Detailed Description
Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numbers in different drawings refer to the same or similar elements, unless otherwise indicated. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
In the related art, HPB (collectively Host performance boost, chinese name, host performance enhancer) is used to improve read-write performance. However, HPB requires storing L2P tables in memory cells (e.g., DDR, DRAM), which may occupy memory of the memory cells, and the mapping range of HPB is limited.
In the actual use process, since the HPB needs to map more storage areas of the UFS unit, the L2P table stored in the memory unit needs to cover as much storage areas of the UFS unit as possible, which causes the L2P table to occupy more memory of the memory unit. In addition, because the mapping range of the HPB is limited, the HPB cannot map all storage areas of the UFS unit, and it is difficult to ensure that the area where the data is read and written each time belongs to the mapping area of the HPB, so that the hit ratio of the read and write is poor, the read and write performance is still poor, and the phenomenon is more obvious during random read and write.
The present disclosure provides a storage method, applied to a terminal, where a flash memory unit of the terminal includes a first storage partition and a second storage partition, where the first storage partition is a mapping area of a host performance enhancer (HPB), in this method, when a remaining capacity of the first storage partition is greater than or equal to a set capacity and a data type to which data to be stored belongs is a set type, the data to be stored is stored to the first storage partition, that is, the HPB is only used to store the set type of data to the first storage partition, the first storage partition is only used to store a set type of file, and the HBP is only used to perform a read-write operation with respect to the first storage partition, so that a read-write hit rate of the HPB on the set type of data can be improved, and a read-write performance on the set type of data can be improved.
In one exemplary embodiment, a storage method is provided for a terminal, a flash memory unit of the terminal including a first storage partition and a second storage partition, the first storage partition being a mapped region of a host performance enhancer (HPB). The flash memory unit may include a Universal Flash Storage (UFS) unit, a Solid State Disk (SSD), and the like, which are not limited herein. In general, when the terminal is a mobile phone, the flash memory unit is a UFS unit. When the terminal is a computer, the flash memory unit is SSD.
Referring to fig. 1, the method includes:
s110, acquiring data to be stored;
and S120, if the residual capacity of the first storage partition is larger than or equal to the set capacity and the data type of the data to be stored is the set type, storing the data to be stored into the first storage partition.
In step S110, the data to be stored refers to data to be stored, and the data to be stored may be a file to be stored. The data to be stored may be data generated by an application program, or may be other data, which is not limited herein.
For example, in the process of using the application program by the user, the application program can generate corresponding use data, the use data can be transmitted to the processor of the terminal, the processor can acquire the use data, and the use data can be recorded as data to be stored. The usage data may be files downloaded by the user through the application.
In step S120, the following two determinations need to be made:
judging 1, judging whether the residual capacity of the first storage partition is larger than or equal to the set capacity;
and 2, judging whether the data type of the data to be stored is a set type or not.
The above-described determination 1 and determination 2 may be performed simultaneously, or may be performed sequentially or in reverse order, and are not limited thereto.
In the judgment 1, the set capacity can be set before the terminal leaves the factory or after the terminal leaves the factory, and after the set capacity is set, the set capacity can be modified to better meet the requirements of users. The specific value of the set capacity is determined according to the actual situation and is not limited herein.
In example 1, the total capacity of the first storage partition is a, and the set capacity may be 10% of the total capacity of the first storage partition, that is, 10% a.
In the determination 2, the data to be stored may be a file to be stored, and the data type to which the data to be stored belongs, that is, the data type to which the file to be stored belongs. Wherein the data type to which the data to be stored belongs can be determined according to the data amount of the data. For example, the data to be stored whose data amount is smaller than or equal to the set value may be determined as the set type of data. That is, if it is determined that the data amount of the data to be stored is less than or equal to the set value, it is determined that the data type to which the data to be stored belongs is the set type.
The set value can be set before the terminal leaves the factory or after the terminal leaves the factory, and can be modified after the set value is set so as to better meet the requirements of users. The specific value of the set value is determined according to the actual situation, and is not limited herein. For example, the setting value may be determined according to the size of one read-ahead of the page cache. The page cache is also called as pcache, wherein the text name is page cache memory, and is called page cache for short. The size of one read-ahead of the page cache is one page, typically 4K. When the linux reads and writes the file, the linux is used for caching the logic content of the file, so that the access to images and data on a disk is quickened.
