In some instances, methods, means, elements and circuits that are well known to those skilled in the art have not been described in detail so as not to obscure the present disclosure.
In the related art, the switching process of the operating system in the same electronic device is too complex. In view of this, an embodiment of the present disclosure provides an operating system switching method, which may store, when a first operating system of the at least two operating systems is loaded into a first storage space in the internal memory and processes to-be-processed data corresponding to the first operating system through the processing core, a current working parameter of the processing core as a first parameter in the internal memory and reset the processing core when a switching instruction corresponding to a second operating system of the at least two operating systems is received. And then allocating a second storage space in the internal memory for the second operating system. And finally, loading a second operating system in the external memory to the second memory space, and processing the data to be processed corresponding to the second operating system through the processing core. According to the switching method provided by the embodiment of the disclosure, the operating system can be switched in one key mode through the switching instruction corresponding to the operating system, and the switching process of the operating system can be simplified. In addition, the embodiment of the disclosure can realize dormancy and reload of the operating systems during switching by storing the current working parameters of the processing cores, which is beneficial to realizing multiple switching among the operating systems.
Referring to fig. 1, fig. 1 is a flowchart illustrating a switching method of operating systems according to an embodiment of the present disclosure, as shown in fig. 1, the switching method is applied to an electronic device, the electronic device includes an external memory, an internal memory, and a processing core, the external memory stores at least two operating systems, and the switching method includes: step S100, during the period when a first operating system of the at least two operating systems is loaded into a first storage space in the internal memory and processes to-be-processed data corresponding to the first operating system through the processing core, and when a switching instruction corresponding to a second operating system of the at least two operating systems is received, saving a current working parameter of the processing core as a first parameter in the internal memory, and resetting the processing core. For example, the external memory may be partitioned, for example, into a C disk, a D disk, and the like, and then each operating system may be stored in a different partition, respectively, to implement isolation of the operating systems. Different operating systems may also be saved directly to different external memories in one example. The type of the operating system is not limited in this disclosure, and the operating system may be called by an electronic device, for example: if the electronic device is a computer, the operating system may include: linux, windows, UNIX, apple, etc., and if the electronic device is a mobile terminal, the operating system may include Windows, android, apple, hong meng, etc. It should be understood that the above-mentioned switching of the operating systems may also be switching of different versions for the same kind of operating systems, for example: from Windows7 to Windows10. The switching instruction may be any instruction recognizable by the electronic device, and in one example, each switching instruction may correspond to a unique operating system, so that the electronic device can know the operating system to be switched by the user. In another example, if two operating systems are shared, the operating systems can be switched by using the same key, and the embodiment of the present disclosure is not limited herein, and a developer can set the operating systems according to actual situations. In a possible implementation, the switching instruction may include: any one of a preset key instruction, a preset combination of key instructions, and a preset voice instruction. Illustratively, the key instruction may be a key instruction in a keyboard, a mouse, a virtual keyboard, or a combination thereof. The voice instruction may be acquired through a microphone in the electronic device, and then the voice instruction is recognized through a voice recognition technology in the related technology and is matched with the preset voice instruction, and in the case of successful matching, the current operating system may be switched to the operating system corresponding to the preset voice instruction. Illustratively, the above data to be processed may be represented as: based on data used by applications run by the operating system or data related to the running of the operating system, etc. The internal memory (or internal memory) may be used to temporarily store instructions and data being used by a Central Processing Unit (CPU), and has a faster access speed than the external memory, and does not store information after power-off, for example: caching, shipping, etc. The external memory (or called external memory) is used to store information that is not needed to be used immediately, has a larger capacity than the internal memory, and can still store information after power off, and is a "nonvolatile" memory, for example: hard disks, floppy disks, optical disks, etc. For example, the current operating parameters of the processing core may be represented as values held in registers in the processing core, and resetting the processing core may be represented as resetting registers in the processing core.
Step S200, allocating a second storage space in the internal memory to the second operating system. Wherein the storage addresses of the first storage space and the second storage space are not overlapped. The embodiment of the present disclosure does not limit the allocation manner of the second storage space, and the second operating system may be loaded to the second storage space. In one example, each operating system may be allocated a fixed memory space, i.e., the memory addresses that each operating system may occupy in the internal memory after each power-down, power-up are the same. In another example, each operating system may also be allocated a fixed size of a storage space, that is, the maximum space that each operating system may occupy in the internal memory after powering down and powering up is the same, and storage addresses may be different, which is not limited herein.
