Specific embodiment
In order to meet the convenient and manual operability of carrying, in the portable electric of small
In the middle of sub-device, size is less and less generally to also imply that battery or the capacity of voltage source are got over
It is little.By taking an electronic equipment of Fig. 1 as an example, the power supply 110 of portable electron device 100 or
The electric supply installations such as person's battery are except for the main carrying electronic devices 140 as key electronic device
Outside power supply, the attached periphery electronic building brick 120 also to lay under tribute is powered.It is easy to
It is understood by, portable electron device 100 only shuts down, otherwise no matter portable electronic is filled
Put 100 be operated in any open state all must based on carrying electronic devices 140 power because
Main carrying electronic devices 140 are responsible for the normal operation of whole portable electron device 100, are in
Leading position, if its portable electron device 100 not as power supply supply cannot propagate into
Normal work.Different from main carrying electronic devices 140, periphery electronic building brick 120 is not running
When but can be need not power supply.In the industry cycle in particular for electronic equipment for, periphery electronics
The attribute kind of component 120 is substantially a lot, in the broadest sense for example common mouse, keyboard,
Display or audio frequency apparatus or interface circuit etc., and typical periphery in portable electronic equipment
Electronic equipment such as touch control screen etc..In FIG, two supply paths are specially designated,
Based on the path that main power source is powered, carrying electronic devices 140 are powered, and the path that sub- power supply is powered is
Periphery electronic building brick 120 is powered, and certainly, in actual system architecture, supply path may not
Only two, but for the ease of understanding and describing explanation, we are illustrated by taking two paths as an example
The spirit of the present invention.
Portable electron device 100 is except including power supply mentioned above 110, periphery electronics group
Outside part 120 and main carrying electronic devices 140, also including a control module 130, it is worth
It is noted that in the middle of the path that sub- power supply is powered, its control module 130 is connected to periphery electricity
Between sub-component 120 and power supply 110, in other words, judge whether need by control module 130
Power supply 110 is coupled to into periphery electronic building brick 120, and is thereby come for periphery electronic building brick 120
Power supply.In order to be unlikely to cause ambiguity or misunderstanding because of term different, periphery electronics here
Component 120 can be replaced by the first electronic installation, main carrying electricity in the context of this application
Sub-device 140 can be replaced by second electronic device in the context of this application, control mould
Block 130 can be replaced by periphery control chip.
Spirit of the present invention is that it is it that periphery electronic building brick 120 saves one of core of power consumption
In standy operation mode and switching between mode of operation can be waken up, as the term suggests, in the application
Here so-called standy operation mode be exactly force periphery electronic building brick 120 enter it is standby and need not
Operation, maximum power saving are not almost powered for it, and vice versa, so-called wake-up work
Pattern is just because that the holder or operator of electronic equipment has work to periphery electronic building brick 120
Make interaction demand, and force periphery electronic building brick 120 to depart from holding state and enter and wake up shape
State, at this moment needs to power for which.Equally, in order to be unlikely to cause discrimination because of term different
Justice is misread, and standy operation mode can be replaced by the first mode of operation here, and wake up work
Operation mode can then be replaced by the second mode of operation.
Referring to Fig. 2-3, first from an example being of universal significance illustrate the present invention than
The unique distinction of prior art.Control module 130 mainly includes a standby trigger element 131
With a wake-up trigger unit 132 and including a processing unit 134.Must highlight
Be, both standby trigger element 131 and wake-up trigger unit 132 than processing unit 134,
Their electric power system or powering mode is not quite similar.It is embodied in, as long as portable electronic dress
It is start to put 100, and standby trigger element 131 and wake-up trigger unit 132 are in normality meeting one
It is straight that uninterrupted power supply is come by the path that sub- power supply is powered, but processing unit 134 but may be used
It is not powered so that the path powered with sub- power supply is disconnected.Specifically, no matter periphery electronics
Component 120 is standy operation mode and wake-up mode of operation, standby trigger element 131 and wake-up
Trigger element 132 is all connected to the path that sub- power supply is powered, but processing unit 134 is only
The path that sub- power supply is powered is connected in the case where mode of operation is waken up, processing unit 134 is in standby work
It is but to disconnect that operation mode is the path powered with sub- power supply.The meaning adopted in this way exists
In processing unit 134 is used for driving periphery electronic building brick 120 and to periphery electricity in general
Sub-component 120 is powered, processing unit 134 in normal conditions have very strong operational capability and
The driving force of high intensity, the power consumption degree of processing unit 134 are also very high.If we will
134 power-off of processing unit, then the also just no longer power consumption of periphery electronic building brick 120, if conversely,
We power for processing unit 134, then periphery electronic building brick 120 can also be by processing unit
134 are powered.
