The invention discloses a kind of storage method, be used for solving present in prior art video recording system will
Data exist when being stored in storage device, the longest owing to writing, the inferior problem of video recording caused.
Seeing flow chart 1, storage method disclosed by the invention comprises the following steps:
Step S1, collection include the image of the program of parameter preset, and described parameter preset at least includes:
With described in the number of big relief area set in advance and the size of each big relief area, described storage device
The sevtor address that each big relief area is the most corresponding, the data address that each big relief area described is the most corresponding；
It addition, when video recording system is provided with multiple storage device, described pre-conditioned also include: described greatly
The storage device that relief area is corresponding, in order to select suitable storage device, it is achieved the storage to data；Its
In, can be completed containing pre-conditioned program by the shooting of the photographic head of video camera, computer is first-class
The collection of image.
Step S2, described image is resolved, create the big relief area corresponding with described parameter preset.
During actual application, can be carried out by the image of the described program to collecting of the processor in camera system
Dissection process, to create described big relief area, furthermore it is possible to set in storage by described big setting buffers
Standby interface layer, naturally it is also possible to be arranged on other regions.Meanwhile, when arrange big relief area be multiple
Time, the plurality of big relief area can be arranged on different regions, but generally, selection is by described
Multiple big setting buffers are in same region, such as the interface layer of described storage device, in order to can be in time
Storage allocation and releasing memory, reduce the waste of internal memory.Wherein, described can containing pre-conditioned program
With as follows:
When arranging relief area, it is contemplated that the problem of memory fragmentation, if application and releasing memory frequently,
By increasing the burden of video recording system, being therefore also provided with minibuffer district, described big relief area can store one
Or the data of multiple sector, and the amount of capacity in each minibuffer district is a sector-size, say, that
Each big relief area comprises one or more minibuffer district.
It addition, in terms of arranging big relief area, multiple big relief area can be arranged by a program simultaneously,
Such as, the size pre-setting described big relief area is 64K, then, when arranging all big relief areas
If the parameter of capacity sum is 128K, then be provided with two big relief areas the most simultaneously.
By program above it will be seen that each big relief area comprises N number of minibuffer district, the number of N
Value size is by program: " BIG_ASAY_BUF_SIZE/ sector-size " determines, generally by described big slow
Rush district and be set to 8K byte, or be set to the capacity of other sizes.
Step S3, with reference to sevtor address respectively the most corresponding with each big relief area described in described storage device,
Described big relief area is ranked up；By program above, data to be stored should be stored in
Which sector of storage equipment is fixing, and when creating big relief area, has preset described big slow
Rushing the sevtor address of described storage device corresponding to district, described big relief area sets according to corresponding described storage
The address sort of standby sector, and the minibuffer district in described big relief area is also carried out according to sevtor address
Sequence, for example, it is possible to from small to large described big relief area is ranked up according to sevtor address, the most every
Minibuffer district in individual big relief area also arranges according to the sevtor address of the described storage device of its correspondence
Sequence, thus, the minibuffer district in described each big relief area, and described multiple big relief area, energy
Enough form a tactic chained list, by the head of big relief area as gauge outfit.See Fig. 2, be
The chained list schematic diagram of the relief area created.
Step S4, when needs storage data time, by data to be stored write relative with described data to be stored
In the described big relief area answered；When needs storage data, system can produce write order, and write described
Order is sent to described big relief area, and then performs described data to be stored are write described big relief area
Operation.
Step S5, write after data in described big relief area, create extra buffer, and by described one
Data write extra buffer in individual or multiple big relief area；In writing data into described big relief area
After, create an extra buffer, the capacity of described extra buffer however less than described big relief area,
When as described in the size of big relief area be 8K byte time, described extra buffer can be 64K byte,
Or it is the capacity of other sizes, after described data to be stored write extra buffer, then faces described
Time relief area in data write storage device time, can be the most with the data of write once, and, by
In described big relief area, described minibuffer district be all tactic, it is not necessary to the process of lookup, thus
That avoid that prior art occurs because skip write, along writing the longest time-consuming problem caused.
It addition, be by a big relief area or by the data write extra buffer in multiple big relief areas,
Depend on the amount of capacity of described extra buffer, if the size of described extra buffer and described big slow
The size rushing district is identical, can the most only write the data of a big relief area, if described interim buffering
If the size in district is the size of multiple big relief area, can the data of multiple big relief areas be write every time
In extra buffer.
Step S6, by the sector of the data write storage device write in described extra buffer.Writing
When entering storage device, if described video recording system is provided with multiple storage device, can be according to above
Program language, select corresponding storage device, by described extra buffer data write described in deposit
In storage equipment.
By the method for step S1 to step S6, when writing data into storage device, be first by described
In data write relief area, and the data in one or more relief areas are write in extra buffer, by
Bigger in the capacity of described extra buffer, it is possible to store more data simultaneously, thus by described temporarily
During data write storage device in relief area, can be the most with the data of write once, and, described
Big relief area, described minibuffer district are all tactic, after writing described extra buffer, described
Data to be stored are also to arrange in order, storage device of writing direct, it is no longer necessary to search internal memory
Fragment, it is to avoid because skip write, along writing the time delay caused, improve video recording quality.
