Embodiment
Consult Fig. 1, be the method flow diagram of automatic adjustment CPU frequency of operation of the present invention, at first the trigger condition (step 102) of start sensor (step 101) setpoint frequency adjustment; Monitor this sensor in real time and detect its state value (step 103); Relatively this trigger condition and sensor states value (step 104) in real time; Adjust the frequency of operation (step 105) of CPU in real time according to comparative result.
Wherein, this sensor can be voltage, electric current, temperature or load cell, or their combination, and this sensor all has its monitoring module separately, in order to real-time monitoring host computer system, and its detected value of output.
Trigger condition can be set according to the single condition of single-sensor, also can set according to the combination condition of a plurality of sensors.
Can be to preestablish before computing machine dispatches from the factory and be stored in this computer system the opportunity of setting trigger condition, also can be when the user starts shooting, and according to circumstances set and be stored in this computer system at any time by the user.
Whether the condition that system sets according to the user is differentiated should adjust the frequency of CPU this moment, the frequency of its CPU can be carried out two-way adjustment, i.e. raising frequency or frequency reducing, certainly, when if working environment changes the trigger condition of no show sensor, then keep the frequency of operation of former CPU.
Consult Fig. 2, be the device architecture figure of automatic adjustment CPU frequency of operation of the present invention, comprise at least one group sensor 201, one setup units 202, one storage elements 203, one comparing units 204, one frequency adjustment units 205.
Wherein, sensor 201 is in order to detection host work state, and its detected value of output; The trigger condition that setup unit 202 is adjusted in order to setpoint frequency; Storage element 203 is in order to store the trigger condition of setting by this setup unit; Comparing unit 204 in order to will by this sensor to the host work state compare with the trigger condition that is stored in storage element; Frequency adjustment unit 205 is in order to adjust the frequency of operation of main frame according to the comparative result of comparing unit.
Be provided with at least one group sensor 201 in the main frame, wherein this sensor can be a voltage sensor, or current sensor, or temperature sensor, or load cell, also can be the combination of these different sensors.Above-mentioned sensor 201 is the key points that are arranged at host computer system, also can multiple sensor be set in the many places key point, so that the variation of Ling Min detection main frame running environment more.These sensors all cooperate monitoring module separately, carry with the weight of the voltage on the real-time monitoring host computer, electric current, temperature or program, and the real-time then reacting condition with these states is given system.
The user can when start by the sensor in setup unit 202 initialization systems, and can be, and the trigger condition of setting is stored in the storage element 203 according to the combination of the multiple trigger condition of different requirements set.In use subsequently, system can pass through comparing unit 204, and according to the system status information that condition makes up and sensor 201 is collected that the user sets, the frequency of differentiating CPU this moment should be promoted or descend.
Under any operating system, when main frame need be handled a heavily loaded program, or main frame need handle the time marquis of a program for a long time, and system can be automatically according to demand, adjust the frequency of CPU, reply just often when system, when perhaps routine processes finished, the frequency of CPU just can be aligned by system, with normal frequency of operation work, whole handoff procedure needn't rely on software processes fully, the main frame of also need not resetting, and handoff procedure can not influence the program of handling.
The present invention also can be used alone as temperature monitor and use, and when the main frame temperature was too high, system can adjust frequency automatically, and the main frame temperature is descended, and when the main frame temperature is lower than when setting temperature, system can be with higher frequency work.Reaction time of the present invention is fast, and does not have compatibility issue, and under any operating system, when modification or setting sensor, the main frame of must not resetting just can be finished and set action, therefore can reach usefulness the most stable and maximum.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Be that all equalizations of doing according to content of the present invention change and modification, all contained by scope of the present invention.
