Multi-task queue scheduling system with scalable thread number and its implementation method

Abstract

The invention discloses a multi-task queue scheduling system with a scalable number of threads and an implementation method thereof. The system mainly consists of a task dispatcher, a working thread pool and a task queue, wherein the task dispatcher is an independent progress or thread, more than one working thread is created in the working thread pool, and is not directly related to the task queue, the task queue is a task sequencing queue which is created according to the task type, and the task dispatcher determines if the new working thread is dispatched or not according to the conditions of the task queue. The system has the advantages that the structure composition and logic design are reasonable and feasible, and the implementation is easy; one independent working thread or progress does not need to be created for each task type, so the system resources are greatly and effectively saved.

Description

technical field [0001] The invention belongs to the technical field of computer engineering, and relates to a multi-task queue scheduling system designed based on a working thread pool and an implementation method thereof. Background technique [0002] RTOS (Realtime operation system, real-time operating system) is the foundation and development platform of embedded application software, and is a real-time kernel with high reliability and reliability. RTOS packs resources such as CPU time, interrupts, I / O, timers, etc., and leaves a standard API (Application Program Interface) for users. Allocate CPU time. [0003] RTOS is usually installed in embedded systems to complete various functions in real time. These embedded systems usually have the characteristics of good real-time performance, small system size, limited resources and no graphical interface. Typical RTOS are: Vxworks, pSOS, Nucleus, eCos, uC / OS-II, etc. [0004] The GUI (Graphic User Interface, Graphical User I...

Problems solved by technology

Once there are complex connections between these application function modules, the requirements of these application function modules for system resources and devices (such as Camera, memory) will inevitably conflict, and it is difficult to maintain when implemented;

[0017] 2. If multiple applications to be implemented are used as a single application function module, it will bring huge maintenance difficulties to the collaborative development of multiple programmers, and will cause multiple programmers to develop the same module or a program staff to complete a large-scale module
