Support the software architecture of high precision clock；Enter destination OS for high precision clock as the first event clock facility registration
Kernel, and when second clock event device bound in each processor being set as in first kind processor is updated to first
Clock event device, so that electronic equipment has the hardware architecture for supporting high precision clock.It is above-mentioned to be directed in first kind processor
The software architecture and hardware architecture that each processor is configured, so that each processing in electronic equipment in first kind processor
Device is able to achieve the control to the high-precision sleeping time of run program.
It should be noted that in the embodiment of the present invention, electronic equipment be based on SMP hardware framework, can in electronic equipment
With there are at least two processors.When the high precision clock configuration of the kernel of starting destination OS, it can corresponding target
Corresponding at least two processor of operating system calls high precision clock to configure corresponding kernel high-precision sleep function.In order to
Guarantee the reasonable control to the sleeping time of the business run in electronic equipment, and reduces starting high-precision to a certain extent
Clock is with postponing, and the operation of processor is born in electronic equipment.Need to configure the processor that can support the time precision of low precision
(the second class processor), and need to configure the processor (first kind processor) that can support high-precision time precision.
Specifically, can be by second of the corresponding kernel high-precision sleep function of each processor in the second class processor
Time precision is set as third time precision (third time precision is not higher than first time precision), every in the second class processor
One processor has bound the second clock event device for supporting the time precision of low precision, so that each in the second class processor
Processor can be realized and the sleeping time of the time precision of low precision is supported to control on above-mentioned software architecture and hardware architecture
System.
Furthermore it is possible to the mark according to the clock in destination OS, determines high precision clock, it further, will be high
Accuracy clock enters the kernel of destination OS as the first event clock facility registration, and is tied in first kind processor
Each processor.It is understood that each processor in first kind processor has defaulted binding second in some scenes
Event clock equipment in the embodiment of the present invention, needs each processor in first kind processor having defaulted the second of binding
Event clock equipment is updated to the first event clock equipment, so that each processor in first kind processor can be in hardware structure
The control for supporting the sleeping time of high-precision time precision is realized on frame.Also, start the height of the kernel of destination OS
For accuracy clock with postponing, each processor in first kind processor can call kernel high-precision sleep function, Ke Yi
The sleeping time control for supporting high-precision time precision is realized on software architecture.
Subsequent, based on the kernel of the destination OS after the completion of above-mentioned configuration, electronic equipment is obtaining target program
Afterwards, the object time precision and first time precision that can be carried according to target program, it is high-precision to determine whether target program needs
The control of the sleeping time of degree.When object time precision is higher than first time precision, i.e., determining target program needs high-precision
The control of sleeping time, at this point it is possible to by being run on any processor that target program is dispatched in first kind processor；Work as mesh
It marks time precision and is not higher than first time precision, that is, determine that target program does not need the control of high-precision sleeping time, at this point,
It is run on any processor that target program can be dispatched in the second class processor.
It is emphasized that in embodiments of the present invention, there must be at least one in above-mentioned electronic equipment and be arranged to
The processor of first kind processor, and, it is necessary to there are the processors that at least one is arranged to the second class processor.In a kind of reality
In existing mode, processor included in SMP hardware framework can be CPU, at this point, can generally be identified by " CPUn " different
CPU can set CPU0 to first kind CPU in a kind of plan of establishment, set second for other CPU in addition to CPU0
Class CPU.
In one implementation, there is likely to be not high to time required precision in the business run in electronic equipment
Business, that is, exist and do not need the program of high-precision sleeping time control (i.e. time precision entrained by program is not higher than the
One time precision).It is understood that realizing the control of the sleeping time of low precision compared to electronic equipment, electronic equipment is real
When the control of existing high-precision sleeping time, the operation burden of processor is larger.It handles at this time in order to reduce in electronic equipment
The operation of device is born, can by the above-mentioned program for not needing high-precision sleeping time control, be dispatched to support low precision when
