Embodiment 2

[0041] The system level of each program module in embodiment 2 can be determined as: IIC, GPIO, bus driver and setting management module belong to hardware abstraction layer; Data access middleware, message middleware, object middleware and digital television protocol stack belong to middleware layer ; Tuner, external power amplifier equipment and mobile memory belong to the peripheral equipment management module.

[0042] Step S202: Determine the dependencies among program modules belonging to the same system level.

[0043] Determine the dependencies between program modules belonging to the same system level, that is, to determine whether program modules belonging to the same system level need to call methods provided by other program modules at this system level, or access certain data in other program modules at this system level member. After the above judgments, in this embodiment, there is no dependency relationship between program modules belonging to the same system ...

Abstract

The invention provides a method and apparatus for starting a terminal device system program. The method comprises the following steps: dividing a plurality of program modules into a plurality of task groups, wherein at least one program module in each task group has a dependency relationship with the program modules in other task groups, and the program modules in the each task group have no dependency relationship. By means of the grouping manner, the dependency relationship between the program modules in the system program becomes clearer, when the system programs are started according to actual needs, related task groups can be directly adjusted according to the dependency relationship between the program modules, thereby enhancing the configuration performance and the expandability of starting the system program. In the method, the task groups are sequentially started according to the dependency relationship between the corresponding program modules, therefore the normal start of the program modules in the task groups can be ensured; and the program modules in the task groups are started in a parallel mode, which is conducive to shortening the start time of the system program and improving the utilization rate of the system resources.

Description

technical field [0001] The present invention relates to the technical field of terminal equipment, in particular to a method and device for starting a system program of a terminal equipment. Background technique [0002] The system program of the operating system of the terminal device usually includes multiple system levels such as hardware abstraction layer, middleware layer and peripheral device management module, and each system level includes multiple program modules with specific functions. Usually, system startup requires the participation of program modules at various levels. Since different program modules are used to implement different functions, there may be dependencies among program modules. For example, during system startup, a certain program module needs to call methods provided by other program modules, or access certain data members in other program modules. Start, the sequence of starting after the dependent program modules starts in turn. Usually, the ...