In example 2, the setting value may be set to the size of four pre-reads of the page cache, that is, the setting value may be set to 4*4 =16k. If the data quantity of the data to be stored is less than or equal to 16K, the data type of the data to be stored is considered to be a set type, namely the type of the data to be stored is considered to be a small file type, and the data to be stored is considered to be a small file. Other types of data to be stored may be considered large files.
When the set type is the small file type, the first storage partition is only used for storing the small file, the total capacity of the first storage partition can be smaller than that of the second storage partition, so that the flash memory unit can be ensured to be provided with enough first storage partitions to store the small file, the memory of an excessive memory unit can be prevented from being occupied by an HPB function, the first storage partition can be ensured to be completely covered by the HPB function, the hit rate of the small file is improved, and the read-write performance of the small file is improved.
It should be noted that the second storage partition may not only store data other than the set type, but may also be used to store data of the set type when the first storage partition is no longer able to store data of the set type.
Example 3 in the case of the use of the heat treatment agent,
the total capacity of the partition storing user data (userdata) in the UFS unit is b, and the partition storing user data can be divided into a first storage partition and a second storage partition. Wherein the first memory partition may be denoted as userdata sf, and its total capacity may be 10% b; the second memory partition may be denoted userdata bf, which may have a total capacity of 90% b. In this example, the first storage partition is used only to store data of the set type and the second storage partition is used to store data of all types (including the set type and other types).
In this example, the set capacity may be 10% of the overall capacity of the first storage partition, i.e., the set capacity is 1%b. The set value is 16K.
In this example, if it is determined that the remaining capacity of the first storage partition is greater than or equal to 1%b and it is determined that the data amount of the data to be stored is less than or equal to 16K, the data to be stored may be stored to the first storage partition by the HPB function, that is, by the L2P table in the memory unit.
The processor (CPU) of the terminal may obtain, according to the L2P table, a Physical address corresponding to the logical address of the data to be stored, where the processor sends an instruction including the Physical address to the UFS unit, and the UFS unit may access, based on the received instruction, the data corresponding to the Physical address (i.e., the data to be stored) to store the data to be stored to the Physical address in the first storage partition.
In this example, if any of the following is determined, the L2P table may be loaded in the UFS unit, and the data to be stored is stored in the second storage partition through the L2P table loaded by the UFS unit:
case 1, determining that the remaining capacity of the first storage partition is less than 1%b, and determining that the data amount of the data to be stored is less than or equal to 16K;
case 2, determining that the remaining capacity of the first storage partition is greater than or equal to 1%b, and determining that the data amount of the data to be stored is greater than 16K;
in case 3, it is determined that the remaining capacity of the first memory partition is smaller than 1%b, and it is determined that the data amount of the data to be stored is larger than 16K. ,
it should be noted that, besides the type to which the data to be stored belongs, the type to which the data to be stored belongs may be distinguished by other means, and the set type may be a small file type or another type, which is not limited herein. For example, the setting type may be a text type, thereby improving the read-write performance of data of the text type.
The method can improve the read-write hit rate of the data of the set type and improve the read-write performance of the data of the set type, and in addition, as the mapping area of the HPB is the first storage partition, the memory occupation of the L2P table corresponding to the HPB can be reduced, so that the memory of the memory unit is released.
In addition, as the system generates certain fragments aiming at the reading and writing of the data, the UFS unit needs to be subjected to the defragmentation, the prior strategy is to carry out the full disk defragmentation of the UFS unit at a proper time, and the management logics of different types of data are different. For example, unlike the management logic of small files and large files, the reading and writing of small files are more frequent, and the defragmentation frequency of small files is higher than that of large files, so that the first storage partition is only used for storing small files, and the defragmentation efficiency can be improved.
In one exemplary embodiment, a storage method is provided for a terminal, a flash memory unit of the terminal including a first storage partition and a second storage partition, the first storage partition being a mapped region of a host performance enhancer (HPB).
Referring to fig. 2, the method may include:
s210, judging whether the residual capacity of the first storage partition is larger than or equal to the set capacity; if the remaining capacity of the first storage partition is greater than or equal to the set capacity, executing step S220; if the remaining capacity of the first storage partition is smaller than the set capacity, step S240 is performed.
