Description
Technical field
The present invention relates to a kind of methods of improve data transfer performance in technical field of memory more particularly to solid state hard disk.
Background technique
In SSD, be related to a large amount of data moves operation, such as data are moved to SSD when write operation, reads behaviour
Data are moved out from SSD when making.In order to improve the efficiency of SSD data-moving, generally can all DMA, DMA be used to be responsible for data
Work is moved from source address to destination address, to mitigate the intervention of SSD innernal CPU.DMA use to a certain extent,
The intervention for reducing CPU improves system performance, but a large amount of data-moving works, and also has a great impact to performance.
Based on the above issues, therefore, to those skilled in the art, how to simplify data from source address to destination
Move the technical issues of process is urgent need to resolve in location.
Summary of the invention
Technical problems based on background technology, the invention proposes improve data transfer performances in a kind of solid state hard disk
Method, simplify data from source address to destination address and move process, only by maintenance system buffer list, data
Source buffer list and data purpose buffer list, greatly reduce the time of data-moving, improve the effect of data transmission
SSD data transmission performance can be greatly improved in rate, improve product competitiveness.
The method of improve data transfer performance in a kind of solid state hard disk proposed by the present invention, comprising the following steps:
Buffer area in system is divided into multiple buffering area block；
System buffer list is created, and the caching block is added in above system buffer list；
Construct data source buffer list, and the distributing buffer block from the system buffer list；
Create data purpose buffer list；
When data reach buffer blocks in data source buffer list, the buffer area in data source buffer list is recorded
Block has valid data, and data purpose buffer list is added in the buffer blocks, and the buffer blocks are delayed from data source
It rushes in area's list and deletes.
Preferably, the multiple buffering area block size that Division is buffered in system is equal.
Preferably, further comprising the steps of: when data purpose buffer area is added in buffer blocks in data source buffer list
When list, equivalent amount buffer blocks are distributed from the list of system buffer, data source buffer list is added.
Preferably, further comprising the steps of: when the data volume of buffer blocks in data purpose buffer list reaches default
When value, the data of buffer blocks in data purpose buffer list are written in NAND, and empty data purpose buffer list
The data of middle buffer blocks, and the buffer blocks after emptying are added in the list of system buffer.
Preferably, further comprising the steps of: the buffer blocks after emptying are deleted from data purpose buffer list.
The method of improve data transfer performance, passes through maintenance system buffer area in a kind of solid state hard disk provided in the present invention
List, data source buffer list and data purpose buffer list, that reduces data moves operation, is arranged by system buffer
Table dynamically distributes data source buffer area, corresponding slow by modification data source buffer list and data purpose buffer list mark
Rush the effect of block；Changed data and moved process from source address to destination address, only by maintenance system buffer list,
Data source buffer list and data purpose buffer list, greatly reduce the time of data-moving, improve data transmission
Efficiency, can be greatly improved SSD data transmission performance, improve product competitiveness.
Detailed description of the invention
Fig. 1 is the flow chart of the method for improve data transfer performance in a kind of solid state hard disk proposed by the present invention.
Specific embodiment
As shown in FIG. 1, FIG. 1 is the processes of the method for improve data transfer performance in a kind of solid state hard disk proposed by the present invention
Figure.
The present invention is described in detail below with reference to the accompanying drawings and embodiments.
A kind of method of improve data transfer performance in solid state hard disk, comprising the following steps:
S1: buffer area in system is divided into the buffer blocks that multiple sizes are 4K；
S2: creation system buffer list, and the caching block is added in above system buffer list；
S3: building data source buffer list, and the distributing buffer block from the system buffer list；
S4: creation data purpose buffer list；
S5: when data reach buffer blocks in data source buffer list, it is slow to record this in data source buffer list
It rushes block and has a valid data, and the buffer blocks are added data purpose buffer list, and by the buffer blocks from data
It is deleted in the buffer list of source；
S6: equivalent amount buffer blocks are distributed from the list of system buffer, data source buffer list is added；
S7: when the data volume of buffer blocks in data purpose buffer list reaches preset value, data purpose is buffered
In area's list in the data write-in NAND of buffer blocks, and the data of buffer blocks in data purpose buffer list are emptied, and
Buffer blocks after emptying are added in the list of system buffer, and by the buffer blocks after emptying, from data purpose buffer area
It is deleted in list.
The foregoing is only a preferred embodiment of the present invention, but scope of protection of the present invention is not limited thereto,
Anyone skilled in the art in the technical scope disclosed by the present invention, according to the technique and scheme of the present invention and its
Inventive concept is subject to equivalent substitution or change, should be covered by the protection scope of the present invention.
