Embodiment
Describe in detail with reference to the accompanying drawings according to each embodiment of the present invention.Here, it should be noted that in the accompanying drawings, identical Reference numeral is given basically had ingredient identical or similar structures and function, and will omit being repeated in this description about them.
Below, with reference to Fig. 1 according to an embodiment of the invention terminal device is described.Fig. 1 is the according to an embodiment of the invention synoptic diagram of the structure of terminal device of diagram.
As shown in Figure 1, according to the terminal device of present embodiment (as, smart mobile phone, notebook and panel computer etc.) can comprise storer 11, internal memory 12 and processor 13.
Storer 11 can be realized by flash memory arbitrarily, and can store the various data that comprise operating system, user data and so on.According to embodiments of the invention, storer 11 storage the first firmware, the second firmware, the 3rd firmware, the first operating system (as, android) and the second operating system (as, Win 8) etc.
Here, the first firmware can to a part of element of terminal device (as, processor 13, internal memory 12 etc.) carry out initialization, and after the initialization of internal memory 12 is finished, the first operating system and the second operating system are imported in the internal memory 12.
In addition, the second firmware can be corresponding with the first operating system, and be used for loading the first operating system.For example, be in the situation of android in the first operating system, the second firmware can be the bootloader firmware.The 3rd firmware can be corresponding with the second operating system, and be used for loading the second operating system.For example, be in the situation of Win 8 in the second operating system, the second firmware can be the UEFI firmware.Here, the bootloader firmware that the second firmware and the 3rd firmware are not limited to exemplify (being used for android) and UEFI firmware (being used for Win 8) can also be other the firmwares that is used for mutually incompatible operating system.
Internal memory 12 can be realized by the RAM assembly of any type, and can be when powering up a part of data in the memory 11.Here, the access speed of obvious internal memory 12 is greater than the access speed of storer 11.
Processor 13 can be by realizations such as the processing unit of any type, microprocessing units.According to present embodiment, in the start-up course of the terminal device such as notebook, panel computer or smart mobile phone, in response to startup command (as, the user presses key or terminal device is restarted in selection), processor 13 at first carries out initialization based on the first firmware to the second storage unit.Then processor 13 is divided into the first storage area and the second storage area based on the first firmware with internal memory 12.Then processor 13 imports to the first operating system in the first storage area of internal memory 12, and the second operating system is imported in the second storage area of internal memory 12.Then, processor 13 loads one of the second firmware and the 3rd firmware to start the first or second corresponding operating system based on predetermined setting or input selection.
The below will describe the operation of carrying out according to the terminal device of the embodiment of the invention in detail.
For example, press after key or selection restart terminal device the user, processor 13 receives predetermined start-up command.After receiving start-up command, processor 13 begin to load the first firmware and based on this first firmware to a part of hardware of terminal device carry out initialization (as, processor 13 and internal memory 12).Here, because the initialization of internal memory 12 and processor 13 is known to those skilled in the art, therefore omitted the detailed description about aforesaid operations here.After based on the first firmware internal memory 12 being carried out initialization, can be from storer 11 to internal memory a part of data of 12 storages.According to embodiments of the invention, at this moment, processor 13 is divided into the first storage area and the second storage area based on the first firmware with internal memory 12.For example, the size of supposing internal memory 12 is 512MB, and processor 13 can be divided into internal memory 12 based on the first firmware two storage areas (the first storage area and the second storage area) of 256MB.In addition, the invention is not restricted to this, can as the case may be internal memory 12 be divided into unequal two storage areas.For example, if the first operating system takies more memory headroom, and the second operating system committed memory space is less, distribute more storage area as the first storage area then can for the first operating system, and distribute less storage area as the second storage area can for the second operating system.
Then, according to one embodiment of present invention, processor 13 can be based on the instruction in the first firmware, the first operating system is imported (writing) in the presumptive area of the first storage area of internal memory 12, and the second operating system is imported (writing) in the presumptive area of the second storage area of internal memory 12.For example, processor 13 can import to the first operating system in the first storage area in the zone that first address begins, and the second operating system can be imported in the second storage area in the zone that first address begins.Obviously, the first operating system and the second operating system can also be imported to respectively on any storage space in the first storage area and the second storage area.In addition, the residual memory space in the first storage area and the second storage area can use when the first operating system or the second operating system execution preset program.