S220, judging whether the data type of the data to be stored is a set type or not; if the data type to which the data to be stored belongs is the set type, executing step S240; if the data type to which the data to be stored belongs is not the set type, step S240 is performed.
S230, storing the data to be stored into the first storage partition.
S240, storing the data to be stored in the second storage partition.
In the method, the residual capacity of the first storage partition is firstly judged, and if the residual capacity of the first storage partition is smaller than the set capacity, the data to be stored can be directly stored in the second storage partition. If the residual capacity of the first storage partition is greater than or equal to the set capacity, determining whether the data type of the data to be stored is the set type. And if the data type of the data to be stored is not the set type, storing the data to be stored into the second storage partition. And if the data type of the data to be stored is the set type, storing the data to be stored into the first storage partition.
Example 1 in the case of the use of the heat-sensitive material,
the total capacity of the partition storing user data (userdata) in the UFS unit is b, and the partition storing user data can be divided into a first storage partition and a second storage partition. Wherein the first memory partition may be denoted as userdata sf, and its total capacity may be 10% b; the second memory partition may be denoted userdata bf, which may have a total capacity of 90% b. The set capacity may be 10% of the total capacity of the first storage partition, i.e., the set capacity is 1%b. The data to be stored is a file to be stored. The setting type is a doclet type.
In this example, it is first determined whether the remaining capacity of the first storage partition is sufficient. If the remaining capacity of the first storage partition is determined to be less than 1%b, it is indicated that the remaining capacity of the first storage partition is insufficient, and the L2P table may be loaded in the UFS unit, and the file to be stored may be stored in the second storage partition through the L2P table loaded by the UFS unit.
If the residual capacity of the first storage partition is determined to be greater than or equal to 1%b, further judging whether the file to be stored belongs to a small file type.
If the data type of the file to be stored is determined not to be the small file type (i.e. the file to be stored is a small file), the L2P table can be loaded in the UFS unit, and the file to be stored is stored in the second storage partition through the L2P table loaded by the UFS unit.
If the data type of the file to be stored is determined to be a small file type (i.e., the file to be stored is a small file), the file to be stored can be stored to the first storage partition through the HPB function, that is, the file to be stored is stored to the first storage partition through the L2P table in the memory unit.
In this example, when an application program needs to read or modify an already stored file, the corresponding partition may be taken as an operation target according to original information stored in the file. When the small file is operated, the operation of the system is random reading and writing, at this time, the L2P table of the file is stored in a memory unit (such as DRAM) of the mobile phone due to the existence of the HPB function, and the UFS unit does not need to reload the L2P table, so that the reading and writing performance of the small file can be improved. When the operation of the large file is carried out, the operation of the system is sequential reading and writing, and the storage mode and the operation type of the system are completely consistent with those of the traditional method, so that the system does not have negative influence.
In the method, when the residual capacity of the first storage partition is insufficient, the type of the data to be stored is not required to be judged, the data to be stored can be directly stored into the second storage partition, and the data storage efficiency is further improved.
In one exemplary embodiment, a storage method is provided for a terminal, a flash memory unit (e.g., UFS unit) of the terminal including a first storage partition and a second storage partition, the first storage partition being a mapped region of a host performance enhancer (HPB).
The method may include:
and S310, under a set scene, if the residual capacity of the first storage partition is determined to be greater than or equal to the set capacity and the data type of the stored data in the second storage partition is determined to be the set type, the stored data is transferred to the first storage partition.
The setting scene can be set before the terminal leaves the factory or after the terminal leaves the factory, and in addition, after the setting of the setting scene is finished, the setting scene is modified so as to better meet the requirements of users. The setting scene can be determined according to practical situations, and is not limited herein.
The setting scenario may be that the terminal is in an idle charging scenario, that is, the user does not use the terminal, and the terminal is in a charging state. The setting scenario may also be that the terminal is in a night standby scenario, i.e. the user is not using the terminal for a setting period of time, which may be 20:00 a day to 6:00 a day. Of course, the setting scene may be other scenes according to the actual requirement, and is not limited herein.
In this step, in the setting scenario, the following two determinations are required:
judging 1, judging whether the residual capacity of the first storage partition is larger than or equal to the set capacity;
and judging 2, judging whether the data type of the stored data in the second storage partition is a set type or not.