It addition, shown in schematic flow sheet as disclosed in fig. 3, by described to be stored data writes institute
When stating big relief area, comprise the following steps:
The described big relief area that step S21, judgement have created is to be write with described data to be stored
The sector of storage device is corresponding.Due to described data to be stored want write storage device which sector it
In be fixing, and according to program provided above, described big relief area is when creating,
Specify that the corresponding relation of sevtor address with described storage device.Accordingly, it would be desirable to judge the institute created
The sector stating the big relief area storage device to be write with described data to be stored is corresponding, if
It is then to perform step S25, if it is not, then perform step S22.
Step S22, judge whether the region at place, described big relief area has enough memory spaces, such as,
When the interface layer that the region at place, described big relief area is described storage device, described interface layer to be judged
Whether also have enough memory spaces, if it is not, perform step S23, if it has, then perform step
S24；
Step S23, in step S22, when the region judging place, described big relief area does not has enough
During memory space, explanation system does not have internal memory can distribute, therefore, big by original written data
In data write storage device in relief area, to obtain new internal memory, and enter step S24.
Step S24, corresponding the delaying greatly in sector of the storage device that establishment is to be write with described data to be stored
Rush district, and described data to be stored are write in described newly created big relief area, and deposit according to described waiting
The sevtor address of the storage device that storage data are corresponding, is ranked up described big relief area.Such as, original
The sevtor address coming last minibuffer district of first big relief area is 0XFFFFFF00, original second
The sevtor address in first minibuffer district of individual big relief area is 0XFFFFFFFF, newly created big buffering
Sevtor address in district is between 0XFFFFFF00 and 0XFFFFFFFF, then by newly created big buffering
District inserts between the former first big relief area and former second largest relief area, and is set to second largest relief area,
Postponing in former second largest relief area and big relief area afterwards, i.e. revises the information of original chained list.
Step S25, described data to be stored are write in described big relief area.When specifically performing,
When described data to be stored are write in described big relief area, if there have been data described big relief area
Time, described data to be stored can be re-write, to cover original data.

When creating a big relief area, owing to not writing data, so the relief area linked list head used points to sky,
When needs storage data, if the described big relief area created, to write with described data to be stored
The sector of storage device there is corresponding relation, then described data to be stored are write in this big relief area
If originally there are data in described big relief area, then it is assumed that existing data are old data,
By described data cover to be stored at this big relief area, if originally there are not data, treat described
In the corresponding minibuffer district of storage data write, and this minibuffer district is added to use buffering
On the chained list in district, and ensure the sortord of the relief area used.If when writing data, the most enough
The relief area of size, and when system is not reaching to the threshold values of internal memory, then application is next big the most again
Relief area, and when system has reached the threshold value of internal memory, the data in each big relief area can be write
Storage device, and re-create new relief area.
By described step S21 to workflow disclosed in step S25, data to be stored can be write
In described big relief area, and in the sector of described data to be stored described storage device to be write with
When the big relief area created does not exists corresponding relation, new big relief area can be created, and new creating
Behind big relief area, still it is ranked up according to the sevtor address of corresponding described storage device.It addition, this
Bright disclosed scheme, increases the technology of relief area in a storage arrangement, can allow a thread that data are write
Enter relief area, the most directly return, it is not necessary to wait, be returned to after data are write, thus do not have
Every time write time-consuming the biggest is set because storing, causes certain operations to be normally carried out.And write relief area
Data will carry out writing when backstage during storage arranges by another independent thread.
It addition, shown in schematic flow sheet 5 as disclosed in figure, the data of said write relief area are being write
When entering extra buffer, comprise the following steps:
Step S31, judge whether described big relief area has data to be stored.When in described big relief area
When having data to be stored, write order can be produced, to perform the operation of step S32；If through judging,
When there is no data to be stored, block the thread writing data into extra buffer, until judging described
There are data to be stored in big relief area.
Step S32, establishment extra buffer, the capacity of described extra buffer is greater than described big relief area
Capacity, meanwhile, described extra buffer can be arranged on interface layer, it is also possible to is arranged on other positions,
The application does not limits.But in order to reduce the time of described data to be stored write extra buffer,
Currently preferred mode is that described extra buffer is arranged on the region of described big setting buffers, with
Reach to distribute in time, the purpose of releasing memory.
Step S33, by the data to be stored in described big relief area, according to the sequential write of described big relief area
Enter in described extra buffer, and return execution step S31, i.e. the data in described big relief area being write
After entering described extra buffer, more whether there are data to be stored in judging described big relief area.Concrete real
Shi Shi, inquire about the address in the relief area of last use whether with the big relief area of this secondary use
Address is continuous, if continuous print, the described big setting buffers that will use is used, from
And update link table information, and if discontinuous, then by little slow for first in described big buffering to be used
Rush the linked list head address that the address in district is set to use