The first operating system is being imported (writing) to the first storage area of internal memory 12, and the second operating system is imported (writing) after the second storage area of internal memory 12, and processor 13 can select to load the second firmware or the 3rd firmware based on the first firmware.For example, can dispose the parameter (for example, 0 corresponding to the first operating system, and 1 corresponding to the second operating system) of the first firmware so that processor 13 can determine to need to load the second firmware or the 3rd firmware.In addition, the first firmware can also be further carries out initialization to the display unit (not shown) of terminal device so that can be on terminal device demonstration information.In this case, processor 13 can show that at display unit choice menus is for user selection the first operating system or the second operating system based on the instruction of the first firmware.At this moment, processor 13 can determine user selection which firmware (or operating system) based on user's input.
If based on predetermined setting or user's input selection load in the situation of the second firmware, processor 13 loads these second firmwares, and loads the first operating system based on this second firmware.For example, be android in the first operating system, and the second firmware is in the situation of bootloader, if based on predetermined setting or user's input selection load in the situation of bootloader firmware, processor 13 loads the bootloader firmware, and loads android operating system based on the bootloader firmware.Here, the process that loads android operating system based on the bootloader firmware is known to those skilled in the art, has therefore omitted its detailed description here.
Here, it should be noted that the second firmware need to limit the second storage area.For example at processor 13 during based on the second firmware loads the first operating system, the second firmware defines the memory space that the first operating system can be used to the first operating system.In this case, it is invisible for the first operating system that the second firmware need to limit this second storage area, that is to say that the first operating system can not use the second storage area in the internal memory 12, and it only can use the first storage area in the internal memory 12.This is because if the second storage area for the first operating system visible, when then moving some program in the first operating system, may cover the data of the second operating system in the second storage area, may cause unusual appearance thus.Here, can notify the information of the distribution of relevant internal memory 12 to the second firmware by the first firmware, perhaps can in the second firmware, set in advance the information relevant with the scope of the first storage area.
In addition, if based on predetermined setting or user's input selection load in the situation of the 3rd firmware, processor 13 loads the 3rd firmware, and loads the second operating system based on the 3rd firmware.For example, be Win 8 in the second operating system, and the second firmware is in the situation of UEFI, if based on predetermined setting or user's input selection load in the situation of UEFI firmware, processor 13 loads this UEFI firmware, and loads Win 8 operating systems based on the UEFI firmware.
Similarly, the 3rd firmware need to limit the first storage area.For example at processor 13 during based on the 3rd firmware loads the second operating system, the 3rd firmware defines the memory space that the second operating system can be used to the second operating system.In this case, it is invisible for the second operating system that the 3rd firmware need to limit this first storage area, that is to say that the second operating system can not use the first storage area in the internal memory 12, and it only can use the second storage area in the internal memory 12.Here, can notify the information of the distribution of relevant internal memory 12 to the 3rd firmware by the first firmware, perhaps can in the 3rd firmware, set in advance the information relevant with the scope of the second storage area.
At processor 13 based on the second firmware loads the first operating system, or based on after the 3rd firmware loads the second operating system.Processor 13 this first operating system of operation or the second operating systems are so that the function that the user can provide based on the first operating system or the second operating system or the program of installing are thereon carried out predetermined task.
In addition, the embodiment that describes before the invention is not restricted to for example, can also replace the first firmware to finish the processing that loads the first operating system and the second operating system by the second firmware and the 3rd firmware.
Particularly, can in the second firmware (rather than first firmware), be provided for loading the instruction that the first operating system is imported to the presumptive area of the first storage area, and in the 3rd firmware (rather than first firmware), be provided for loading the instruction that the first operating system is imported to the presumptive area of the first storage area.
In this case, after processor 13 is divided into the first storage area and the second storage area based on the first firmware with internal memory 12,
In this case, if processor 13 based on the first firmware (as, with reference to predetermined setting or user's input) selected to load the second firmware, then processor 13 loads this second firmware, based on the second firmware that loads with the first operating system (as, android) import to the first storage area of internal memory 12, then load this first operating system from the first storage area, in order to start this first operating system.In addition, if processor 13 based on the first firmware (as, the setting that reference is predetermined or user's input) selection loading the 3rd firmware, then processor 13 based on the 3rd firmware that loads with the second operating system (as, Win 8) import to the second storage area of internal memory 12, then load this second operating system from the second storage area, in order to start this first operating system.。
Next, will the process of the operating system of switching terminal equipment be described.
