It should be appreciated that the general description of the above and detailed description hereinafter are only exemplary and explanatory, not
The disclosure can be limited.
Brief description of the drawings
Accompanying drawing herein is merged in specification and constitutes the part of this specification, shows the implementation for meeting the disclosure
Example, and be used to together with specification to explain the principle of the disclosure.
Fig. 1 is a kind of flow chart of method for writing data according to an exemplary embodiment.
Fig. 2 is a kind of block diagram of data transfer apparatus according to an exemplary embodiment.
Fig. 3 is a kind of another block diagram of data transfer apparatus according to an exemplary embodiment.

Embodiment
Here exemplary embodiment will be illustrated in detail, its example is illustrated in the accompanying drawings.Following description is related to
During accompanying drawing, unless otherwise indicated, the same numbers in different accompanying drawings represent same or analogous key element.Following exemplary embodiment
Described in embodiment do not represent all embodiments consistent with the disclosure.On the contrary, they be only with it is such as appended
The example of the consistent apparatus and method of some aspects be described in detail in claims, the disclosure.
Electronic equipment in the embodiment of the present disclosure for example can be the PC (Personal based on android system
Computer, personal computer), PAD (Personal Digital Assistant, tablet personal computer), mobile phone etc. it is different
Electronic equipment, the embodiment of the present disclosure is not construed as limiting to this.
Fig. 1 is a kind of flow chart of method for writing data according to an exemplary embodiment, as shown in figure 1, the number
It is used for according to wiring method in electronic equipment, comprises the following steps.
In step s 11, whether the size of the data to be stored in detection internal memory reaches preset data amount, wherein, preset
Data volume is more than the size of single memory page in memory module.
In step s 12, when the size of data to be stored reaches preset data amount, the use developed based on User space is called
Family space file system FUSE write operation.
In step s 13, according to write operation, data to be stored are write in memory module.
Memory module such as can be the memory built in SDcard etc. in the electronic device, can be used for storage file and
Data.
Preset data amount can be the amount of the data of the write operation set in advance that can trigger User space.For present count
It is how many actually according to the value of amount, the embodiment of the present disclosure is not construed as limiting, as long as the size more than single memory page in memory module is
Can.For example, single memory page in memory module, that is, page size is 4KB, then preset data amount can be set
For 8KB, 16KB, 64KB, etc..
For example, preset data amount can be set as 128KB, then during write-in data, number to be stored in internal memory can be detected
According to size whether reached 128KB, when the data to be stored stored in internal memory have reached 128KB, just trigger kernel module
What (i.e. data can be write memory module by Kernel Fuse modules based on write request from internal memory) carried out User space writes behaviour
Make, and then 128KB data are write in memory module (such as SDcard).It can be seen that, compared to the data of memory page size
Amount triggering write operation, is that foundation can effectively reduce write operation to trigger the write operation of User space according to the preset data amount of setting
The number of times of triggering, and then the efficiency of data write-in is improved, while also mitigating the processing load of kernel module.
Optionally, carry option setting preset data amount can be passed through during carry.
Application program must first pass through kernel module, kernel mould to the file write-in based on the Fuse file system developed every time
Block has permission when decision writes data into User space file system, therefore the mistake of carry can be being carried out to memory module
Cheng Zhong, preset data amount is set by carry option.
Such as, to set preset data amount is 128KB, there is a max_ in struct fuse_init_out structures
Write variables, then 128KB directly can be assigned to max_write variables.So, can be with more convenient to present count
It is configured according to amount.
Optionally, preset data amount can be the integral multiple of the size of single memory page.
For example, the size of single memory page (page) be 4KB, then can set preset data amount for 8KB, 16KB,
64KB, 128KB, etc..So, data to be stored preferably can be write into memory module.
Optionally, when the size of data to be stored is not up to preset data amount, preservation operation can also be obtained, then can
, then will be to be stored according to operation is preserved, to call the user's space file system FUSE developed based on User space write operation
In data write-in memory module.
In other words, the corresponding data to be written of write request are possible to be not reaching to preset data amount, then if with
The operation that family is preserved, can still trigger the write operation of User space, be written into data write-in memory module.
For example, the corresponding data to be written of the write request of user are 64KB, preset data amount is 128KB, if user enters
Preservation of having gone is operated, and can be triggered the write operation that kernel module carries out User space, will be not reaching to the 64KB's of preset data amount
In data write-in memory module to be stored.By such mode, even if the data of user's write-in are not reaching to preset data amount,
Also data can be write by preserving operation, the data-handling capacity of electronic equipment is stronger.
