Embodiment
To make the purpose, technical scheme and advantage of the embodiment of the present invention clearer, below in conjunction with the embodiment of the present invention
In accompanying drawing, the technical scheme in the embodiment of the present invention is clearly and completely described, it is clear that described embodiment is only
Only it is part of the embodiment of the present invention, rather than whole embodiments.Based on the embodiment in the present invention, ordinary skill
The every other embodiment that personnel are obtained under the premise of creative work is not made, belongs to the scope of protection of the invention.
The relation between the concept of application program, process and thread and three is described below.
Application program is the ordered set of one group of instruction.Process is the application program with certain standalone feature on some
Once operation activity on data acquisition system, it is the individual that system carries out Resource Distribution and Schedule.Thread is process
One entity, it is CPU scheduling and the base unit assigned, it is the base unit of the energy independent operating smaller than process；Thread
Oneself do not possess system resource substantially, only possess a little essential resource in operation, as program counter, one group are posted
Storage and stack, but it can share whole resources for being possessed of process with belonging to other threads of a process together.
Generally speaking, application program at least one process, process at least one thread.It is same to apply journey
Sequence is run on several data acquisition systems simultaneously, and it will belong to several different processes, that is to say, that same application can
With corresponding multiple processes.In traditional operating system, application program can not independent operating, as resource allocation and independent transport
Capable elementary cell is all process.Generally, several threads can be included in a process, they can be gathered around using process
Some resources, generally all it is the base unit using process as distribution resource in the operating system of thread is introduced into, and thread
The base unit as independent operating and independently dispatched.
The present invention provides a kind of power consumption management method, and Fig. 1 is the flow chart of power consumption management method embodiment one of the present invention, such as
Shown in Fig. 1, the method for the present embodiment includes：
S11, the state for obtaining each thread in the process that current system is run.

Loading condition current GPU would also vary from, the state of each thread in the process run by obtaining current system, can
To judge the current loading conditions of CPU and GPU.Specifically, for some application program, the application is being run for the first time
When program, that is, when initialize, the electronic equipment where the application program monitors institute under the application program automatically
The state of each thread in the process of operation, and the stage according to residing for the state of each thread determines the application program, and obtain
The loading condition of GPU, CPU corresponding to the different phase residing for the application program are taken, and then establishes rank residing for each application program
Section and the mapping table of CPU and GPU loading condition；It is or right as the different phase institute residing for artificial statistics application program
GPU, CPU for answering loading condition, and the load feelings in stage residing for each application program and CPU and GPU are established on an electronic device
The mapping table of condition.In subsequent applications program operation process, pass through stage and CPU residing for each application program for pre-establishing
With the mapping table of GPU loading condition, it is current to search CPU and GPU corresponding with the stage that each application program is presently in
Loading condition.
If the application program currently run has multiple, with reference to the stage searched obtained each application program and be presently in
Corresponding CPU and GPU current loading condition, determine the current total load situations of CPU and GPU.Such as：To can each it apply
Loading condition current CPU corresponding to the stage that program is presently in is added, and obtains the current total load situations of CPU, will be each
Loading condition current GPU corresponding to the stage that application program is presently in is added, and obtains the current total load situations of GPU.