Step S300, loading a second operating system in the external memory to the second storage space, and processing the to-be-processed data corresponding to the second operating system through the processing core.
In a possible implementation, the handover method further includes: after the electronic device is powered on, one of the at least two operating systems is determined. For example, the operating system may be an operating system that is started by default after the electronic device is powered on, and may be set by a developer in a factory, or may be set by a user on a user interface in the electronic device after the operating system is started, which is not limited herein. The memory space in the internal memory is then allocated for the determined operating system. And finally, loading the determined operating system in the external memory to the storage space, and processing the data to be processed corresponding to the determined operating system through the processing core.
In a possible implementation, the handover method further includes: and determining the size of the storage space allocated by each operating system in the internal storage according to the total number of the operating systems in the external storage and/or the system type of each operating system. Wherein the system category is used to represent usage of the operating system. For example, a developer or a user may store the total number of operating systems and/or the system class of each operating system in the external memory, and then equally or weighted allocate the storage space in the internal memory according to the total number. In one example, each operating system may correspond to a system class that may be set by a user for a primary purpose for each system, such as: the system type of the Linux system can be set to work, the system type of the Windows system can be set to entertainment, in an actual application scene, the internal storage space occupied by the entertainment application program is generally larger, and in this case, a larger internal storage space can be allocated to the entertainment operating system for the system type. In one example, the system category may be set by a user to meet the actual needs of the user. For example, the step of allocating the storage space may be performed each time the electronic device is powered on, or may be performed when the total number of the operating systems changes and/or the system types of the operating systems change, and the embodiments of the present disclosure are not limited herein.
In a possible implementation, the handover method further includes: a shutdown instruction for a third operating system of the at least two operating systems is received. Illustratively, the shutdown instruction is used to indicate that the third operating system is no longer used in the working process of the electronic device. In an example, the third operating system may be any one of the at least two operating systems, or may be the first operating system and the second operating system, and embodiments of the present disclosure are not limited herein. And then deleting the data stored in the corresponding third storage space in the internal memory by the third operating system, and allocating the third storage space to other operating systems except the third operating system in the at least two operating systems. For example, the third storage space may be equally divided into other operating systems, or assigned with a weight according to a system type corresponding to each operating system in the other operating systems, and the embodiment of the present disclosure is not limited herein. The embodiment of the disclosure can save the storage space of the internal memory by releasing the currently unnecessary operating system, and is beneficial to supporting other operating systems to run the application programs which need to occupy larger storage space. In an example, a user may also have a need to use the third operating system, so the embodiment of the present disclosure allows the user to perform self-setting on this need, and the electronic device may not allocate the storage space of the internal memory to the third operating system in the boot stage even when the third operating system is not needed. It should be understood that this step may occur during an initial stage of powering on the electronic device, and may also occur during an operating stage of the electronic device, and the embodiments of the present disclosure are not limited thereto.
In combination with the actual application scenario, the electronic device may be represented as a computer in the related art, and a Windows system and a Linux system may be respectively stored in different hard disks of the computer. On the partition of the physical memory, half of the physical memory is allocated to the Windows System, and the other half of the physical memory is allocated to the Linux System (which may be implemented by a BIOS or a Basic Input Output System), and a special physical memory may be reserved for caching the context of the Windows System and the Linux System (for example, the current operating parameters of the CPU). Then the electronic device enters the desktop of Windows, when the user needs to switch the operating system, a specific keyboard combination key can be input (the electronic device can obtain the CPU authority of the whole operating system through the highest level interruption, then jump to the related switching function to realize the switching of the operating system), the drive is informed, the started hard disk is modified through the BIOS, the power is stored in the DDR (Double Data Rate), the CPU context (or called current working parameter) is stored, and then the CPU is reset. The BIOS is guided into the Linux system through the hard disk of the Linux system, and the other half of the physical address is reported to the Linux system for use. The Linux system enters the desktop, and under the condition that a user needs to switch the operating system, a specific keyboard combination key can be input again to switch to the Windows system, the page table of the memory and the context of the CPU are switched, the Windows awakening process is entered, and the Windows restores the desktop.
It is understood that the above-mentioned method embodiments of the present disclosure can be combined with each other to form a combined embodiment without departing from the logic of the principle, which is limited by the space, and the detailed description of the present disclosure is omitted. Those skilled in the art will appreciate that in the above methods of the specific embodiments, the specific order of execution of the steps should be determined by their function and possibly their inherent logic.
