Below, with reference to Fig. 1, the terminal device according to the embodiment of the present invention is described.Fig. 1 is the schematic diagram of diagram according to the structure of the terminal device of the embodiment of the present invention.
As shown in Figure 1, the first storage unit 11, second storage unit 12, access controller 13 and processing unit 14 is comprised according to the terminal device of the embodiment of the present invention.
First storage unit 11 can store the various data comprising operating system, user data and so on, and can be realized by any type hard disk or flash memory.
Second storage unit 12 can be realized by the internal storage location of any type, and can partial data in speed buffering first storage unit 11.Here, the access speed of the second storage unit 12 is far longer than the access speed of the first storage unit.
Access controller 13 can be realized by dma controller.Here, because the 26S Proteasome Structure and Function of the access controller 13 of such as dma controller and so on is known to those skilled in the art, only it is simply described here.Access controller 13 can be connected with the first storage unit 11 and the second storage unit 12, and the data in the first storage unit 11 can be written in the second storage unit 12 independent of processing unit 14.Here it is to be noted that it access controller 13 carries out the read/write of data independent of processing unit 14.Namely, when processing unit 14 carries out predetermined process, data can be written to the second storage unit 12 from the first storage unit 11 by access controller 13 concurrently.
Processing unit 14 can by realizations such as the processing unit of any type, microprocessing units.Usually, in the start-up course of the such as terminal device of desktop computer, notebook or panel computer and so on, in response to startup command (as, user presses key or terminal device is restarted in selection), first processing unit 14 carries out initialization to self, then initialization is carried out based on preset program (e.g., BIOS) each element (comprising the first storage unit 11, second storage unit 12, access controller 13) to terminal device inside.After each element of processing unit 14 pairs of terminal device inside carries out initialization, processing unit carries out the startup of operating system based on os starting program (e.g., OSloader).In the prior art, after the initialization of the initialized element of all needs of terminal device inside all completes, processing unit 14 just starts load operation startup procedure, and based on this os starting program, the various startup files (e.g., SMSS) starting the operating system required are written to the second storage unit 12 and start to start the operating system.But, according to the present invention, can be configured the preset program of such as BIOS and so on, make after processing unit 14 carries out initialization in response to startup command to the first storage unit 11, second storage unit 12 and access controller 13, and before processing unit 14 starts the operating system based on os starting program, by access controller 13, the data of such as various startup file or secure data and so on are written to the second storage unit 12 from the first storage unit 11.
The operation performed according to the terminal device of the embodiment of the present invention will be described in detail below.
Such as, after user presses key or terminal device is restarted in selection, processing unit 14 receives predetermined start-up command, first completes the initialization of self, and starts to carry out initialization to each element in terminal device.Usually; based on the setting of BIOS; processing unit 14 usually can first to relatively at a high speed element (as; dma controller or internal memory) carry out initialization; then initialization is carried out to element (e.g., hard disk, flash memory, USB interface, mouse, keyboard interface, display etc.) relatively at a slow speed.In this case, owing to first carrying out initialization to element relatively at a high speed, then initialization is carried out to element relatively at a slow speed, therefore, obviously after processing unit 14 carries out initialization to the first storage unit 11 (e.g., hard disk, flash memory), processing unit 14 has completed the initial work of the second storage unit 12 (e.g., internal memory) and access controller 13.
According to embodiments of the invention, after processing unit 14 carries out initialization to the first storage unit 11, second storage unit 12 and access controller 13, and processing unit 14 to not yet initialized residue element (as, USB interface, mouse, keyboard interface, display etc.) carry out initialization during, tentation data (e.g., the startup file of operating system) can be written to the second storage unit 12 from the first storage unit 11 by access controller 13.
According to embodiments of the invention, tentation data be each startup file needed for os starting (as, SMSS etc.) when, before above-mentioned startup file is written to the second storage unit 12 from the first storage unit 11 by access controller 13, the address information of startup file in the first storage unit 11 and scope (e.g., the start address of startup file and length) can be sent to access controller 13 by processing unit 14.When access controller 13 obtains with the address information of startup file in the first storage unit 11 and scope, access controller 13 reads startup file based on obtained address information and scope from the first storage unit 11, and is written in the second storage unit 12 by read startup file.Particularly, can store address and the scope of each startup file, and configure bios program in bios program, processing unit 14 can be judged, and whether the initialization of the first storage unit 11, second storage unit 12 and access controller 13 completes.If the initialization of the first storage unit 11, second storage unit 12 and access controller 13 completes, then before each startup file is written to the second storage unit 12 from the first storage unit 11 by access controller 13, the address of each stored startup file and scope can be sent to access controller 13 by processing unit 14, access controller 13 reads startup file based on obtained address information and scope from the first storage unit 11 thus, and is written in the second storage unit 12 by read startup file.As long as here it is to be noted that it processing unit 14 is known the address of each stored startup file and scope, the memory address of each startup file and scope can be discrete or continuous print.