For example, the first operating system (as, android) start after, the user may wish to use another operating system (as, Win 8).At this moment, in response to default switching command, processor 13 is preserved the current processor state of the first operating system, then the first operating system is switched to the second operating system.
Particularly, for example, default switching command can be the switching command in the menu that the first operating system provides, and perhaps can predetermined physics or virtual key be set at terminal device, and after the user presses this button, produce the operating system switching command and send to processor 13.Then, processor 13 in response to the switching command of operating system preserve processor 13 the current processor state (as, the data of each register in the processor, breakpoint of current process etc., memory address of process transfer data etc.).Here, current processor state can be stored in the storer 11.Then, preserve before whether processor 13 inspection exists with another operating system (as, Win 8) the relevant data of processor state.If there is no such data represent that then another operating system does not also start.At this moment, need to start another operating system (that is, the second operating system).In this case, processor 13 can start by three firmware corresponding with the second operating system this second operating system (as, Win 8).Here, because the second operating system has resided in the internal memory 12, therefore save the process that the second operating system is imported to internal memory 12, reduced thus the required time of switching of operating system.
In addition, if preserve before existing with another operating system (as, Win 8) the relevant data of processor state.Represent that then another operating system starts and moved.At this moment, do not need to restart another operating system (that is, the second operating system).In this case, the data that the processor state with another operating system (the second operating system) of preserving before processor 13 can read is relevant (as, the data of each register in the processor, breakpoint of current process etc., memory address of process transfer data etc.), and based on these data recover the before processor state when the second operating system is switched to the first operating system.Therefore, can when the first operating system is switched to the second operating system, recover original task or the program of in the second operating system, carrying out, terminal device is reduced to the state when the second operating system is switched.In this case, because therefore the relevant data of the processor state with another operating system (the second operating system) of preserving before only needing to read have greatly reduced the required time of switching operating system.
Similarly, the second operating system (as, Win 8) start after, and the user wish to use another operating system (as, android) time, in response to default switching command, processor 13 is preserved the current processor state of the second operating system, then the second operating system is switched to the first operating system.
Particularly, processor 13 in response to the switching command of operating system preserve processor 13 the current processor state (as, the data of each register in the processor, breakpoint of current process etc., memory address of process transfer data etc.).Then, the relevant data of the processor state with another operating system (the first operating system) of preservation before whether processor 13 checks and exist.If there is no such data represent that then another operating system does not also start.At this moment, need to start another operating system (that is, the first operating system).In this case, processor 13 can start by second firmware corresponding with the first operating system this first operating system (as, android).Here, because the first operating system has resided in the internal memory 12, therefore save the process that the first operating system is imported to internal memory 12, reduced thus the required time of switching of operating system.
In addition, if the relevant data of the processor state with another operating system (the first operating system) of preserving before existing.Represent that then another operating system starts and moved.At this moment, do not need to restart another operating system (the first operating system).In this case, the data that the processor state with another operating system (the first operating system) of preserving before processor 13 can read is relevant (as, the data of each register in the processor, breakpoint of current process etc., memory address of process transfer data etc.), and based on these data recover the before processor state when the first operating system is switched to the second operating system.Therefore, can when the second operating system is switched to the first operating system, recover original task or the program of in the first operating system, carrying out, terminal device is reduced to the state when the first operating system is switched.In this case, because the relevant data of the processor state with another operating system (the first operating system) of preserving before only needing to read, and do not need to restart the first operating system, therefore greatly reduced the required time of switching operating system.
Next, support the method that operating system is switched fast with reference to Fig. 2 description according to the terminal device that makes of the embodiment of the invention.Fig. 2 is that diagram is supported the process flow diagram of the method that operating system is switched fast according to the terminal device that makes of the embodiment of the invention.
As shown in Figure 2, at step S201, the startup command in response to default internally deposits into capable initialization based on the first firmware.
Particularly, after receiving predetermined startup command, processor 13 begin to load the first firmware and based on this first firmware to a part of hardware of terminal device carry out initialization (as, processor 13 and internal memory 12).
At step S202, internal memory is divided into the first storage area and the second storage area.
Particularly, after based on the first firmware internal memory 12 being carried out initialization, processor 13 is divided into the first storage area and the second storage area based on the first firmware with internal memory 12.For example, the size of supposing internal memory 12 is 512MB, and processor 13 can be divided into internal memory 12 based on the first firmware two storage areas (the first storage area and the second storage area) of 256MB.In addition, the invention is not restricted to this, can as the case may be internal memory 12 be divided into unequal two storage areas.For example, if the first operating system takies more memory headroom, and the second operating system committed memory space is less, distribute more storage area as the first storage area then can for the first operating system, and distribute less storage area as the second storage area can for the second operating system.
