Fig. 1 shows first embodiment of a kind of computer system at non-started state access voice data provided by the present invention, and this routine computer system 10 is by a power-supply unit 100 supply electric power.Computer system 10 is to be example with the portable computer, as less mini notebook computer (Netbook) of notebook computer (Notebook), volume or similar portable electric device etc.Power-supply unit 100 can be the battery or the AC power supplies of portable computer, is used to supply whole computer system 10 needed electric power under various operating states.The operating state of computer system 10 comprises a starting state (operation mode) and a non-started state (non-operation mode).The non-started state of present embodiment indication comprises according to the standard of advancing rank configurations and power interface (ACPI), to the defined dormant state of system power supply state (system power state) (Hibernation, S4) and off-mode (Soft off, S5); Starting state then refers in the system power supply state, the state except dormancy and off-mode.
The power-supply unit 100 of computer system 10 is not only to provide electric power during for starting state in computer system 10; Unless power-supply unit 100 separated fully with computer system 10 or remove, otherwise, still have the sustainable part running of some system element when computer system 10 during at non-started state.For example in general computer system, embedded controller (Embedded Controller, EC) can continue to obtain the stand-by electric (standby power) of power-supply unit 100 and detect the power supply supply status of computer system, first embodiment of the invention is then done explanation with embedded controller as the condition monitoring unit of required computer system 10.It should be noted, condition monitoring unit among first embodiment also can be any device that detects the power supply supply status of computer system 10 in the computer system 10, and those skilled in the art can replace embedded controller with other device according to actual demand.
As mentioned before, because condition monitoring unit 102 continues to receive the power supply that power-supply unit 100 is provided, so condition monitoring unit 102 can continue the situation that computer system 10 is given in 100 power supplies of monitoring power supply feeding unit, for example the size of current exported of monitoring power supply feeding unit 100 determines whether being provided with (assert) state switching signal 102_S.
Be with, when condition monitoring unit 102 judges that computer system 10 is in non-started state, for example current value ratio one predetermined critical exported of power-supply unit 100 is when low, condition monitoring unit 102 will be provided with state switching signal 102_S, so power supply switch unit 124 will be closed (close) according to the indication of state switching signal 102_S, and power supply switch unit 122 is opened (open) according to the indication of state switching signal 102_S, so that power-supply unit 100 stops transmission voltage to logical operation module 120, and audio frequency control module 104 required running voltages can be imported audio frequency control module 104.
In addition, the state switching signal 102_S that is set up also control data switch unit 106 exports voice data via the output terminal (becoming the output data 110_SO of data access unit 110) of data access unit 110, by the binding transmission of data switch unit 106, be regarded as the input data 104_SI of audio frequency control module 104 at last and feed-in audio frequency control module 104 is done further processing.On the other hand, the voice data that the state switching signal 102_S that is set up also makes audio frequency control module 104 handle is sent to data switch unit 106 as output data 104_SO, be sent to audio output unit 108 subsequently again, input data 108_SI as audio output unit 108 plays for audio output unit 108.With regard to the enforcement of reality, the audio output unit 108 of present embodiment can further couple with earphone output terminal (earphone output), loudspeaker horn devices such as (speaker) mutually.In addition, the also exportable audio frequency of audio output unit 108 is to the Bluetooth transmission module or the frequency modulation transmitter module (FM) of bluetooth earphone.
The audio frequency control module 104 of present embodiment can be a codec, MP3 decoding module for example is built in the storage element (for example hard disk) or the stored voice data of external storage element (for example USB external hard drive) of computer system 10 in it can read by data bus.Afterwards, again via interior processor (as digital signal processor (DSP) or microprocessor (microprocessor)) and the converter devices (not being shown among the figure) such as (as DAC) that is built among the audio frequency control module 104, compile, handling procedure such as decipher or format conversion.Above-mentioned voice data can comprise that MP3, WAV or WMA etc. are compatible with the data layout of MP3 decoding module.
For example, audio frequency control module 104 necessary built-in IDE/PATA/SATA driver or software modules just can become aggressive device to read the data in the hard disk; Similarly, audio frequency control module 104 essential built-in USB driver or software modules just can become aggressive device to read the voice data in the USB external hard drive.Those skilled in the art can increase the driver of audio frequency control module 104 inside according to actual demand, to read required voice data.Moreover, computer system 10 also can comprise the control panel (figure does not show) with several operating units (as play button, sound volume button), the user can produce control command by controlling these operating units, carries out corresponding Audio Processing operation in order to control audio control module 104.
Otherwise when computer system 10 is starting state, when condition monitoring unit 102 predicts the current value that offers computer system 10 at present and is higher than predetermined critical, setting (de-assert) state switching signal 102_S will be cancelled in condition monitoring unit 102.Power supply switch unit 122 is promptly closed according to the indication of cancelling the state switching signal 102_S that is provided with, then unlatching of power supply switch unit 124, make power-supply unit 100 stop running voltage is inputed to audio frequency control module 104, change running voltage input arithmetic logic module 120, for the instructions of logical operation module 120 computer system 10 under starting state.
When state switching signal 102_S cancellation is provided with, also control data access unit 110 transmits the data (being output data 110_SO) that read via data switch unit 106, become the input data 116_SI of logic controller 116, handle by other element of logic controller 116 collaborative logical operation module 120.In addition, data switch unit 106 also transmits logical operation module 120 voice data that finishes of handling according to the state switching signal 102_S that cancellation is provided with: send output data 116_SO by logic controller 116, by data switch unit 106 its input data 108_SI as audio output unit 108 is sent to audio output unit 108 again, makes audio output unit 108 outputting audio datas.
