The characteristics of nonvolatile memory 101, can save for data after power down, and in order to convenient for management, operating system can be incited somebody to action Nonvolatile memory 101 is divided into multiple subregions, different subregions for storing different data, including user data and Unique System mirror image of operating system etc..In order to manage and read and write conveniently, these subregions can be formatted as specific file system EXT4 file system can be used in system, such as the terminal based on linux system.

Computer program instructions are stored in DDR 103, are referred in these computer program instructions including operating system program It enables.By taking operating system program instructs as an example, is executed in run mode with system process is basic execution entity, may include The types such as consumer process, kernel process.

Based on above-mentioned terminal, after exchange powers on, during the system startup process, central processing unit 102 will be stored in non-easy Unique System mirror image in the property lost memory is loaded into Double Data Rate synchronous DRAM 103.

The Unique System mirror image being stored in nonvolatile memory 101 is used to specifically describe the operating status of the system, After exchange powers on, system process is according to the operating status of the data recovery system in the Unique System mirror image.And unique system Data in system mirror image are only updated before the AC dump after machine system upgrading or aerial downloading upgrading, specifically, by kernel Scheduling process in process sends mirror image production instruction to update the data in the Unique System mirror image.

As shown in Fig. 2, a kind of flow chart of the system start method of intelligent TV set provided by the embodiments of the present application, the stream Journey can be realized by the system starting device of intelligent TV set.

This method comprises:

S201: freeze the system process for accessing the first subregion in memory;Wherein, system process includes consumer process And kernel process, consumer process include data synchronizing process.

In practical application, it can comprise the further steps of: before above-mentioned steps after exchange powers on, the startup program of system is drawn In house software is led to initialize hardware device;After the completion of hardware device initialization, kernel starting simultaneously carries out each subsystem Initialization, to take the hardware environment of system to a proper states.

In S201, for the system process for the first subregion being possible in access memory, it can be freezed.Using Traditional mirror image loading method, after load Unique System is mirrored to memory, the subregion that sets in memory is read-write point Area, the data in the subregion are possible to and the data in nonvolatile memory in corresponding region mismatch.In the memory Setting subregion may include but be not limited to the Userdata subregion in the subregions, such as linux system such as user data subregion (for depositing Store up user data) and Tvconfig subregion (being used for storage device configurations information).

For convenience of description, the unmatched memory partitioning of data will be caused to become because carrying out the load of Unique System mirror image here First subregion, by the subregion on nonvolatile memory corresponding with the first subregion, (i.e. carry is in the non-volatile of the first subregion Memory partition) it is known as the second subregion.First subregion and the second subregion are read-write subregion.First subregion and the second subregion can To be respectively one or more subregions.For example, the first subregion in memory may include Userdata points by taking linux system as an example Area's (for storing user data) and Tvconfig subregion (being used for storage device configurations information), correspondingly, non-volatile memories The second subregion in device includes Userdata subregion and Tvconfig subregion.

The state of system process mainly include executable state, can disrupted sleep state, can not disrupted sleep state, pause State and exit state.In S201, the system process of the first subregion in memory can may be accessed by being provided with State be can not disrupted sleep state, freeze to be possible to the kernel process and consumer process of the first subregion in access memory, than Such as send scheduling process, the data synchronizing process of the production instruction of Unique System mirror image.Due to these consumer process and kernel into Journey is frozen before the load of Unique System mirror image, in this way in Unique System mirror image loading procedure, these frozen users into Journey and kernel process are unable to run, thus can be to avoid in Unique System mirror image loading procedure, these consumer process and kernel After process discovery load Unique System is mirrored to memory, the data of the data of memory and storage in the nonvolatile memory are not The problem of matching, system caused not start normally.

S202: process of the triggering for the load of Unique System mirror image, so that this is used for the process of Unique System mirror image load Unique System mirror image is read from nonvolatile memory, and the Unique System mirror image is loaded into memory.

In some embodiments, to save memory space, Unique System mirror image is stored in non-volatile deposit after overcompression Reservoir, in response to this, in S202, the process reading for the load of Unique System mirror image is stored in nonvolatile memory The compressed Unique System mirror image of storage, decompresses the Unique System mirror image of the compression, and by unique system after decompression The data of system mirror image are loaded into memory.

S203: defrosting data synchronizing process so that data synchronizing process by nonvolatile memory with described first point Data in corresponding second subregion in area are synchronized to the first subregion.

Optionally, it can be used and first unload again again the mode of carry and realize that data are synchronous.It is loaded by Unique System mirror image During memory, need the respective partition subregion in nonvolatile memory being mounted in memory.Such as it will be non-easy User data subregion in the property lost memory is mounted to the user data subregion in memory.For adding because carrying out Unique System mirror image The subregion and corresponding memory partitioning of the unmatched nonvolatile memory of data are carried and caused, can be weighed again by first unloading The mode of new carry realizes that data are synchronous.

