The S1 pattern: CPU quits work, and at this moment, except through the cpu clock controller CPU being closed, miscellaneous part still runs well;
The S2 pattern: CPU closes, and at this moment, CPU is in the state of quitting work, and the cpu clock controller also is closed, but miscellaneous part still runs well;
The S3 pattern: the miscellaneous part except internal memory all is in the state of quitting work, and is also referred to as STR (Suspend to RAM suspends to internal memory);
The S4 pattern: memory information writes hard disk, and all parts all are in the state of quitting work, and is also referred to as STD (Suspend to Disk suspends to hard disk), and at this moment, system's primary power cuts out, but hard disk is still charged and can be waken up;
The S5 pattern: computing machine is in closed condition, all the parts Close Alls in the computing machine.
Under the S0 pattern; Computing machine is in normal operating conditions, i.e. first state of indication in following examples is under S1, S2, S3, S4 or S5 pattern; Computing machine is in and is abnormal operating state; Be second state of indication in following examples, can find out, the power consumption of the power consumption when computing machine is in first state when being in second state from foregoing description.
Below in conjunction with accompanying drawing and embodiment, specific embodiments of the invention describes in further detail.
Be illustrated in figure 1 as a structural representation of the computing machine of the embodiment of the invention, said computing machine has first state and second state, the power consumption of the power consumption when computing machine is in said first state when being in said second state, and said computing machine comprises:
I/O functional unit 102, said I/O functional unit 102 can carry out data interaction with said storage unit 101, gives said storage unit 101 with data transmission, perhaps, receives the data that said storage unit 101 transmits.
Said I/O functional unit 102 can be polytype equipment:
For example, said I/O functional unit 102 can be a card reader, at this moment; Said computing machine also comprises the draw-in groove that is connected with said card reader; External memory card (like SD card, mmc card, SDxC card etc.) can insert in the said draw-in groove, and when externally storage card inserted in the said draw-in groove, said card reader can be discerned said storage card; And can be from said storage card reading of data, perhaps in said storage card, write data.
Said I/O functional unit 102 can also be the control chip group of a support USB function; At this moment, said computing machine also comprises the usb socket that is connected with said control chip group, and external USB equipment (for example USB flash disk etc.) can insert in the said usb socket; When externally USB device inserts in the said usb socket; Said control chip group can be discerned said USB device, and can be from said USB device reading of data, perhaps in said USB device, write data.
In addition, said I/O functional unit 102 can also be a network interface card, can connect with external network, from the external network data download, perhaps, uploads data to external network.
Certainly, said I/O functional unit 102 can also be given an example at this for the equipment of other types no longer one by one.
In order to realize the object of the invention, make said computing machine when being in abnormal operating state, also can carry out the data interaction between said storage unit 101 and the said I/O functional unit 102, as shown in Figure 1, said computing machine also comprises:
When said computing machine is in second state; If a certain parts in said second processing unit 104, said storage unit 101 and the said I/O functional unit 102 have been in power-up state; 106 of then said control modules do not need to control once more said power supply unit 105 to be repeated to power on for these parts, only needs control to state power supply unit 105 and gets final product for the current parts that are in off-position in the above-mentioned parts power on.
Said second processing unit 104 can also can be integrated in (like Fig. 2, shown in Figure 3) on the said I/O functional unit 102 for a module (as shown in Figure 1) independently.
Compare with respect to prior art; At the current off-mode that is in of said computing machine; And in the time of need carrying out data interaction between said storage unit and the said I/O functional unit; The user need carry out the start operation; Make said computing machine get into said first state (also be normal operating conditions, promptly all parts of computing machine all need carry out work), can obtain under the common cooperation of the miscellaneous part of said first processing unit in computing machine has data transmission in the corresponding I/O interface of I/O functional unit.Control said storage unit and said I/O functional unit carries out data interaction by said first processing unit, accomplish data interaction between the two.Carry out data interaction by the said storage unit 101 of said second processing unit, 104 controls with said I/O functional unit 102 in the foregoing description; At this moment; Need not to carry out the start operation, only need said second processing unit 104 is powered on, said second processing unit 104 just can operate as normal.When said second processing unit, 104 operate as normal, just can obtain has data transmission in the corresponding I/O interface of I/O functional unit, thereby controls said storage unit and said I/O functional unit carries out data interaction.
