Embodiment Construction

[0023] method embodiment

[0024] In this embodiment, a message queue management method is provided. In order to solve the problem that the ability of the system to process messages is reduced due to the failure of sending messages due to the full message queue in the embedded system.

[0025] Such as figure 1 As shown, the message queue management method according to this embodiment includes: step S102, setting one or more thresholds for the number of messages in the message queue; step S104, adjusting the priority of the message receiving task for receiving messages in the message queue according to the threshold .

[0026] In the case of setting only one threshold, the process of adjusting the priority of the message receiving task is as follows: when the number of messages in the message queue is greater than the threshold, the priority of the message receiving task is increased according to predetermined rules; or the priority of the message receiving task in the messag...

Abstract

The invention discloses a method and a device for managing an information array. The method comprises the following steps: step S102, setting one or a plurality of thresholds of information in the information array; step S104, receiving a priority level of an information receiving task in the information array according to adjustment of the thresholds. By adopting the invention, the success ratio of sending information can be improved so that the performance of the system cannot be reduced due to information resending; response timeover is reduced so as to improve the response speed of the system and the information processing ability of embedded system information.

Description

technical field [0001] The present invention relates to the field of embedded systems, and in particular, to a message queue management method and device. Background technique [0002] Because the message queue has the characteristics of transmitting messages of different lengths and the message boundary does not need to be managed by the user, many tasks of embedded devices use the message queue to communicate. [0003] However, in the case of using a message queue for communication, you must specify the maximum number of messages stored in the message queue when creating the message queue, and if the number of messages has reached the maximum value, sending a message to the message queue will return failure information. When the number of messages reaches the maximum value, the sending task will not be sent successfully until the task receiving the message takes away the message so that the number of messages in the message queue is less than the maximum value. [0004] ...
