Benefits of technology

The technical effect of this patented technology allows for efficient monitoring and control over computer systems by automatically reassigning tasks based on their priority level. This helps maintain reliable performance even when there are changes or delays affecting certain parts of the program being executed.

Problems solved by technology

This patented technical problem addressed in this patents relates to improving the efficiency at managing multithreaded applications without sacrificing their functionality. Specifically, current methods are limited because they either miss all possible loops waiting too much when trying to fix them, leading to reduced performance or even failure overtime.

Embodiment Construction

[0022] The present invention will be further described in detail below in conjunction with the specific embodiments and the drawings.

[0023] The main idea of ​​the task adjustment method and device of the embedded software of the present invention is: first start a high-priority adjustment task, which is a timed task, and accepts the registration information of the adjusted task at any time, including at least the CPU occupancy rate Threshold; each adjusted task sends registration information to the adjustment task at the entrance of the task, and periodically sends the running status to the adjustment task; the adjustment task is based on the high and low thresholds of the CPU occupancy rate of each adjusted task application The actual CPU occupancy rate of the task is judged and adjusted for the running state of the adjusted task, so as to realize the dynamic adjustment of the resources occupied by the task.

[0024] The following is a further description of the present invention

Abstract

The invention discloses a task adjusting method for embedded type software and a device thereof. The method comprises steps as followed: S1, a high priority adjusting task is created, S2, the adjusting task receives registration information of an adjusted task, wherein the registration information at least comprises detecting cycle and high threshold value of CPU occupancy, S3, the adjusting task obtains the running status of the adjusted task according to the detecting cycle, and if the CPU occupancy of the adjusted task is higher than the high threshold value of CPU occupancy, then the adjusted task is released for a certain time. The invention utilizes a high priority adjusting task to count the running states of each task at real time, when the CPU occupancy of the adjusted task is higher than the set high threshold value of CPU occupancy, the adjusted task can be released for a while by the adjusting task, thereby guaranteeing system normal operation, and increasing system reliability.