In addition, when startup file is written to the second storage unit 12 from the first storage unit 11 by access controller 13, the mapping relations between the address of startup file in the second storage unit 12 and the address in the first storage unit 11 can also be stored in address mapping table by access controller 13.Such as, this address mapping table be expression first storage unit (as, hard disk) mapping table of corresponding relation between the address of data in 11 and the address of this data in the second storage unit (e.g., internal memory) 12, and be generally held in the first storage unit 11.
Then, after the initialized element of all needs in processing unit 14 pairs of terminal devices has carried out initialization, before starting the operating system, processing unit 14 can be monitored access controller 13 and whether complete operation startup file being written to the second storage unit 12 from the first storage unit 11.If access controller 13 completes aforesaid operations, then processing unit 14 can operation startup procedure (OSloader) to start the operating system.Otherwise processing unit 14 can be waited for until access controller 13 completes aforesaid operations.In this case, BIOS can be set to adjust the initialization order of each element of terminal device.Such as, can after the initialization of the second storage unit 12 and access controller 13 initialization immediately first storage unit 11, and then initialization other relative high speed or element at a slow speed, make access controller 13 can have the more time and startup file be written to the second storage unit 12 from the first storage unit 11.
In addition, after the initialized element of all needs in processing unit 14 pairs of terminal devices has carried out initialization, whether processing unit 14 can not be monitored access controller 13 and complete startup file is written to the second storage unit 12 and direct operation startup procedure from the first storage unit 11.Such as, the memory location of each startup file in the first storage unit 11 can be configured.Such as, each startup file used when processing unit 14 can be started the operating system based on os starting program is stored sequentially in the first storage unit 11, and makes the memory location of the startup file used at first in the foremost of the memory location of each startup file.Here, when the first storage unit 11 is hard disk, each startup file is stored sequentially in the first storage unit 11 time (reducing number of times and the address-time of the magnetic head redirect of hard disk) that can reduce and read above-mentioned startup file from the first storage unit 11, accelerates the speed above-mentioned startup file being written to the second storage unit 12 from the first storage unit 11 thus.In addition, processing unit 14 by the address information of each startup file in the first storage unit 11 and scope (as, the start address of startup file and length) send to access controller 13, and when access controller 13 reads startup file based on obtained address information and scope from the first storage unit 11, the startup file used at first during os starting can be written to the second storage unit 12 from the first storage unit 11 by access controller 13 in advance.In this case, when when operation startup procedure is to start the operating system after completing the initialization needing to carry out initialized all elements for processing unit 14, the startup file used at first can be read from the second storage unit 12.Meanwhile, access controller 13 continues remaining startup file to be written to the second storage unit 12 from the first storage unit 11.
To processing unit 14 operation startup procedure will be described in come the operation of start up system below.
Such as, complete startup file from after the first storage unit 11 is written to the second storage unit 12 at wait access controller 13, or after completing the initialization needing to carry out initialized all elements, processing unit 14 operation startup procedure (e.g., OSloader) starts the operating system.In this case, os starting program needs to start the operating system to load each startup file, and is provided for the reading command reading these startup files.Here, this reading command comprises the address of the startup file that will read.Now, processing unit 14 can obtain reading command for reading startup file from the first storage unit 11 from os starting program.Now, processing unit 14 tackles this reading command, and revises described reading command to point to the startup file be stored in the second storage unit 12 based on address mapping table.Particularly, processing unit 14 can obtain the address of startup file in the second storage unit 12 with reference to the content in address mapping table, and based on this address amendment reading order.Then, processing unit 14 can obtain this startup file based on revised reading command from the second storage unit 12.
