Figure 1A is the calcspar of the computer system that illustrates according to one embodiment of the invention.See also Figure 1A, computer system 100 comprises internal memory 110, chipset 120, embedded controller 130, and Basic Input or Output System (BIOS) (Basic Input/Output System, BIOS) 140.Wherein, carry out in working order the time when computer system 100 operating system is arranged.
In the present embodiment, chipset 120 comprises central processing unit 121, north bridge chips (north bridge) 123 and South Bridge chip (south bridge) 125, and internal memory 110 is the north bridge chips 123 that are coupled in the chipset 120, and embedded controller 130 is the South Bridge chips 125 that are coupled in the chipset 120 with Basic Input or Output System (BIOS) 140.Both see through north bridge chips 123 and South Bridge chip 125 periphery component interconnection and link up.Wherein, north bridge chips 123 is responsible for the signal transmission between central processing unit 121, internal memory 110 and the peripheral component interconnect bus, and South Bridge chip 125 then is in order to control other peripherals.
Embedded controller 130 is in order to the keyboard input medias such as (not illustrating) of control computer system 100, and can manage power supply.
Basic Input or Output System (BIOS) 140 for example is the program code in the last ROM (read-only memory) (Read Only Memory, ROM does not illustrate) of motherboard (not illustrating) that is stored in computer system 100.In the present embodiment, Basic Input or Output System (BIOS) 140 is also especially in order to carrying out a special mechanism when computer system 100 shutdown, and then computer system 100 is imported standby (ACPI S3) states.And when started computer system 100 next time, (Power On Self Test POST), and reached the purpose of quick startup computer system 100 to omit complete start selftest.
Figure 1B is the calcspar of the computer system that illustrates according to another embodiment of the present invention.The computer system 100 ' of present embodiment is similar to the computer system 100 shown in Figure 1A, thus below only describe at the difference place.Shown in Figure 1B, in the chipset 120 ' of computer system 100 ', comprise the integral chip 122 of having integrated central processing unit and north bridge chips, and South Bridge chip 125.And internal memory 110 is the integral chips 122 that are coupled in the chipset 120 ', and embedded controller 130 is the South Bridge chips 125 that are coupled in the chipset 120 with Basic Input or Output System (BIOS) 140.Because except the difference of above-mentioned coupling mode, the function of each member of computer system 100 ' is all identical with counterpart member in the computer system 100, so do not giving unnecessary details at this.
What must specify is, in other embodiments of the invention, Basic Input or Output System (BIOS) 140 also can be coupled to embedded controller 130 (as the computer system 100 of Fig. 1 C " shown in).
In order to further specify the detailed operation mode of Basic Input or Output System (BIOS) 140 when computer system 100 is shut down, below come especially exemplified by another embodiment that the present invention will be described.Fig. 2 is the process flow diagram of the closedown method of the computer system that illustrates according to one embodiment of the invention.Please consult Figure 1A and Fig. 2 simultaneously.
For the computer system 100 that belongs to duty, press START button or " Ctrl+Alt+Del " Macintosh of desktop the user, when then selecting " shutdown " option, shown in step S210, Basic Input or Output System (BIOS) 140 can be intercepted the shutdown command that operating system is sent.
Then in step S220, Basic Input or Output System (BIOS) 140 notice embedded controllers 130 prepare to enter holding state.Particularly, Basic Input or Output System (BIOS) 140 can see through the flag value of setting embedded controller 130, and then the indicator (indicator) of notice embedded controller 130 turning off standby states, thereby what make that embedded controller 130 learns that next computer system 100 will enter is holding state.
Then shown in step S230, Basic Input or Output System (BIOS) 140 is according to the content of one or more correlation buffer in the holding state setting chip group 120.In the present embodiment, Basic Input or Output System (BIOS) 140 will setting chip group 120 in the content of correlation buffer of South Bridge chip 125.This measure is that then chipset 120 carries out Status Change because operating system can write relevant setting value the buffer in the chipset 120 when preparing to enter off-mode (S5 state).Therefore, really enter off-mode for fear of chipset 120, Basic Input or Output System (BIOS) 140 can change the content of buffer into the setting value relevant with holding state.
Shown in step S240, keep the present operating state data (this operating state data is to be retained in internal memory 110) of computer system 100.At last shown in step S250, embedded controller 130 control power circuits are kept power supply to internal memory 110 and are preserved wherein operating state data, and then make computer system 100 enter holding state.
What deserves to be mentioned is, because present embodiment is to see through Basic Input or Output System (BIOS) 140 notice chipsets 120 to enter holding state with embedded controller 130 but not enter off-mode, but the behavior of operating system itself does not change, so operating system assert still that computer system 100 prepares to enter is off-mode.In other words, from the angle of operating system, the data of its state and storage all with generally enter off-mode and be as good as.
Below will the detailed operation mode of each member in the computer system 100 be described when under the user during less important unlatching computer system 100 with Fig. 3.
