Fig. 6 is the schematic diagram of resource regulating method based on polycaryon processor in third embodiment of the invention, should
For having the communication terminal of polycaryon processor, this communication terminal have TrustZone system, normal areas,
Safety zone and resource scheduling device 100, described TrustZone system connects normal areas, place of safety respectively
Territory and resource scheduling device 100.
Assume that APP (Application, application program) has the ordinary pages of non-verification, be then placed in general area
Territory；If the interface for password input that need to verify, then it is placed on safety zone to ensure cryptosecurity.When user is from general
When the logical page enters the Password Input page, system will switch to safety zone from normal areas.
1, user runs an APP, enters an ordinary pages, if it is notified that TrustZone, system adds
Carry this ordinary pages, need more processor cores.
2, TrustZone system calls resource scheduling device 100, initializes a parent process, and derives son
Process, each subprocess will call a processor cores, call an appropriate number of processor according to page need
Kernel.
3, the behaviour in service of the CPU of normal areas is monitored by resource scheduling device 100, along with user
The service condition of browsing pages, resource scheduling device 100 can adjust being increased or decreased of CPU automatically.
4, when APP ejects the dialog box of input password in some ordinary pages, ordinary pages is hidden in
Backstage, owing to relating to cryptosecurity, TrustZone system will switch to safety zone from normal areas automatically.
If 5, notice TrustZone system in safety zone loads this cryptographic check page, need more processor
Kernel.
6, TrustZone system will call resource scheduling device 100, derive from from the most initialized parent process
New subprocess calls new processor cores.If the subprocess of current CPU is the most occupied, need
The new subprocess of idle condition is recalled, if subprocess is not after first terminating at least one subprocess of conventional system
The most occupied, then can directly invoke the new subprocess of idle condition.
7, being hidden in backstage due to ordinary pages, reduce the demand of cpu resource, scheduling of resource fills
Put 100 by terminate at least one of which subprocess reduce the expense to cpu resource, reach freely to dispatch with
Save the purpose of resource.
If 8 are switched to normal areas by safety zone, resource scheduling device 100 automatically controls minimizing place of safety
The processor cores that territory uses, and increase the processor cores of normal areas.
In sum, the present invention provides scheduling of resource technology based on polycaryon processor, and proparea is worked as in detection in real time
The CPU in territory uses demand, and the process using demand to be current region scheduling number of matches according to described CPU
Device kernel.Whereby, the present invention can monitor the CPU behaviour in service of current region in real time, and according to working as proparea
The CPU behaviour in service free dispatch processor kernel in territory take quantity, thus to the CPU between zones of different
