Description
Technical Field
The application relates to a cache setting and using method in a file system of electronic equipment.
Background
The GUI (graphical user interface ) provided by the electronic device typically supports a sliding effect, i.e. when a user's finger slides on the touch screen of the electronic device, the GUI also follows the sliding together. For example, the user slides a finger to the left, the current GUI fades away following the left slide, while the new GUI also fades away following the left slide until the new GUI is fully displayed. During the sliding of the GUI, the coordinate position of the picture in the GUI may change. Every time the GUI is refreshed, the file format and binary data of the picture in the GUI need to be read, and the picture is re-rendered according to the new coordinate position. If the electronic equipment adopts a file system to store the picture, a searching method provided by the file system is needed to find the file head of the picture in the GUI from the head traversal so as to obtain the head address of binary data of the picture; and then opening the picture file, acquiring binary data of the picture, and acquiring the file format of the picture from the binary data of the picture.
Various resource files for the GUI, including picture files, audio files, video files, etc., are saved in the file system of the electronic device. Referring to fig. 1, the conventional method for using a cache setting of a file system includes the following steps.
Step S11: and traversing and searching the logical address of the file header of the resource file in the file system according to the path and the file name of the input resource file.
Step S12: and setting a first cache space in the file system, wherein the first cache space is in a linked list form. Each node in the linked list is called a cache block, and each cache block contains a plurality of first cache units. Each first buffer unit records a logical address of a header of a resource file and an offset address of a current read pointer of the resource file. However, not all resource files have corresponding first cache units, and only an opened resource file has a corresponding first cache unit. Each resource file has a read pointer, and the offset address of the current read pointer of the resource file refers to the offset between the last time the resource file was opened (read) and the first address of the resource file. If the resource file has not been opened, the offset address of the current read pointer of the resource file is zero.
Step S13: and traversing each first cache unit in each cache block from the linked list head in the first cache space according to the logic address of the file head of the input resource file.
If the offset address of the current read pointer of the resource file is found in a certain first cache unit, the first cache unit is set to the state being accessed. Meanwhile, the logical address of the file header of the resource file is used for obtaining the head address of binary data of the resource file; and adding the offset address of the current read pointer of the resource file to the head address of the binary data of the resource file to obtain the initial address of the binary data of the current access to the resource file, and reading the binary data of the required resource file in a file system from the initial address.
If the offset address of the current read pointer of the resource file cannot be found in the first cache space, the logical address of the file header of the resource file and the offset address (with an initial value of zero) of the current read pointer of the resource file are newly recorded in the available first cache unit. Meanwhile, the logical address of the file header of the resource file is used for obtaining the head address of binary data of the resource file; and adding the offset address of the current read pointer of the resource file to the head address of the binary data of the resource file to obtain the initial address of the binary data of the current access to the resource file, and reading the binary data of the required resource file in a file system from the initial address. The first cache location in the non-access state is the available first cache location. If all the first cache units in the first cache space are in the accessing state, a new cache block is applied, and all the first cache units in the new cache block are in the non-accessing state and are available first cache units.
Step S14: when a certain resource file is closed, a first cache unit corresponding to the resource file is found in the first cache space, and the first cache unit is set to be in a non-access state. When all first cache units in a certain cache block of the first cache space are in a non-access state, deleting the cache block from the linked list, and simultaneously releasing the space of the cache block.
Electronic devices typically employ flash memory (flash) as a non-volatile memory, with an SPI interface (Serial Peripheral Interface, serial external design interface). In step S11, the data needs to be read through the SPI interface, and the reading speed is slower than that of the direct-reading memory. Step S11 is very time-consuming when accessing the resource file more frequently.
Disclosure of Invention
The technical problem to be solved by the application is to provide a cache setting and using method of a file system, which can overcome the time-consuming bottleneck when the file system frequently accesses resource files.