In Fig. 2-3, the path that sub- power supply is powered is by a power supply for being connected to power supply 110
Line 135 is synchronous to standby trigger element 131, wake-up trigger unit 132 and processing unit 134
Power supply, because having informed that processing unit 134 is switched between power supply and power-off above, institute
An electronic switch 133 is provided between processing unit 134 and power line 135 with us
Perform the response action of the switching, but standby trigger element 131, wake-up trigger unit 132
Any electronic switch need not be then set and power line 135 between.Here the electronic switch for adopting
133 namely the power supply generally sayed of industry and frequency (clock) switch, it is with a control
End and first, second end, are controlled to make its by the low and high level of the signal for being applied to control end
Connect between first, second end or disconnect, the first end of electronic switch 133 may be coupled to
Power line 135 and the second end is then connected to processing unit 134；In addition, above-mentioned standby triggering
Unit 131 has two inputs, and one of input (i.e. first input end) is used for
Standby command INS1Input, and another input (i.e. the second input) then be used for receive
The wake-up signal S that 132 output end of wake-up trigger unit sendsW, and based on above-mentioned standby finger
Make INS1With wake-up signal SWStandby trigger element 131 exports triggering command to processing unit
134, the first mode of operation or the second mode of operation are operated in control periphery electronic building brick 120.
Under standy operation mode, patrol when wake-up trigger unit 132 does not receive effective first
Collect the wake-up instruction INS of state (such as high level)2When, wake-up trigger unit 132 can send
Wake-up signal S with the second logic state (such as low level)WTo standby trigger element 131.
Note, in order to avoid the deviation for understanding, slightly explaining here, in the industry cycle, wake up processing
The event stage, it is believed that wake-up trigger unit 132 does not receive calling out for effective first logic state
Wake up instruction INS2, refer to wake-up instruction INS2Needs reach expected in default time quantum T
Correct number of pulses is just characterized and refers to wake-up instruction INS2Effectively, this is in order to avoid pseudo- wake events
Generation.For concrete analysis, if first, waking up instruction INS2In default time quantum T
Always low level and without high level occur, then have no doubt wake up instruction INS2Certainly it is invalid
, that is to say, that wake up instruction INS2There is the secondary of high level pulse in default time quantum T
Number is zero.Even if second, waking up instruction INS2There are some high electricity in default time quantum T
Flat pulse, but these pulse numbers for occurring are inconsistent with expected correct number of pulses,
Also characterize wake-up instruction INS2It is invalid.
Continue from the preceding paragraph the standy operation mode of discussion, if wake-up trigger unit 132 is not received
The wake-up instruction INS of effective first logic state2, consequence is, wake-up trigger unit 132
Send the wake-up signal S with the second logic state (low level)WTo standby trigger element 131.
In wake-up signal SWUnder the premise of being low level, if standby trigger element 132 is received again
The first logic state (high level) standby command INS1, then 132 meeting of standby trigger element
Be triggered one critically important response action of generation, namely standby trigger element 132 sends one
Output result S of the second logic state (low level)OUT, because output result SOUTIt is coupled to
The control end of electronic switch 133, the low level that this stage control end receives can be by electronic switch
133 clamp down in off-state, so realize by control module 130 come cut off the electricity supply 110 pairs it is all
The power supply of side electronic building brick 120.
In the case where mode of operation is waken up, when wake-up trigger unit 132 receives effective first logic
The wake-up instruction INS of state (such as high level)2When, wake-up trigger unit 132 can send tool
There is the wake-up signal S of the first logic stateWTo standby trigger element 131.Here it is considered that wake-up is touched
Bill unit 132 receives the wake-up instruction INS of effective first logic state2, refer to that wake-up refers to
Make INS2Needs reach expected correct number of pulses in default time quantum T and just characterize and refer to and call out
Wake up instruction INS2Effectively.The mode of being implemented is various, at some as optional but nonessential
Embodiment in, if the arteries and veins of expected correct number can be detected within the specified time period
The edge of punching, rising edge or trailing edge, then pulse are identified2,
And the edge of pulse then characterizes the quantity of pulse.