At step S203, the first operating system is imported in the first storage area, and the second operating system is imported in the second storage area.
Particularly, processor 13 can be based on the instruction in the first firmware, the first operating system is imported (writing) in the presumptive area of the first storage area of internal memory 12, and the second operating system is imported (writing) in the presumptive area of the second storage area of internal memory 12.For example, processor 13 can import to the first operating system in the first storage area in the zone that first address begins, and the second operating system can be imported in the second storage area in the zone that first address begins.Obviously, the first operating system and the second operating system can also be imported to respectively on any storage space in the first storage area and the second storage area.
At step S204, select to load one of the second firmware and the 3rd firmware.
Particularly, the first operating system is being imported (writing) to the first storage area of internal memory 12, and the second operating system is imported (writing) after the second storage area of internal memory 12, and processor 13 can select to load the second firmware or the 3rd firmware based on the first firmware.For example, can dispose the parameter (for example, 0 corresponding to the first operating system, and 1 corresponding to the second operating system) of the first firmware so that processor 13 can determine to need to load the second firmware or the 3rd firmware.In addition, the first firmware can also be further carries out initialization to the display unit (not shown) of terminal device so that can be on terminal device demonstration information.In this case, processor 13 can show that at display unit choice menus is for user selection the first operating system or the second operating system based on the instruction of the first firmware.At this moment, processor 13 can determine user selection which firmware (or operating system) based on user's input.
In addition, according to another embodiment of the invention, select to load the second firmware if method shown in Figure 2 can further include, then load the first operating system based on the second firmware from the first storage area; If perhaps select to load the 3rd firmware, then load the step of the second operating system based on the 3rd firmware from the second storage area.
Particularly, if based on predetermined setting or user's input selection load in the situation of the second firmware, processor 13 loads these second firmwares, and loads the first operating system based on this second firmware.For example, be android in the first operating system, and the second firmware is in the situation of bootloader, if based on predetermined setting or user's input selection load in the situation of bootloader firmware, processor 13 loads the bootloader firmware, and loads android operating system based on the bootloader firmware.
Here, during based on the second firmware loads the first operating system, the second firmware defines the memory space that the first operating system can be used to the first operating system at processor 13.In this case, it is invisible for the first operating system that the second firmware need to limit this second storage area, that is to say that the first operating system can not use the second storage area in the internal memory 12, and it only can use the first storage area in the internal memory 12.Here, can notify the information of the distribution of relevant internal memory 12 to the second firmware by the first firmware, perhaps can in the second firmware, set in advance the information relevant with the scope of the first storage area.
In addition, if based on predetermined setting or user's input selection load in the situation of the 3rd firmware, processor 13 loads the 3rd firmware, and loads the second operating system based on the 3rd firmware.For example, be Win 8 in the second operating system, and the second firmware is in the situation of UEFI, if based on predetermined setting or user's input selection load in the situation of UEFI firmware, processor 13 loads this UEFI firmware, and loads Win 8 operating systems based on the UEFI firmware.
Similarly, during based on the 3rd firmware loads the second operating system, the 3rd firmware defines the memory space that the second operating system can be used to the second operating system at processor 13.In this case, it is invisible for the second operating system that the 3rd firmware need to limit this first storage area.Here, can notify the information of the distribution of relevant internal memory 12 to the 3rd firmware by the first firmware, perhaps can in the 3rd firmware, set in advance the information relevant with the scope of the second storage area.
In addition, according to another embodiment of the invention, method shown in Figure 2 can further include the step of switching between the first operating system and the second operating system.
For example, behind the first os starting, in response to default switching command, processor 13 is preserved its current processor state, and the first operating system is switched to described the second operating system
Particularly, during terminal device moves the first operating system, processor 13 in response to the switching command of operating system preserve processor 13 the current processor state (as, the data of each register in the processor, breakpoint of current process etc., memory address of process transfer data etc.).Then, the relevant data of the processor state with another operating system (the second operating system) of preservation before whether processor 13 checks and exist.If there is no such data represent that then another operating system does not also start.At this moment, need to start another operating system (the second operating system).In this case, processor 13 can start by three firmware corresponding with the second operating system this second operating system (as, Win 8).Here, because the second operating system has resided in the internal memory 12, therefore save the process that the second operating system is imported to internal memory 12, reduced thus the required time of switching of operating system.
