Fig. 1 shows the flow chart of the method for electronic device system Acceleration of starting according to an embodiment of the invention.
As shown in figure 1, methods described 100 starts from step S110, in step s 110, when electronic equipment starts, create
Pre-read thread, is determined with starting to be read from the disk of electronic equipment using pre-read thread for the advance of os starting
The pre-reading data of justice.
Embodiments in accordance with the present invention, can in computer starting, BOOT drive initialization when, obtained from registration table
Take the information of pre-defined pre-reading data（The offset address of such as these data）, and pre-read thread is created, in magnetic
After disc apparatus are added well, using the pre-read thread according to the information of the pre-reading data got from registration table, start from magnetic
The pre-defined pre-reading data is read in disk.Because pre-read thread and operating system are concurrently run, and pre-read
Line taking journey is prior to operating system, therefore the os starting data to be read can as early as possible by pre-read thread
Read out.
Alternatively, the disk can be any kind of magnetic storage for realizing store function in the electronic device
Equipment, including but not limited to：Common hard disc, hybrid hard disk, solid state hard disc etc..And the disk is using various forms
File system, including but not limited to：FAT, FAT32, NTFS etc..
As shown in figure 1, after step slol, step S103 is performed, wherein, by described in pre-read thread reading
Pre-reading data is cached in the internal memory of electronic equipment, is read during for os starting.
Alternatively, the internal memory can use semiconductor memory cell, including but not limited to：Random access memory（RAM）、
Read-only storage（ROM）, cache memory（Cache）Etc..In general, internal memory has read-write speed more faster than disk
Degree.In the running of electronic equipment, program and data can be typically called in in internal memory from disk operated and from
Reason.
After step s 103, step S105 can be performed, wherein, during os starting, using described pre-
When reading thread to continue to read the pre-reading data, and receiving operating system the request of data is read from disk,
The reading of the pause pre-read thread in the pre-defined time period.
In step S105, start to start in operating system（Typically to be carried out again after system drive file is read）It
Afterwards, continue with the pre-read thread and read the pre-reading data, i.e. read institute from internal memory after os starting
While stating pre-reading data, pre-read thread concomitantly continues to read the pre-reading data.Pre-read thread is at system bottom
Layer operation, it is not necessary to parse data structure, even if in the case where operating system exists and reads obstruction, pre-read thread still may be used
With normal read data.Operating system, can be by request and skew point when file system metadata and file fragmentation data are read
Dissipate and read again and again, speed is very slow, and scheme of the invention, what pre-read thread be able to will read in bottom
Data merge into a data block, from disk disposably（Or with little number of times）By digital independent out.
Embodiments in accordance with the present invention, in above-mentioned steps S101 and S105, pre-read using described in the reading of pre-read thread
Access according to the step of can include：In the case where being spaced less than or equal to pre-defined read access time, using two readings
Request reads two files simultaneously according to disk sort and disk skew；And more than pre-defined read access time interval
In the case of, the time sequencing that file is processed during using two read requests according to os starting successively reads two files.
In prior art approaches, the operating system Windows XP of such as Microsoft, using disk requests queue
Mode reads data, often there are thousands of request queues, now, if the main thread of system sends request, will basis
Its offset row is all in position, often in tail of the queue.Scheme of the invention, the data as far as possible to be read system profit
Read in advance and be cached in internal memory with pre-read thread, and take aforesaid way to avoid queue from blocking.That is, it is being less than or equal to
In the case that pre-defined read access time is spaced, read simultaneously according to disk sort and disk skew using two read requests
Two files, now system interval is very short, without considering time sequencing.And be spaced more than pre-defined read access time
In the case of, the time sequencing that file is processed during using two read requests according to os starting successively reads two texts
Part, this is mainly and the order of file is processed during according to system initialization is read out.
Alternatively, the pre-defined time interval can be chosen according to actual needs, and an example can be 200
Millisecond.In the case where pre-defined time interval is 200 milliseconds, if first millisecond accesses file A, second millisecond of access
File B, then can together read both of these documents；And if first second access file A, second second access file B, then need by
Processed according to time sequencing.In the manner described above, when request is received, it is ensured that only two requests are being queued up.By
Can only singly be processed in request, therefore there are two requests in disk queue and there are thousands of requests for magnetic
The handling capacity of disk IO is the same.