Continue from the preceding paragraph under the wake-up mode of operation of discussion, if wake-up trigger unit 132 is received
The wake-up instruction INS of effective first logic state (such as high level)2When, consequence is to call out
Awake trigger element 132 sends the wake-up signal S with the first logic state (high level)WGive
Standby trigger element 131.In wake-up signal SWOn the premise of being high level, do not consider further that standby
The standby command INS that trigger element 132 is received1Logic state, directly so that standby triggering is single
Unit 132 is triggered one response action of generation, namely standby trigger element 132 sends one the
Output result S of one logic state (high level)OUT, because output result SOUTIt is coupled to electricity
The control end of son switch 133, the high level that this stage control end receives can be by electronic switch 133
Clamp down in on-state, and then realize by control module 130 power supply 110 being met to periphery electricity
The power supply of sub-component 120.
Fig. 2 is one and has the embodiment for extensively representing meaning, and Fig. 4 is then one and employs
Realizing the optional mode of the embodiment, we are discussed some electronic devices and components with Fig. 4 now
A kind of realization means of the present invention.
Referring to Fig. 4, standby trigger element 131 includes a phase inverter 131a and an OR gate
131b, and wake-up trigger unit 132 then includes a counter 132a and a comparator
132b.Specific connected mode is that the input of phase inverter 131a is used as to receive wake-up instruction
INS1And the output end of phase inverter 131a is connected to an input of OR gate 131b.With
And counter 132a is used as to receive wake-up instruction INS2, and counter 132a will wake up instruction
INS2Comparator 132b is arrived in high level pulse count results output in preset amount T, and
(threshold value is generally by a threshold register with a threshold value by count results for comparator 132b
Storage and can program) compare after, a wake-up signal is produced so as to by comparative result
SWAfterwards, by wake-up signal SWIt is transported to another input of OR gate 131b.If wake-up refers to
Make INS2High level pulse in the preset amount T actual count result cannot with it is default just
Really pulse number matching is equal, then the comparative result of digital comparator 132b causes what it exported
Wake-up signal SWFor logic low.Vice versa, if waking up instruction INS2High level
Pulse actual count result in the preset amount T is just matched with default correct pulse number
Equal, then the comparative result of digital comparator 132b causes the wake-up signal S that it exportsWTo patrol
Collect high level.In addition, in order to avoid the number system of counter 132a gets muddled, if
Count results of the counter 132a in a preset amount T and default correct pulse number
Be not inconsistent, then invalid wake-up instruction INS is received depending on wake-up trigger unit 1322, now count
Device 132a needs to reset and resets to reset, and starts to count again next Preset Time
Instruction INS is waken up in amount2Pulse number with high level pulse.
Under standy operation mode, when counter 132a does not receive expected numbers purpose high level
The wake-up instruction INS of step-by-step counting2When, namely wake-up trigger unit 132 do not receive effectively
Wake up instruction INS2When, the count results of counter 132a cause comparator 132b to export one
Low level wake-up signal SWOR gate 131b is given, so output result S of OR gate 131bOUT
Depending on the standby command INS of phase inverter 131a inputs1Logic state.If we lead
It is dynamic to specify or be applied to standby command INS1For logic high, then OR gate 131b another
The output end of input namely phase inverter 131a is low level so that the output knot of OR gate 131b
Fruit SOUTIt is low level, thereby disconnects switch 133, and then realize by control module 130 cutting
Power supply of the power-off source 110 to periphery electronic building brick 120.
In the case where mode of operation is waken up, when counter 132a receives expected numbers purpose high level arteries and veins
The wake-up instruction INS that punching is counted2When, namely wake-up trigger unit 132 receives effectively wake-up
Instruction INS2When, the count results of counter 132a cause comparator 132b to export a high electricity
Flat wake-up signal SWOR gate 131b is given, so output result S of OR gate 131bOUTDepend on
Directly just by the wake-up signal S of high levelWClamp down on high level state.Thereby ON switch 133,
And then realize by control module 130 recovering confession of the power supply 110 to periphery electronic building brick 120
Electricity.
By embodiments of the invention, super low-power consumption effect is realized, in periphery electronic building brick not
During use, cut off the electricity supply, thus whole system can be made to possess longer behaviour when standby
Make the time.
More than, by explanation and accompanying drawing, give the typical case of the ad hoc structure of specific embodiment
Embodiment, foregoing invention propose existing preferred embodiment, but these contents are not intended as office