By above-mentioned configuration, after processing unit 14 carries out initialization to the first storage unit 11, second storage unit 12 and access controller 13, and during other element in processing unit 14 pairs of terminal devices carries out initialization, utilize access controller 13 in advance the startup file needed for os starting to be written to the second storage unit 12 from the first storage unit 11.Then, when processing unit 14 operation startup procedure carrys out start up system, amendment is used for reading the reading command of startup file to point to the corresponding startup file be stored in the second storage unit 12 from the first storage unit 11.Here, the access speed due to the second storage unit 12 is far longer than the access speed of the first storage unit 11, and the time of therefore reading startup file from the second storage unit 12 is less than the time of reading startup file from the first storage unit 11.In this case, greatly can save the time needed for os starting of terminal device, thus the use sense enhancing user is subject to.
In addition, the invention is not restricted to the situation that tentation data is startup file.Such as, tentation data can also be the secure data of virus base file and so on and the significant data of user.Similar to the previous description, after processing unit 14 carries out initialization to the first storage unit 11, second storage unit 12 and access controller 13, and processing unit 14 to not yet initialized residue element (as, USB interface, mouse, keyboard interface, display etc.) carry out initialization during, the significant data of secure data and user can be written to the second storage unit 12 from the first storage unit 11 by access controller 13.In this case, after processing unit 14 completes in terminal device and needs to carry out initialized all elements, processing unit 14 can before operation startup procedure, security of operation program also reads the secure data be stored in the second storage unit 12, and utilizes this secure data to carry out the operation such as virus or wooden horse killing to the significant data of user.Like this, before the os starting of terminal device, can guarantee that the significant data stored in terminal device is not subject to the infringement of specific virus (e.g., CIH) or wooden horse, thereby increase the stability of system.Meanwhile, owing to reading the significant data of secure data and user from the second storage unit 12, the time of security of operation program can therefore be saved.
In addition, the present invention is not limited thereto, processing unit 14 to not yet initialized residue element (as, USB interface, mouse, keyboard interface, display etc.) carry out initialization during, can also secure data and startup file be written to the second storage unit 12 from the first storage unit 11, and before processing unit 14 operation startup procedure, utilize the secure data in the second storage unit 12 to check security of the startup file in the second storage unit 12 etc.
Below, with reference to Fig. 2, the method started the operating system according to the embodiment of the present invention is described.Fig. 2 is the process flow diagram of diagram according to the method started the operating system of the embodiment of the present invention.

Such as, according to one embodiment of present invention, after processing unit 14 carries out initialization to the first storage unit 11, second storage unit 12, and processing unit 14 to not yet initialized residue element (as, USB interface, mouse, keyboard interface, display etc.) carry out initialization during, tentation data (e.g., the startup file of operating system or secure data) can be written to the second storage unit 12 from the first storage unit 11 by access controller 13.
Particularly, tentation data be each startup file needed for os starting (as, SMSS etc.) when, before above-mentioned startup file is written to the second storage unit 12 from the first storage unit 11 by access controller 13, the address information of startup file in the first storage unit 11 and scope (e.g., the start address of startup file and length) are sent to access controller 13 by processing unit 14.Then, access controller 13 reads startup file based on obtained address information and scope from the first storage unit 11, and is written in the second storage unit 12 by read startup file.
In addition, when startup file is written to the second storage unit 12 from the first storage unit 11 by access controller 13, the mapping relations between the address of startup file in the second storage unit 12 and the address in the first storage unit 11 can also be stored in address mapping table by access controller 13.Such as, this address mapping table be expression first storage unit (as, hard disk) mapping table of corresponding relation between the address of data in 11 and the address of this data in the second storage unit (e.g., internal memory) 12, and be generally held in the first storage unit 11.
Then, after the initialized element of all needs in processing unit 14 pairs of terminal devices has carried out initialization, before starting the operating system, processing unit 14 can also be monitored access controller 13 and whether complete operation startup file being written to the second storage unit 12 from the first storage unit 11.If access controller 13 completes aforesaid operations, then processing unit 14 can operation startup procedure (OSloader) to start the operating system.Otherwise processing unit 14 can be waited for until access controller 13 completes aforesaid operations.Here, according to one embodiment of present invention, BIOS can be set to adjust the initialization order of each element of terminal device.Such as, can after the initialization of the second storage unit 12 and access controller 13 initialization immediately first storage unit 11, and then initialization other relative high speed or element at a slow speed, make access controller 13 can have the more time and startup file be written to the second storage unit 12 from the first storage unit 11.
