Embodiment Construction

[0028] The present invention provides a timely message processing method, which is applied to an embedded multitasking operating system, including:

[0029] When the task receives the message, it judges whether the currently received message needs to be processed in time. If it needs to be processed in time, the timer is started. When the timer interrupt occurs, the timer interrupt processing program is executed. The specific job that the message corresponds to.

[0030] The method of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0031] see figure 1 , is a flow chart of a method embodiment of the present invention, including the following specific steps:

[0032] Step S101, after the system is started, create a task in the system, and the system stores corresponding functions that pre-encapsulate the work content related to different types of messages of the task;

[0033] Step S102, the created task starts;

Abstract

This invention discloses a message timely process method applied in imbedded multi-task operation system, which comprises the following steps: when task receives information, judging current message needs timely process; if it needs timely process, then starting timer; when timer interval generates, starting timer interval process program; executing relative detail work in timer interval process program. This invention discloses a imbed multi-task operation system structure of this method.

Description

technical field [0001] The invention relates to an embedded multitasking operating system, in particular to a method for timely processing messages received by tasks in the embedded multitasking operating system. Background technique [0002] In many embedded operating systems, the system is a multi-task (or multi-process) system, and the scheduling method adopted is preemptive. The switching and execution operations between each task are based on the message mechanism. That is to say, when a task A receives a message, it parses the content of the message and starts to execute the specific operation corresponding to the message; when the execution of this message is completed, task A waits to receive the next message, and follows the received next The instruction content of the message executes the corresponding operation until task A receives and processes all the messages and ends the task. However, during the specific operation of task A executing the message, it may be...
