Fig. 1 is the embodiment flow chart of the determination method of a CPU usage provided by the invention, the CPU usage
The method of determination can be applied in CPU, as shown in figure 1, the determination method of the CPU usage comprises the following steps：
Step 101：Determine whether regulation goal process, if regulation goal process, perform step 102- steps 105, if
Target process is not dispatched, then performs step 106.
Step 102：Mark based on target process obtains structure corresponding to target process.
Step 103：Based on structure, the very first time piece that target process takes when last target process is called is obtained
CPU occupied second timeslices when being called with last target process.
Step 104：Obtain the 3rd timeslice of current goal process occupancy and current CPU total time piece.
Step 105：Based on very first time piece, the second timeslice, the 3rd timeslice and total time piece, target process is determined
CPU usage.
Step 106：The occupancy for determining target process is zero.
In a step 101, in one embodiment, CPU determines whether regulation goal process, if regulation goal process, holds
Row step 102- steps 105, if not dispatching target process, perform step 106.
In a step 102, in one embodiment, the corresponding structure of each process, different structures are corresponding not
With mark, mark can be that process name claim, sequence number etc. can distinguish the mark of different structure body.If CPU regulation goal processes,
CPU obtains the mark of target process, and marks of the CPU based on target process obtains structure corresponding to target process, the structure
Corresponding mark is consistent with the mark of target process.
In step 103, in one embodiment, CPU obtains target when last target process is called from structure
CPU occupied second timeslices when the very first time piece and last target process that process takes are called.Art technology
Personnel are it is understood that include at least one data in structure.It is as follows, it is a structure example：
Wherein, " process_usage " is structure name；" long " is the specifier of data type；“last_process_
Time " is the very first time piece that target process takes when last target process is called；" last_cpu_time " is the last time
CPU occupied second timeslices when target process is called.
At step 104, in one embodiment, CPU can obtain that current goal process takes by statistical module the
The total time piece of three timeslices and current CPU.It will be appreciated by persons skilled in the art that the 3rd of current goal process occupancy the
Timeslice and current CPU total time piece can be counted by statistical module, specifically, when how statistical module counts the 3rd
Between piece and current CPU total time piece process refer to the associated description of prior art.

Step 202：Determine the second time difference between the second timeslice and total time piece.
Step 203：Proportionate relationship based on very first time difference with the second time difference, determine the CPU usage of target process.
Step 204：Very first time piece is updated to the 3rd timeslice, the second timeslice is updated to total time piece.
In step 201- steps 203, with reference to the associated description in Fig. 1 steps 105, with CPU by formula y=(a-b)/
(c-d) exemplified by the CPU usage for determining target process, wherein a is the 3rd timeslice, and b is very first time piece, and c is current CPU's
Total time piece, d is the second timeslice.CPU determines that the very first time between very first time piece b and the 3rd timeslice a is poor；CPU is true
Fixed the second time difference between second timeslice d and total time piece c；Ratios of the CPU based on very first time difference with the second time difference
Relation, determine the CPU usage y of target process.
In step 204, very first time piece is updated to the 3rd timeslice by CPU, and the second timeslice is updated into total time
Piece, when being called in order to which target process is next, after the very first time piece after renewal can be obtained by structure and is updated
Second timeslice.It should be noted that the numerical value of very first time piece and second timeslice of the structure in original state is zero.
It will be appreciated by persons skilled in the art that step 204 can be after step 104 either step front/rear execution, walk herein
Rapid 204 execution sequence is merely illustrative.
