Packaging method based on VxWorks real-time operating system

Abstract

The invention discloses a packaging method based on a VxWorks real-time operating system. The packaging method comprises the following steps: firstly, designing a message queue management structural body; then defining a global array management message, wherein an array element is a message queue management structural body; in a message queue sending function, applying a pointer variable for a message queue management structural body, so that a space is applied for message content to be transmitted; assigning a value to a pointer variable of the message queue management structural body; sending out the message queue management structural body through an operation system message queue sending function, and releasing the space of a pointer variable of the message queue management structural body; and associating the sending thread and the receiving thread of the message, obtaining the received message queue management structural body in the receiving thread, analyzing and processing the content of the message queue management structural body, and completing packaging. According to the method, the task and the message queue of the real-time operating system are further packaged, and the packaged framework is directly called subsequently for development, so that the efficiency is improved, and the safety of the operating system is ensured.

Description

technical field [0001] The invention belongs to the field of computer operating systems, and relates to a packaging method based on a VxWorks real-time operating system. Background technique [0002] A real-time operating system is an operating system based on task priority. Tasks and message queues are two core features of real-time operating systems. Data transmission between tasks is usually completed using operating system message queues, and the two are usually closely combined. [0003] The real-time operating system is an operating system based on task priority. During the operation of the system, message transmission between tasks is often required, and the length of the message is generally not fixed. The traditional method is to create the message queue message The length value is set to be very large. In addition, apply for a large enough array variable to temporarily store the message to be sent, or define message queues of different lengths in different tasks, a...

AI Technical Summary

Problems solved by technology

Disadvantages of the traditional design method: the waste of memory space is relatively large, and the efficiency of message transmission between tasks is relatively low. When multiple types of data are transmitted between two tasks, the content of the message type needs to be added to the data content, which is not conducive to Guarantees the integrity of the entire message

, at the same time, when the types of messages received increase, the processing efficiency of the processing functions decreases with the increase of message processing functions