The above-described determination 1 and determination 2 may be performed simultaneously, or may be performed sequentially or in reverse order, and are not limited thereto.
In decision 2, the stored data refers to the stored data in the second storage partition, which may be a stored file.
The data stored in the second storage partition can be scanned, and whether the data type of the scanned stored data belongs to a set type or not can be judged one by one. The specific method for determining whether the data type of the stored data is a set type may refer to determining whether the data type of the data to be stored is a set type, which is not described herein.
In the method, under a set scene, if the residual capacity of the first storage partition is determined to be greater than or equal to the set capacity and the data type of the stored data in the scanned second storage partition is determined to be the set type, the stored data can be transferred to the first storage partition, and a new storage address of an application corresponding to the stored data can be notified, so that the application can read the stored data from the first storage partition directly based on an HPB function, and the read-write performance of the stored data is improved.
In this method, after each time the stored data is transferred to the first storage partition, it is required to re-determine whether the remaining capacity of the first storage partition is greater than or equal to the set capacity, so as to better ensure that the first storage partition has enough remaining capacity to store the new set type of data.
According to the method, the stored data of the set type in the second storage partition can be transferred to the first storage partition in time, so that the read-write performance of the data of the set type is better improved, and the use experience of a user is further improved.
In one exemplary embodiment, a storage method is provided for a terminal, a flash memory unit (e.g., UFS unit) of the terminal including a first storage partition and a second storage partition, the first storage partition being a mapped region of a host performance enhancer (HPB).
The method may include:
s410, according to the fragmentation degree of the first memory partition, performing fragmentation arrangement on the first memory partition. .
The system is characterized in that a certain fragment is generated during reading and writing of the system, the UFS unit is required to be subjected to defragmentation arrangement, the prior strategy is to carry out full-disk arrangement of the UFS unit at a proper time, and a large number of I/O (input/output) operations are easy to generate in full-disk arrangement, so that the system is blocked. In addition, the management logic of different types of data is different. For example, the management logic of the small file is different from that of the large file, the frequency of the small file to be defragmented is higher than that of the large file, and the small file cannot be subjected to targeted defragmentation by the traditional method.
If the fragmentation degree of the first storage partition is determined to be serious, the first storage partition can be subjected to fragmentation arrangement, so that targeted fragmentation management on the first storage partition can be realized, the efficiency of the fragmentation management can be improved, and furthermore, as the first storage partition can be subjected to independent fragmentation arrangement in time, the read-write performance of the first storage partition can be improved, namely, the read-write performance of data of a set type can be improved, and the use experience of a user can be further improved.
Wherein, the fragmentation degree can be determined according to the using time of the user using the terminal. For example, if the usage time period is greater than or equal to the first set time period (for example, 4×24 h), the first memory partition may be defragmented once by determining that the defragmentation degree of the first memory partition is serious.
The fragmentation degree can also be determined according to the interval duration after the last time of the fragmentation. For example, if the time interval from the last defragmentation of the first memory partition is greater than or equal to the second set time interval (e.g., 7 days), determining that the defragmentation degree of the first memory partition is serious, defragmenting the first memory partition again. If the time interval from the time when the user uses the terminal is greater than or equal to the second set time length, it is determined that the fragmentation degree of the first storage partition is serious, and the first time of defragmentation can be performed on the first storage partition.
The fragmentation degree may also be determined according to the amount of data written to the first memory partition. For example, if the data amount written into the first memory partition is greater than or equal to the set data amount (e.g., 20% of the total capacity of the first memory partition) after the first memory partition is defragmented last time, it is determined that the defragmentation degree of the first memory partition is serious, and the first memory partition may be defragmented once. If the data size written into the first memory partition after the user starts to use the terminal is greater than or equal to the set data size, it is determined that the first memory partition has serious fragmentation degree, and the first memory partition can be subjected to one-time defragmentation.
It should be noted that, in addition to the above manner, whether the fragmentation degree of the first memory partition is serious may be determined by other manners, which is not limited herein. In the method, targeted fragmentation management of the first storage partition can be realized, the efficiency of the fragmentation management can be improved, and the read-write performance of the first storage partition can be improved as the first storage partition can be subjected to independent fragmentation arrangement in time, namely, the read-write performance of set data (such as small files) can be improved, and the use experience of a user is further improved.