In order to solve the technical problems, the application provides a cache setting and using method of a file system, which comprises the following steps. Step S21: setting a second cache space in the file system, wherein the second cache space comprises a plurality of second cache units; each second cache unit records a path and a file name of a resource file, a logic address of a file header of the resource file, a time overhead value of the resource file and a life cycle value of the second cache unit; the time overhead value of the resource file refers to the time spent for finding the file header of the resource file in the file system; the life cycle value of the second cache unit is used for representing the data storage life of the second cache unit; the larger the life cycle value is, the longer the data in the second buffer unit is relatively stored; and vice versa. Step S22: traversing and searching a logic address of a file header of the resource file in the second cache space according to the path and the file name of the input resource file; every time a lookup is traversed in the second cache space, the lifecycle values of all second cache units are reduced by a fixed frequency weight value. If the logical address of the file header of the resource file is found in a certain second cache unit, the second cache unit is called a matched second cache unit, and the new life cycle value of the matched second cache unit=the time overhead value of the resource file×the fixed time weight value. If the logical address of the header of the resource file is not found in all the second buffer units, the process proceeds to step S23. Step S23: and traversing and searching the logical address of the file header of the resource file in the file system according to the path and the file name of the input resource file. Step S24: storing the query result in step S23 in a second buffer unit with the minimum life cycle value, specifically including storing: the path and the file name of the resource file, the logical address of the file header of the resource file, the time overhead value of the resource file, and the initial value of the life cycle value of the second buffer unit.
Further, in the step S21, the higher the frequency of use of a certain second cache unit, the greater the query time overhead, the greater the life cycle value of the second cache unit; and vice versa.
Further, in the step S21, the capacity of the second buffer space is fixed, and includes a fixed number of second buffer units.
Further, in the step S21, when the second buffer space is insufficient, the second buffer unit with the minimum life cycle value is selected to update the record content.
Further, in the step S22, if the value of the native life cycle of a certain second cache unit-the fixed frequency weight value < the minimum value of the life cycle value, the native life cycle value of the second cache unit is kept unchanged.
Further, in the step S22, if the time overhead value x the fixed time weight value of the resource file > the maximum value of the life cycle value, the new life cycle value of the matched second cache unit=the maximum value of the life cycle value.
Further, in step S22, the life cycle value of the second cache unit which is not always matched is continuously reduced in each searching process; the life cycle value of the second cache unit matched in a certain searching process is reset to be positive; this results in a lower life cycle value for the second cache unit in which the resource file is located with a lower frequency of use, and a lower life cycle value for the second cache unit in which the resource file is located with a lower time overhead value for the same frequency of use of the resource file.
Further, in the step S24, if there are unused second cache units, the life cycle value of the unused second cache unit is smaller than that of any used second cache units, so that the second cache unit with the smallest life cycle value is selected, and an unused second cache unit is selected.
Further, in the step S24, if all the second cache units are used and there are a plurality of second cache units with the smallest life cycle value, the second cache unit with the smallest life cycle value that is queried first is selected.

Detailed Description
Referring to fig. 2, the method for using the cache setting of the file system according to the present application includes the following steps.
Step S21: and setting a second cache space in the file system, wherein the second cache space comprises a plurality of second cache units. Each second buffer unit records a path and a file name of a resource file, a logic address of a file header of the resource file, a time overhead value of the resource file and a life cycle value of the second buffer unit. Not all resource files have corresponding second cache units, and only a part of the opened resource files have corresponding second cache units.
The time overhead value of the resource file refers to the time taken to find the header of the resource file in the file system, for example in milliseconds. The minimum value of the time overhead value of the resource file is, for example, 1 millisecond.
The life cycle value of the second cache element is used to characterize the data shelf life of the second cache element. The higher the use frequency of a certain second cache unit is, the higher the inquiry time cost is, and the larger the life cycle value of the second cache unit is; and vice versa. When the second buffer space is insufficient, the second buffer unit with the minimum life cycle value is selected to update the recorded content. The greater the life cycle value, the longer the data in the second cache element is relatively saved; and vice versa. Preferably, the life cycle value of the second cache unit has a maximum value and a minimum value, and the life cycle value of the second cache unit may be a positive number, a zero number or a negative number.
Preferably, the capacity of the second buffer space is fixed, and includes a fixed number of second buffer units.
Step S22: and traversing and searching the logic address of the file head of the resource file in the second cache space according to the path and the file name of the input resource file. Every time a lookup is traversed in the second cache space, the lifecycle values of all second cache units are reduced by a fixed frequency weight value. The fixed frequency weight value is, for example, 1, and can be adjusted according to the actual application scenario. However, if the native life cycle value of a certain second cache element-the fixed frequency weight value < the minimum value of the life cycle value-the native life cycle value of that second cache element is kept unchanged.
