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

Embodiment Construction

[0055] The present invention provides a multi-task scheduling system and method. The core of the present invention is: run one thread in the entire multi-task scheduling system, and at most one of multiple application programs that respectively implement different task functions can be in the running state .

[0056] The present invention will be described in detail below in conjunction with the accompanying drawings. The multi-task scheduling system described in this method is applicable to an RTOS-based user interaction system, such as a GUI system. Taking the GUI system as an example, the structure of the embodiment of the multi-task scheduling system of the present invention is as shown in Figure 1, including following modules: UI (User Interface, user interface) management module, application program module, input method driver and resource library . The functions of each module are as follows:

[0057] UI (User Interface, user interface) management module: the structur...

Abstract

The provided multitask scheduling system comprises: an UI management module, and an application program module. Wherein, the UI management module controls different programs in the application module, while at most one application program is running at any time. This invention is benefit to develop the interactive system that is simple and convenient.

Description

technical field [0001] The invention relates to the field of computer applications, in particular to a multi-task scheduling system and method. 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 credibility. 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 among them. [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 Interface) system realizes human-computer interaction in a graphical ...