If operating system is in start-up course, outside the discovery pre-read thread cache to the pre-reading data of internal memory
Data in there is no required data, now operating system can read data to disk requests, in above-mentioned steps S105, connect
When receiving operating system the request of data is read from disk, line taking can pre-read described in pause in the pre-defined time period
The reading of journey, for example, suspend 30 milliseconds, this way it is secured that operating system can in time read data, without because of magnetic
Disk queue problem is blocked.Certainly, those skilled in the art can according to actual needs select the above-mentioned pre-defined time
Section, the scope of the present invention is not limited only to 30 milliseconds.
Alternatively, according to one embodiment of present invention, method 100 can also be comprised the following steps：Receiving operation
When system reads the request of data from disk, after the pre-defined time period, do not got from disk in operating system
In the case of the data, the data are read using pre-read thread, and by the data buffer storage to internal memory for operation
System reads.Still by taking 30 milliseconds of pre-defined time period as an example, suspending the reading of the pre-read thread up to 30 milliseconds
Afterwards, if now operating system does not get required data from disk yet, institute can be read using pre-read thread
State data, and by the data buffer storage to internal memory so that operating system reads.
Alternatively, according to one embodiment of present invention, method 100 can also be comprised the following steps：Receiving operation
When system reads the request of data from disk, after the pre-defined time period, still reading ground operating system is detected
In the case that location offsets continuous data, the reading of the pause pre-read thread is kept, read until detecting operating system
The discontinuous data of address offset.During the continuous data of operating system address offset in continuous reading disk, magnetic head is continuously moved
Dynamic, reading efficiency is higher, and now, inconvenience interrupts the reading of operating system, and once detects operating system and read address offset
Discontinuous data, then can stop operation the reading of system, recover reading of the pre-read thread for disk.
Alternatively, according to one embodiment of present invention, method 100 can also be comprised the following steps：Detecting operation
When system carries out self-inspection to disk, suspend the pre-read thread and read the pre-reading data, until detecting disk self-inspection
Terminate.If when operating system carries out self-inspection to disk, the pre-read thread still reads pre-reading data, then may lead
Disk self-inspection exception is caused, therefore now needs to suspend the pre-read thread reading pre-reading data.
Alternatively, according to one embodiment of present invention, method 100 can also be comprised the following steps：Receiving operation
When system reads the request of data from disk, the part in the data that operating system will read from disk are detected includes

After the pre-defined time period, in the case of the data that operating system does not get other parts from disk, using pre-reading
Line taking journey reads the data of the other parts, and by the data buffer storage of the other parts to internal memory so that operating system is read
Take.Specifically, operating system will from disk read data may exist part include pre-reading data in and its
It is partly not included in situation therein, at this point it is possible to the partial data is cached in internal memory so that operating system reads, and
In the pre-defined time period（It is for example as described above 30 milliseconds）Afterwards, other parts are not got from disk in operating system
Data in the case of, it is possible to read the data of the other parts using pre-read thread, and by the other parts
Data buffer storage in internal memory so that operating system reads.Thus, a process for data read request cutting is completed.
Alternatively, in one embodiment of the invention, the above method 100 can also be comprised the following steps：Record operation
The information that system starts, and based on described information and for the pre-defined of one or many os starting before
Pre-reading data, generate for after one or many os starting pre-defined pre-reading data, and according to
The priority that system reads when starting is ranked up to the data in the pre-defined pre-reading data.Wherein, the behaviour
Making the information of system startup includes that the os starting time, the operating system that are spent read pre-reading of being cached from internal memory
The situation of evidence of fetching（For example, the ratio of the pre-reading data hit operating system request of caching）.For example, above-mentioned behaviour can be based on
Make the information and such as pre-reading data of first three sub-operating system startup of system startup to generate the operation system after being used for
The pre-reading data that system starts.Preferably, when pre-reading data is generated, quick reading should be guaranteed, again in operation
Before system request by required digital independent out.
Alternatively, in one embodiment of the invention, methods described 100 can also include step：Detection disk fragmentses
The situation of data movement during arrangement, and situation about being moved according to the data, regenerate the one or many behaviour for after
Make the pre-defined pre-reading data of system startup.Because pre-read thread is pre-read reading with size according to disk skew
Access evidence, therefore after user performs disk fragmentses housekeeping operations, the disk skew of legacy data it may happen that change,
Causing pre-read thread cannot correctly read pre-reading data.Now, using above-mentioned optional step, disk can detected
In the case that data are moved during defragmentation, correct pre-reading data is regenerated according to data movement, for after
Os starting.
