Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation description is it is clear that described embodiment is only a part of embodiment of the present invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of not making creative work
Embodiment, broadly falls into the scope of protection of the invention.
The embodiment of the invention discloses a kind of control circuit of job processor and electronic equipment, in the embodiment of the present invention
In, the signal depositing address interface output of deposit unit can reflect that deposit in address corresponding with depositing address interface is
No task load of having deposited instructs, and the input of multiple first order voltage output unit deposits ground from the different of deposit unit respectively
Location interface is connected, and can export first voltage, second level voltage output unit according to the signal depositing address interface output
Input be connected with the output end of multiple first order voltage output unit, can be defeated according to multiple first order voltage output unit
Exporting second voltage, therefore, second voltage is relative with the task load command quantity that deposit unit is deposited for the first voltage going out
Should, by second voltage driving frequency generating unit, can make needed for frequency and the task load of frequency generation unit output
Frequency corresponds to；In the present invention, because the job processor under in running order is the frequency being exported with frequency generation unit
Rate works, and therefore, the in running order operating frequency of job processor is corresponding with the frequency needed for task load, reduces electricity
The power consumption of sub- equipment, economizes on resources.
One embodiment of the invention discloses a kind of control circuit of job processor, this circuit can apply to mobile phone,
In the electronic equipments such as palm PC, panel computer.
As shown in figure 1, this circuit can include deposit unit 100, multiple first order voltage output unit 200, the second level
Voltage output unit 300, frequency generation unit 400；Wherein：
Deposit unit 100 is used for depositing the task load instruction of electronic equipment, and deposit unit has multiple addresses of depositing and connects
In the present invention it is possible to choose the deposit unit with different address interface according to the actual requirements, Fig. 1 is had mouth with deposit unit
Illustrate as a example having 8 to deposit address interface.
In FIG, deposit unit 100 include depositing address interface A0, deposit address interface A1, deposit address interface A2,
Deposit address interface A3, deposit address interface A4, deposit address interface A5, base address interface A6, deposit address interface A7 with
And deposit address interface A8.
It should be noted that each of deposit unit deposits address interface all address interface is corresponding to be posted according to depositing with this
Deposit whether deposited in address task load instruction come output signal；For example, when a certain of deposit unit deposits address interface pair
Depositing of answering has deposited task load instruction in address when, this is deposited address interface and can export high level, and works as this and deposit ground
Interface corresponding address of depositing in location is space-time, and this is deposited address interface and then exports low level.Certainly as another kind of way of realization,
Deposit address interface and can also deposit output low level when task load instructs in address in its corresponding depositing, in its correspondence
Deposit address be space-time, export high level.The mode specifically depositing address interface output signal can be according to actual conditions
Set, the present invention does not have restriction.
The input of multiple first order voltage output unit 200 deposits address interface from the different of deposit unit 100 respectively
It is connected；
First order voltage output unit is used for according to the signal output first voltage depositing address interface output.
It should be noted that in the present invention, the number of first order voltage output unit is not specifically limited, permissible
The situation of the task load according to electronic equipment is setting the first order voltage output unit of corresponding number.Fig. 1 is with first order electricity
As a example pressure output unit is 5；Certainly can also be other numbers, such as 3,8,10 etc., even more many.
It should be noted that multiple first order voltage output unit deposit address interface phase with which of deposit unit respectively
Even not concrete in the present invention limit, can according to deposit unit deposit task load instruction number determining.
It is assumed that during the task load order register deposit unit of electronic equipment taking Fig. 1 as a example, typically only take up and deposit ground
Deposit address corresponding to the interface A5 of location, then, multiple first order voltage output unit can respectively with deposit unit
The a certain address interface of depositing depositing below address interface A5 (address interface A5 is deposited in inclusion) is connected.
In FIG, first order voltage output unit 200 includes first order voltage output unit 201, first order voltage output
Unit 202, first order voltage output unit 203, first order voltage output unit 204, first order voltage output unit 205；Tool
Body, first order voltage output voltage 201 is connected with the address interface A0 that deposits of deposit unit 100, first order voltage output list
Unit 202 is connected with the address interface A2 that deposits of deposit unit 100, and first order voltage output unit 203 is posted with deposit unit 100
Deposit address interface A4 to be connected, first order voltage output unit 204 is connected with the address interface A6 that deposits of deposit unit 100, first
Step voltage output unit 205 is connected with the address interface A8 that deposits of deposit unit 100.
Wherein, first order voltage output unit is used for according to the signal output first voltage depositing address interface output.As,
The a certain of deposit unit is deposited when having deposited task load instruction in address, and depositing address with this, corresponding to deposit address interface defeated
Go out high level, and a certain address of depositing working as deposit unit is space-time, deposit the corresponding address interface of depositing in address with this and export
Low level.So, corresponding, when be connected with first order voltage output unit deposit address interface output high level when,
First order voltage output unit exports first voltage, when the deposit unit interface output being connected with first order voltage output unit is low
During level, first order voltage output unit does not export first voltage.
For another example, a certain of deposit unit is deposited when having deposited task load instruction in address, and to deposit address corresponding with this
Deposit address interface output low level, and a certain address of depositing working as deposit unit is space-time, deposits with this that address is corresponding to post
Deposit address interface output high level.So, corresponding, when depositing address interface with first order voltage output unit is connected
Output low level when, first order voltage output unit export first voltage, when with depositing that first order voltage output unit is connected
During unit interface output high level, first order voltage output unit does not export first voltage.