In addition, if the relevant data of the processor state with another operating system (the second operating system) of preserving before existing.Represent that then another operating system starts and moved.At this moment, do not need to restart another operating system (the second operating system).In this case, the data that the processor state with another operating system (the second operating system) of preserving before processor 13 can read is relevant (as, the data of each register in the processor, breakpoint of current process etc., memory address of process transfer data etc.), and based on these data recover the before processor state when the second operating system is switched to the first operating system.Therefore, can when the first operating system is switched to the second operating system, recover original task or the program of in the second operating system, carrying out, terminal device is reduced to the state when the second operating system is switched.
Similarly, behind the second os starting, in response to default switching command, processor 13 is preserved its current processor state, and the second operating system is switched to the first operating system.
Particularly, during terminal device moves the first operating system, processor 13 in response to the switching command of operating system preserve processor 13 the current processor state (as, the data of each register in the processor, breakpoint of current process etc., memory address of process transfer data etc.).Then, the relevant data of the processor state with another operating system (the first operating system) of preservation before whether processor 13 checks and exist.If there is no such data represent that then another operating system does not also start.At this moment, need to start another operating system (that is, the first operating system).In this case, processor 13 can start by second firmware corresponding with the first operating system this first operating system (as, android).Here, because the first operating system has resided in the internal memory 12, therefore save the process that the first operating system is imported to internal memory 12, reduced thus the required time of switching of operating system.
In addition, if the relevant data of the processor state with another operating system (the first operating system) of preserving before existing.Represent that then another operating system starts and moved.At this moment, do not need to restart another operating system (the first operating system).In this case, the data that the processor state with another operating system (the first operating system) of preserving before processor 13 can read is relevant (as, the data of each register in the processor, breakpoint of current process etc., memory address of process transfer data etc.), and based on these data recover the before processor state when the first operating system is switched to the second operating system.Therefore, can when the second operating system is switched to the first operating system, recover original task or the program of in the first operating system, carrying out, terminal device is reduced to the state when the first operating system is switched.In this case, because the relevant data of the processor state with another operating system (the first operating system) of preserving before only needing to read, and do not need to restart the first operating system, therefore greatly reduced the required time of switching operating system.
In addition, the invention is not restricted to the order that Fig. 2 describes, for example, step S204 can be before step S203.In this case, can be replaced by the second firmware and the 3rd firmware the processing of the first firmware completing steps S203.Namely, carry out respectively the processing that loads the first operating system and the second operating system by the second firmware and the 3rd firmware.
Particularly, can in the second firmware (rather than first firmware), be provided for loading the instruction that the first operating system is imported to the presumptive area of the first storage area, and in the 3rd firmware (rather than first firmware), be provided for loading the instruction that the first operating system is imported to the presumptive area of the first storage area.
In this case, based on the first firmware internal memory 12 is divided into the first storage area and the second storage area (step S202) afterwards at processor 13, processor selects to need to load the second firmware or the 3rd firmware (step S204) based on the first firmware.If processor 13 based on the first firmware (as, with reference to predetermined setting or user's input) selected to load the second firmware, then processor 13 loads this second firmware, based on the second firmware that loads with the first operating system (as, android) import to the first storage area of internal memory 12, then load this first operating system from the first storage area, in order to start this first operating system.In addition, if processor 13 based on the first firmware (as, the setting that reference is predetermined or user's input) selection loading the 3rd firmware, then processor 13 based on the 3rd firmware that loads with the second operating system (as, Win 8) import to the second storage area of internal memory 12, then load this second operating system from the second storage area, in order to start this first operating system.
By above-mentioned configuration, by the first firmware the first operating system and the second operating system are imported in the second storage unit (internal memory) in advance, then start the first operating system and the second operating system based on the second firmware corresponding with the first operating system and the second operating system and the 3rd firmware, can make terminal device support neatly multiple incompatible operating system.In addition, because the first operating system and the second operating system have resided in the second storage unit (internal memory), therefore in the process of switching operating system, save the process that loads another operating system, shortened thus the required time of switching operating system.
Describe each embodiment of the present invention in the above in detail.Yet, it should be appreciated by those skilled in the art that without departing from the principles and spirit of the present invention, can carry out various modifications to these embodiment, combination or sub-portfolio, and such modification should fall within the scope of the present invention.