At first shown in step S310, the user presses the power key of computer system 100 to start the power supply of computer system 100.In one embodiment, Basic Input or Output System (BIOS) 140 can be by the flag value that reads embedded controller 130 or other non-voltile memory to judge whether computer system 100 experienced each step shown in Figure 2 when shutting down last time.If flag value shows that computer system 100 before had been to close according to traditional process, 140 of Basic Input or Output System (BIOS)s can be carried out complete start selftest, and (Power On Self Test POST) starts computer system 100.That is in the case, must carry out initialization action to all nextport hardware component NextPorts.
If but flag value shows computer system 100 was to replace and enter off-mode to enter holding state when shutting down last time, then shown in step S320, Basic Input or Output System (BIOS) 140 judge computer system 100 be in holding state during whether any hardware change of generation is arranged.For instance, hardware change comprises internal memory change (for example changing or Extended RAM), central processing unit change (for example changing central processing unit), peripherals change (for example hard disk change, various expansion board (Extended card) change, WLAN (wireless local area network, WLAN) and the change between 3G network or the like), and real-time frequency (Real Time Clock, RTC) one of them or its combination person of power supply change (for example changing the battery of real-time frequency chip).
In detail,, represent that present related hardware model can be different with the hardware configuration that internal memory 110 is write down if internal memory change or the change of real-time frequency power supply take place, and if internal memory takes place changes, then may lose the operating state data of original reservation.The base this, if Basic Input or Output System (BIOS) 140 judges that computer system 100 has the generation hardware change, then shown in step S330, Basic Input or Output System (BIOS) 140 will be carried out complete start selftest (all nextport hardware component NextPorts are carried out initialization action) and be started computer system 100.
Yet if hardware change does not take place computer system 100, in step S340, Basic Input or Output System (BIOS) 140 can utilize the operating state data that is kept in the internal memory 110 to reply the setting of the correlation buffer of chipset 120 so.
In addition, Basic Input or Output System (BIOS) 140 also can be carried out initialized action to the hardware unit of minority.Specifically, shown in step S350, because visual graphic array (the Video Graphics Array of computer system 100, VGA) related data of display (not illustrating) can't be stored in internal memory 110, but can be stored in the chip and internal memory of VGA display itself, therefore, Basic Input or Output System (BIOS) 140 can start the visual graphic array through the initialization action of the VGA BIOS (VBIOS/DXE Driver) that carries out the VGA display.
Then shown in step S360, in order to want to read the hard disk (not illustrating) of computer system 100, Basic Input or Output System (BIOS) 140 will be carried out several the affirmation programs about hard disk.For instance, whether Basic Input or Output System (BIOS) 140 can be checked interruptable controller, normal as the function of INT 13 breaks in service to judge.In addition, support rank host controller interface (Advanced Host Controller Interface in computer system 100, AHCI) under the situation, Basic Input or Output System (BIOS) 140 also can check into whether the initialization data of the base address of rank host controller interface (base address) is correct.And Basic Input or Output System (BIOS) 140 also can be sent to hard disk with instruction through the IO interface of hard disk, and then whether the function of the IO interface of affirmation hard disk is errorless.
In addition, because the local Advanced Programmable Interrupt Controllers APICs that central processing unit had (the Local Advanced Programmable Interrupt Controller of computer system 100, Local APCI) related data is to be stored in central processing unit, and central processing unit is not powered when computer system 100 is in holding state, therefore when operating, computer system 100 can normally be responsible for the Interrupt Process of central processing unit in order to ensure local Advanced Programmable Interrupt Controllers APICs, shown in step S370, Basic Input or Output System (BIOS) 140 will be checked the correctness of the initialization data of local Advanced Programmable Interrupt Controllers APICs.
In step S380, loading and open operation system are to finish the start flow process of computer system 100 at last.
In Fig. 2 and embodiment shown in Figure 3, when computer system 100 will be shut down, Basic Input or Output System (BIOS) 140 notice chipsets 120 and embedded controller 130 and then control computer system 100 enter holding state but not off-mode, and keep operating state data at that time.Because computer system 100 internal memory 110 when being in holding state still can continue to be powered, therefore operating state data wherein can be retained.When treating to open computer system 100 next time, just can utilize the operating state data that is retained in the internal memory 110 to reply the setting value of the buffer of chipset 120 fast, and as long as after the computer hardware to minority detects, but just load operation system is to finish boot program.
What must specify is, though be to be each step that example illustrates method for start-up and shutdown of the present invention with Fig. 3 in the above-described embodiments with the computer system shown in Figure 1A 100 collocation Fig. 2, the computer system 100 ' of Figure 1B and the computer system 100 of Fig. 1 C " also can execution graph 2 and each step shown in Figure 3.