Fig. 2 describes the inner structure of data switch unit 106, wherein comprises audio frequency input switch unit 1060 and audio frequency output switch unit 1062.Audio frequency input switch unit 1060 comprises one and switches switch 10602, and it is that the indication of the state switching signal 102_S that exported according to condition monitoring unit 102 is switched.Because state switching signal 102_S can be set up when computer system 10 is in non-started state, it switches to control its switch 10602 input end of audio frequency control module 104, so the output data 110_SO that is taken out by data access unit 110 will become the input data 104_SI of audio frequency control module 104.
In addition, audio frequency output switch unit 1062 comprises one and switches switch 10622, it also is controlled by state switching signal 102_S, and switch to the output terminal of audio frequency control module 104 during in non-started state in computer system 10, to receive the audio frequency output data 104_SO that is transmitted by audio frequency control module 104, again this output data 104_SO is play as the input data 108_SI that is sent to audio output unit 108 subsequently.It should be noted, in practical application, on-off circuit (switch circuit) can be set at the motherboard of computer system, construct above-mentioned change-over switch 10602 and 10622, therefore the manufacturing cost for computer system integral body can not increase too much, and whole system complexity can be too not high yet.
When state switching signal 102_S cancellation is provided with, audio frequency input switch unit 1060 is according to the control of state switching signal 102_S, change-over switch 10602 is switched to the input end of logic controller 116, the output data 110_SO that data access unit 110 is taken out becomes the input data 116_SI of logic controller 116, handles the data that receive in order to logic controller 116 collaborative other elements.Similarly, audio frequency output switch unit 1062 is also according to the control of state switching signal 102_S, change-over switch 10622 is switched to the output terminal of logic controller 116, so that with logical operation module 120 voice data that finishes of handling, via logic controller 116 (as the output data 116_SO of logic controller 116), audio frequency output switch unit 1062, after becoming the input data 108_SI input of audio output unit 108 at last, play.
What deserves to be mentioned is, audio frequency control module 104 among first embodiment system's 10 original data access unit 110 and the audio output units 108 that can use a computer, switching by data switch unit 106, make audio frequency control module 104 when computer system 10 is in non-started state, can receive voice data and outputting audio data.Computer system 10 has not been required to be under non-started state and has inputed or outputed voice data, and extra system element is set, and when increasing computer system 10 use value, can't make the manufacturing cost of computer system 10 increase too many.
Embodiment as for state switching signal 102_S reality, the general output that embedded controller had can be gone into (GPIO) one of them pin position and be connected to audio frequency control module 104, and go into the pin position by this general output and send a high potential signal to audio frequency control module 104, with notification audio control module 104 and begin follow-up Audio Processing operation.So switching mode of state switching signal 102_S, in the time of can detecting computer system 10 in condition monitoring unit 102 and be in starting state (for example previously described when current value is higher than predetermined critical), cancellation immediately being provided with state switching signal 102_S (for example drawing high its current potential to noble potential); Same, when detecting computer system 10 in condition monitoring unit 102 and being in non-started state (when for example previously described current value is lower than a predetermined critical), the potential value of state switching signal 102_S can be switched to electronegative potential.
Fig. 3 describes the power supply switching state figure of first embodiment of the invention.When the state switching signal 102_S powered-down switch unit 124 that is set up, make when audio frequency control module 104 begins to obtain required running voltage, power supply switch unit 122 can be opened simultaneously, so cut off the power supply that offers logical operation module 120.In addition, because unit such as data switch unit 106, audio output unit 108 and data access unit 110 in the present invention, be in computer system 10 all to need work under starting state or the non-started state no matter be, so power-supply unit 100 will continue to provide their required running voltage, and not influenced by the state (that is whether being set up) of state switching signal 102_S.
It should be noted, the running voltage of computer system 10 each unit is not necessarily identical, the power supply status figure that is depicted in Fig. 3 simplifies for convenience of description and in addition, those skilled in the art should know when the enforcement of reality, should carry out circuit layout (layout) with the required running voltage in each unit.
It should be noted, after computer system 10 enters starting state, will receive the electric power of power-supply unit 100 by other system element outside the computer system 10 sound intermediate frequency control modules 104 (for example network control unit, logical operation module 120 etc.).If the user is when desiring under starting state playing audio-fequency data, computer system 10 will be utilized the control of CPU (central processing unit) 114 by logic controller 116 (as south, north bridge chips), read audio file stored in the hard disk or the audio file by the network control unit access the Internet, will these file conversions or encoding and decoding output to audio output unit 108 again after handling.
With general notebook computer, but power-supply unit 100 only has six to eight hours in that the continuous power-on time of starting state is on average about.Yet, according to many users' custom, many times computer system 10 is started, expends a large amount of power supplys fully, but not to carry out the complex calculations operation, and only want simple operation such as listoning music or song (in other words, only as the usefulness of music player); At this moment, adopt the means that present embodiment proposed, can be under the state of computer system 10 shutdown or standby, but start the audio frequency control module 104 of independent processing data, and playing audio-fequency data indispensable unit come displaying audio file, and during with playing audio-fequency data will with less than element closed (for example not providing power supply) to them, so not only can exempt the program that the user makes or have much ado and starts shooting, and do not need power supply to other system element to be processed of not working (network control unit for example, logical operation module 120 etc.), so just can reach the demand of power saving.By the means that present embodiment proposed, identical power-supply unit 100 can allow the audio frequency control module longer time of 104 runnings.
Audio frequency control module 104 in the present embodiment receives the mode of electric power, be directly audio frequency control module 104 to be connected with power-supply unit 100 circuit, but voltage voltage regulation unit 112 can be set between the two, use after the voltage drop of power-supply unit 100 output is low to moderate the running voltage that is suitable for audio frequency control module 104; Also or directly utilize standby power (Standby power) as power source, also be enough to support the required voltage of audio frequency control module 104 runnings.
