Method for realizing process support, device and multithreading system

Abstract

The invention provides a method for realizing process support, a device and a multithreading system. The method comprises the following steps of: establishing process; establishing an agent thread corresponding to the process; and when the agent thread obtains processor resource allocated by a scheduler, allocating the processor resource to the process corresponding to the agent thread. The method can effectively realize the support to the process under the condition that any modification is not needed to the operating system of the original multithreading system and all the software modules.

Description

technical field [0001] The invention relates to a method, device and multi-thread system for realizing process support, and belongs to the technical field of data communication. Background technique [0002] Embedded system is a special computer system that is completely embedded in the controlled device and designed for specific applications. The system is mainly suitable for applications with strict requirements on function, reliability, cost, volume, and power consumption. [0003] With the development of embedded systems, the complexity of embedded software is getting higher and higher, so the embedded operating system is introduced in the development of embedded system software. Embedded operating system is an operating system software that supports embedded system applications. It can effectively manage more and more complex system resources and provide a multi-task operating environment for embedded software modules, making program development easier and easier to ma...

Problems solved by technology

However, for some original systems that have been developed and used for a long time, due to their large scale, long development cycle, and after they are put into use, they are always in a long-term and continuous maintenance process, and the software code is constantly introducing new technologies. Modifications

In such a long process, there may be a large number of codes of the original system that cannot be updated due to personnel changes of developers, or lack of documentation due to lack of modern software engineering methods in the development and maintenance of the original system. of software developers fully understand

In this case, the risk of modifying the original software code is extremely high, and more software faults may be introduced during the modification process, reducing the quality of the software and the reliability of the system.
