With reference to Figure of description, the embodiment of the present invention is described in further detail；
As shown in Fig. 2 the data transmission method flow chart provided for the embodiment of the present invention one, including： S201 :Host receiving data modification instruction, the data modification instruction includes address information and data message；
Before this step, main frame is after the data read command of user's triggering is received, data read request is sent to storage device, the data read request includes the address information of the page of main frame needs reading, the address information can be logical address, virtual address or physical address of the page etc., the data read request that storage device Receiving Host is sent, and the page pointed by the address information in the data read request is sent to main frame；Main frame is after the page of storage device transmission is received, during the page write-in Slow of reception is deposited.
In step S201, main frame is read after the above-mentioned page, if receiving the data modification instruction of user's triggering,
Then determine the address information and data message in the data modification instruction.Wherein, the data message includes amended data；The address information is used to indicate the position in the page residing for the data of modification, can specifically include page bias internal amount.Such as, the data modification instruction indicates to add the amended data included in the data message at the position that page bias internal amount is 111000100000 in the above-mentioned page of reading.
S202:The main frame is according to the data message, and at least one data cell that the page of middle storage is deposited to the Slow pointed by the address information is modified；
In this step, main frame Slow is deposited in each page according to setting granularity division as some, each part is referred to as a data cell, set the size of granularity namely the size of each data cell, in specific implementation, the size of data cell can be according to actual needs set, such as, each page according to afterbody high speed Slow can be deposited row（Last Level Cache Line) granularity divided, and so, the size of each data cell is the size of Last Level Cache Line granularities, is tens bytes.
In above-mentioned steps, main frame is after the data modification instruction of user's triggering is received, address information in being instructed according to the data modification, it is determined that needing the data cell belonging to the data of modification, and the data message in being instructed according to data modification, pair determine data cell in data modify.Such as, the page division for being 4KB by the size of reading is five data cells, and the corresponding ranges of logical addresses of each data cell is followed successively by： 000000000000-1100110011 , 1100110011-11001100110 , 11001100110-100110011001 , 100110011001-110011001100 ,
110011001100-111111111111 ;If the data modification instruction indicates to add the amended data included in the data message at the position that page bias internal amount is 111000100000 in the page of reading, then according to page bias internal amount 111000100000 (belonging to above-mentioned ranges of logical addresses 110011001100-111111111111), it is determined that needing last data cell that the data cell changed is the page.
S203 :The main frame generates data write request；Wherein, the data write request includes the address identification message of amended each data cell and amended each data cell；The address identification message is used for the address that the storage device determines amended each data cell.
, can be to be amended per number when being modified to data cell in specific implementation process
Set and mark according to unit；According to the mark of setting, the address identification message of amended each data cell and amended each data cell is determined.Setting the mode of mark has a variety of, such as, can use dirty bit identification method or data unit number label method.According to dirty bit identification method, then the address and the dirty position of the amended affiliated page of each data cell of the main original position including amended each affiliated page of data cell of address above mentioned identification information.According to data unit number label method, then address above mentioned the identification information mainly address of the original position including amended each affiliated page of data cell and the element number of amended each data cell.
S204:The data write request is sent to the storage device by the main frame so that the storage device writes amended each data cell in the memory of the storage device according to the address of amended each data cell.
In above-mentioned steps S203 and step S204, address identification message of the main frame according to amended each data cell and for identifying amended each data cell, generate data write request, and it is sent to storage device, address identification message of the storage device in the data write request, determine the address of amended each data cell, such as virtual address, logical address, physical address, according to the address of determination, the corresponding position that amended each data cell is write in memory.
In above-mentioned steps S202, main frame to any one data cell after modifying, set and mark for the data cell, changed with identifying the data cell, finally, main frame determines that these mark the address identification message of the amended data cell identified respectively and amended data cell according to one or more marks of setting.Specifically, mark is set there are following two modes：
The first：Dirty position（Dirty bit) label method；Here, dirty position is data cell dirty bit, for representing whether corresponding data cell is modified；
Specifically, the main frame sets mark for amended each data cell, including：The corresponding dirty position of amended each data cell is carried out set by the main frame；The main frame generates the data write request according to the mark, including：The main frame is according to the dirty position of each set, determine the address identification message of amended each data cell and amended each data cell, wherein, the address identification message includes the address and the dirty position of the amended affiliated page of each data cell of the original position of amended each affiliated page of data cell.
In aforesaid way, if some data cell in the page is changed, the corresponding dirty position of the data cell is subjected to set, for example, it is 1 by the dirty position, the dirty position for not having set in the page then represents that the corresponding data cell in the dirty position is not changed；Here, if the size of full page is 4KB, each data cell is 64 bits（Byte 8byte (i.e. 64bit)), is then needed to identify the dirty position of all data cells in the page；It is the schematic diagram for marking amended each data cell in the embodiment of the present invention using dirty bit identification method as shown in Fig. 3.
In specific implementation process, the data cell after all modifications in the page can be determined after it is determined that completing modification to full page, according to the dirty position Jing Guo set, and by the address of the original position of the page, the dirty position of the page（Dirty position including set and the dirty position without set）, and each set the corresponding data cell in dirty position generate a packet after be sent to storage device, be the schematic diagram of amended each data cell that main frame is sent to storage device and the address identification message based on dirty position as shown in Fig. 4.
Storage device is after above-mentioned amended data cell and address identification message based on dirty position is received, according to the address identification message, it is determined that the address of each amended data cell, each amended data cell is write in corresponding address；In specific implementation, for any one amended data cell, storage device determines the serial number and the product of data unit size of the dirty position corresponding to any one described amended data cell；It is determined that the address of any one amended data cell is the product and the address of the original position of any one amended affiliated page of data cell and value.Specifically, for any one amended data cell, storage device can according to below equation determine described in any one amended data cell address A:
A = B + n X k
Wherein, B is the address of the original position of any one amended affiliated page of data cell, the dirty position that n represents corresponding to any one described amended data cell is n-th of dirty position of any one amended affiliated page of data cell, and k is the size of data cell.
In above-mentioned formula, n-th of dirty position refers to full page being in turn divided into after multiple data cells according to the logical order of data, the dirty position of correspondence nth data element.