Fig. 4 A is the calcspar of the computer system that illustrates according to another embodiment of the present invention.See also Fig. 4, computer system 400 comprises internal memory 110, chipset 120, embedded controller 130, Basic Input or Output System (BIOS) 140, and non-volatile storage 450.In the present embodiment, internal memory 110 is a DRAM (Dynamic Random Access Memory).Because chipset 120, embedded controller 130 have same or analogous function with the counterpart member of the computer system 100 shown in Basic Input or Output System (BIOS) 140 and Figure 1A, so do not repeat them here.
Fig. 4 B is the calcspar of the computer system that illustrates according to another embodiment of the present invention.The computer system 400 ' of Fig. 4 B is roughly similar to the framework of the computer system 400 of Fig. 4 A, difference therebetween is that central processing unit and the north bridge chips in the chipset 120 ' of computer system 400 ' is to be integrated into an integral chip 122, and in the chipset 120 of computer system 400,125 of central processing unit 121, north bridge chips 123 and South Bridge chips are member independently.
Fig. 4 C is the calcspar of the computer system that illustrates according to another embodiment of the present invention.Shown in Fig. 4 C, Basic Input or Output System (BIOS) 140 is not to be connected to chipset 120 shown in Fig. 4 A, 4B, and Basic Input or Output System (BIOS) 140 is to be connected to embedded controller 130 in the present embodiment.
And following the detailed process of the closedown method of computer system 400 will be described with Fig. 4 A and Fig. 5.Because step S510 to S550 shown in Figure 5 is same or similar with step S210 to S250 shown in Figure 2, so no longer explaining at this.
After making computer system 400 closely go into holding state, this moment, internal memory 110 can receive the power supply of power supply when seeing through step S510 to S550.Yet in order also to save power consumption further, in the present embodiment, shown in step S560, embedded controller 130 judges repeatedly whether the time that computer system 400 enters holding state arrives a default value.Wherein, default value for example is 24 hours, but the present invention is not limited this.
If judging computer systems 400 to enter holding state time is up, embedded controller 130 reaches default value, then shown in step S565, and embedded controller 130 computer system wakeups 400.And shown in step S570, Basic Input or Output System (BIOS) 140 is judged whether computer system 400 is waken up because computer system 400 enters holding state time is up and reaches default value.
If not, then shown in step S580, carry out normal in-cycle work program.
If then shown in step S585, Basic Input or Output System (BIOS) 140 writes to non-volatile storage 450 with the operating state data in the internal memory 110, and shown in step S590, the shutdown job procedure of computer system 400.That is Basic Input or Output System (BIOS) 140 notice embedded controllers 130 are with shut down computer by embedded Control 130 devices system 400 and power supply.So just can further reduce the consumption of power supply.And the former operating state data that is retained in the internal memory 110 can not disappear because being written into non-volatile storage 450 yet.
Fig. 6 is the detailed process of the starting-up method of the computer system 400 that illustrates according to another embodiment of the present invention.Because the step of Fig. 6 and Fig. 3 is roughly the same, thus below only describe with regard to both difference.
After starting the power supply of computer system 400 shown in the step S610, shown in step S613, Basic Input or Output System (BIOS) 140 checks in the internal memory 110 whether have operating state data.If not, then shown in step S615, judge whether non-volatile storage 450 has operating state data.
If not volatility storage device 450 has operating state data, represent that then the time that computer system 400 enters holding state has above default value.This moment, the operating state data that Basic Input or Output System (BIOS) 140 will be stored in the non-volatile storage 450 was re-loaded to internal memory 110 shown in step S620.
Then just shown in step S630 to S690, under the situation that hardware change does not take place, then utilize the operating state data in the internal memory 110 to start computer system 400 fast.
If judge that at step S613 internal memory 110 has had operating state data, or judge that at step S615 non-volatile storage 450 does not store operating state data, the starting-up method of the described computer system 400 of present embodiment is also with the action shown in the execution in step S630 to S690.
In the above-described embodiments, be to enter standby mode but not shutdown mode equally, and then operating state data is retained in internal memory 110 with control computer system 400 in the time will shutting down.Yet surpass default value in case enter the time of standby mode, do not have power supply also can preserve the non-volatile storage 450 of data, so reach the purpose of saving electric power even if just the operating state data in the internal memory 110 is changed to be stored to.
What must specify is, though be to be each step that example illustrates method for start-up and shutdown of the present invention with Fig. 6 in the above-described embodiments with the computer system shown in Fig. 4 A 400 collocation Fig. 5, the computer system 400 ' of Fig. 4 B and the computer system 400 of Fig. 4 C " also can execution graph 5 and each step shown in Figure 6.
In sum, computer system of the present invention and method for start-up and shutdown thereof are to enter holding state but not off-mode in the seasonal computer system of preparation shutdown, just operating state data at that time can be kept in the internal memory thus.Thereafter in the time will starting computer system once more, just can utilize the data that are kept in the internal memory to accelerate to start the speed of computer system.And when starting computer system, also can whether have the hardware change of generation to check to computer system.If be in holding state during hardware change once took place, then can be according to original start flow process, thus guarantee that computer system can normally be started.