First unload again that the mode of carry realizes the synchronous process of data again, it may include: data synchronizing process will be non-volatile Property memory the second subregion unloaded from the first subregion of memory, and the second subregion of nonvolatile memory is mounted to again First subregion of memory carries out carry, so that the data in the second subregion are synchronized to the first subregion.

S204: after the data in nonvolatile memory are synchronized to memory by data synchronizing process, thaw frozen its Its system process.

It optionally, can be by the way that set the state of the other consumer process being frozen and frozen kernel process to can Execution state, with these system process that thaw.It include scheduling process in the kernel process being defrosted, which can be to it Its system process is scheduled, to complete subsequent system starting process.

Since system is based on Unique System image starting, and Unique System mirror image is the scheduling process in kernel process The lower completion of control, therefore after the data in the second subregion are all synchronized to the first subregion, which is defrosted first.After And the scheduling process sends instructions to frozen other consumer process and frozen other kernel process, so that frozen Other consumer process and frozen other kernel process continue process, to complete system starting.

According to above-mentioned process, due to freezing to be possible to access the first subregion in memory before the load of Unique System mirror image Consumer process and kernel process, in this way in Unique System mirror image loading procedure, these frozen consumer process and kernel into Journey is unable to run, thus is avoided in Unique System mirror image loading procedure, these consumer process and kernel process find this only The data of the data and storage of memory in the nonvolatile memory mismatch where the load of one system image, cause system can not The problem of normal starting.After Unique System mirror image is loaded into memory, data synchronizing process in defrosting consumer process, so that should The data stored in the nonvolatile memory are synchronized to the memory by data synchronizing process, then by it is frozen it is other into Cheng Jinhang thaws, since data synchronizing process carries out the data in the data and memory that store in nonvolatile memory It is synchronous, when the process that these are defrosted carries out data access, be not in the data that are stored in nonvolatile memory with it is interior The unmatched problem of data in depositing, and then can start to avoid system and fail.

In order to be more clearly understood that the embodiment of the present application, below by taking the intelligent TV set based on android system as an example, retouch State system starting process.

Wherein, the subregion in the nonvolatile memory of intelligent TV set includes:

System subregion (system partitioning) is used for storage system operating status mirror image;

Userdata subregion (user data subregion), for storing user data, such as the application journey of storage system installation Sequence;

Each subsystem initialization of verification in S302:Linux.

After the completion of hardware device initialization, linux kernel carries out initial work to each subsystem, which includes interior Deposit management subsystem, power management subsystem, universal serial bus subsystem and input subsystem etc..

S303: freezing system process.

In linux system, in order to limit the access ability between different processes, prevent them from arbitrarily obtaining memory partitioning In data or obtain the data of peripheral equipment, therefore a running state of a process is divided into kernel state and User space.Wherein, locate When kernel state, all data in the accessible memory of central processing unit, including peripheral equipment, such as non-volatile memories One program can also be switched to another program by device, network interface card etc., in this case, central processing unit;When in User space, The partial data in access memory that central processing unit can only be limited, and do not allow to access peripheral equipment.

In S303, the later period is initialized in each subsystem, system process is in kernel state, by calling freeze- The state of the system process of the subregion of memory is not where processes function would be possible to access after unique STD image decompressing Can disrupted sleep state, in this case, frozen system process will not be scheduled.Wherein, frozen system process includes Consumer process and kernel process include the Histd process synchronous for data in consumer process, include for sending out in kernel process Send the StdService process of unique STD mirror image production instruction.

S304: process of the starting for the load of unique STD mirror image.

In above-mentioned steps, process of the starting for the load of unique STD mirror image.So that the process reads non-volatile memories Unique STD mirror image of device is loaded into interior Booting subregion, decompresses to compressed Unique System mirror image, and It with page (for example size is 4K) is that unit copies in the memory by the Unique System mirror image data after decompression.

S305: defrosting Histd process.So that in the data in nonvolatile memory are synchronized to by the Histd process It deposits.

By taking user data Userdata as an example, the process for the load of unique STD mirror image will be in unique STD mirror image After Userdata is copied in memory where unique STD mirror image in the Userdata subregion of subregion, and by nonvolatile memory In Userdata subregion be mounted to the Userdata subregion of subregion where unique STD mirror image in memory.Histd process is defrosted Afterwards, Histd process is by the load shedding where STD mirror image unique in memory in the Userdata subregion of subregion, and again should Userdata subregion in nonvolatile memory is mounted to the Userdata subregion of subregion where unique STD mirror image in memory On, i.e., it is operated by the loading and unloading of subregion, completes the scanning to variance data, copies, so that in nonvolatile memory Userdata subregion in data be synchronized to the Userdata subregion of subregion where unique STD mirror image in memory.

S306: judge whether data synchronization is completed.If being completed, execute S307, if do not complete, wait Histd into It is synchronous that journey completes data.

S307: defrosting StdService process.After the data in memory in Userdata subregion synchronously complete, StdService process is defrosted first.

The frozen other system process of S308:StdService process defrosting.StdService process is to frozen Other system process send instruction, and thaw frozen other system process, and triggers its start-up operation.
