If in the array be not present the time term, it is also necessary to added in the array the current ID it is corresponding when
Between item, and set preset numerical value for the gsec in the time term of addition；In general preset numerical value is 0.
S103, when using preset the second gsec that need to be slept when the previous current thread and first microsecond
Between determine total gsec that the current thread need to sleep；
In this step, after getting the first gsec of the ID corresponding historical sleep duration, utilization is preset
The second gsec and first gsec that need to be slept when the previous current thread determine that the current thread need to be slept
The total gsec slept；It is described it is preset when previous current thread need to sleep duration the second gsec be hypothesis this work as
The gsec that preceding thread need to sleep.
Specifically, total gsec T1 that the current thread need to sleep is determined using formula (1)；
T1=(timeArray [id]+T) * delta (1)
Wherein, in formula (1), the timeArray [id] is first gsec, first gsec
Substantially refer to current thread before executing this sleep function, when the microsecond less than one millisecond stored in the array
Between；The T is the second gsec；The delta is thread response error.The thread response error is for measuring system

The time point for beginning to execute sleep function is denoted as Tstart, and the time point that the sleep function executes end is denoted as Tend.
So, the determination unit 23 can also calculate the thread response error delta using formula (2):
Delta=T2/ (Tend-Tstart) (2)
It should be noted that when the delta is equal to 1, illustrate preset to work as previous current thread and need to sleep duration
Second gsec T is just equal to the practical third gsec T2 to sleep of current thread；So the second gsec T is very
Accurately.
When the delta is greater than 1, illustrate preset to work as previous current thread and need to sleep the second gsec T of duration
The third gsec T2 that sleeps practical greater than current thread；So the determination unit 23 will be calculated at this time using formula (3)
Total gsec T3 that actual current thread need to sleep:
T3=timeArray [id]+T+ (timeArray [id]+T) * (delta -1) (3)
Wherein, described (timeArray [id]+T) * (delta -1) is time difference offset.
When the delta is less than 1, illustrate preset when previous current thread need to sleep the second gsec T of duration
The third gsec T2 that sleeps practical less than current thread；So the determination unit 23 will be calculated at this time using formula (4)
Total gsec T4 that actual current thread need to sleep:
T4=timeArray [id]+T- (timeArray [id]+T) * (delta -1) (4)
Wherein, described (timeArray [id]+T) * (delta -1) is time difference offset.
And when the error between delta and 1 is smaller, illustrate that the precision of sleep function USleep is bigger, CPU is consumed at this time
It is smaller, when the error between delta and 1 is bigger, illustrate that the precision of sleep function USleep is smaller, CPU consumption at this time is bigger.
After determining total gsec T1, when the call unit 24 is used to determine total microsecond using formula (5)
Between millisecond time M of the T1 relative to unit millisecond, sleep function precision has thus been navigated to Microsecond grade, has improved sleep letter
Several precision:
M=floor (T1,1000) (5)
Wherein, floor is bracket function
Then the call unit 24 determines the remaining gsec U of total gsec using formula (6), and utilizes formula
(7) the residue gsec U was saved into the historical sleep time corresponding with the ID.
U=T1-M*1000 (6)
TimeArray [id]=U (7)
After getting millisecond time M, call unit 24 judges that the millisecond time M is no for positive number, i.e., whether is greater than 0；If
Millisecond time M is positive number, then calls sleep function that current thread is slept M milliseconds.If millisecond time M is 0,
