systems for function, reliability, cost, volume, power consumption, etc.", consisting of embedded hardware and Embedded software consists of two parts. Hardware is the support, and software is the soul. Almost all embedded products require embedded software to provide flexible, diverse and appl...