If the logical address of the file header of the resource file is found in a certain second cache unit, the second cache unit is called a matched second cache unit, and the new life cycle value of the matched second cache unit=the time overhead value of the resource file×the fixed time weight value. The fixed time weight value is, for example, 1, and can be adjusted according to the actual application scene. However, if the time overhead value of the resource file x the fixed time weight value > the maximum value of the lifecycle value, the new lifecycle value of the matched second cache element = the maximum value of the lifecycle value. Next, steps S12 to S14 are performed. At this point, there is no need to query the file system for the logical address of the header of the resource file. When the file system is relatively large, it is significantly beneficial to save search time by the second buffer space.
If the logical address of the header of the resource file is not found in all the second cache units, the process proceeds to step S23.
Step S23: and traversing and searching the logical address of the file header of the resource file in the file system according to the path and the file name of the input resource file. Step S23 is the same as step S11.
Step S24: storing the query result in step S23 in a second buffer unit with the minimum life cycle value, specifically including storing: the path and file name of the resource file, the logical address of the file header of the resource file, the time overhead value of the resource file, and the life cycle value (initial value is 0) of the second buffer unit. Next, steps S12 to S14 are performed. In this step, if there is an unused second cache unit, after step S22, the life cycle value of the second cache unit is relatively smaller than that of any used second cache unit, so that selecting the second cache unit with the smallest life cycle value selects an unused second cache unit, and the query result of step S23 is stored in an unused second cache unit. If all the second cache units are used, selecting the second cache unit with the minimum life cycle value, deleting the original recorded content, and storing the query result in the step S23 instead. If there are a plurality of second buffer units with the minimum life cycle value, when inquiring in sequence, the second buffer unit inquired first is taken to save the inquiring result of step S23.
Various resource files for GUIs in electronic devices can be broadly divided into two categories: the first class is non-regularly updated resource files and the second class is regularly updated resource files. In practical application, the access frequency of the resource files updated in a non-timing way is not high, but the number of the resource files is large; the access frequency of the resource file updated at regular time is high. If the traditional mode of updating the earliest cache unit is adopted to treat the condition of insufficient second cache space, when the number of non-periodically updated resource files exceeds the number of the second cache units, the data of the periodically updated resource files cannot be found in the second cache space and can only be traversed and searched in a file system. The life cycle value is adopted to determine the data storage life of the second cache unit, the updating mode of the second cache space is optimized, and the problem that the second type resource files with higher access frequency are always replaced by the first type resource files with lower access frequency by the corresponding second cache unit is solved.
In step S22, the life cycle value of the second cache unit that is not matched is continuously reduced in each search process, and the new life cycle value of the second cache unit that is not matched=the new life cycle value of the second cache unit-the frequency weight value. And the life cycle value of the second cache unit matched in a certain searching process is reset to be a positive number, and the new life cycle value of the second cache unit matched=the time overhead value of the resource file x the fixed time weight value. This results in a lower life cycle value for the second cache unit in which the resource file is located with a lower frequency of use, and a lower life cycle value for the second cache unit in which the resource file is located with a lower time overhead value for the same frequency of use of the resource file. Therefore, the application combines the use frequency and the time cost value of the resource file to determine the storage life of the resource file in the second cache unit.
Referring to fig. 3, the device for setting and using a file system according to the present application includes a second buffer setting unit 21, a second buffer searching unit 22, a file system searching unit 23, and a second buffer storing unit 24. The apparatus shown in fig. 3 corresponds to the method shown in fig. 2.
The second buffer setting unit 21 is configured to set a second buffer space in the file system, where the second buffer space includes a plurality of second buffer units. Each second buffer unit records a path and a file name of a resource file, a logic address of a file header of the resource file, a time overhead value of the resource file and a life cycle value of the second buffer unit.
The second cache searching unit 22 is configured to traverse and search the logical address of the header of the resource file in the second cache space according to the path and the file name of the input resource file. Every time a lookup is traversed in the second cache space, the lifecycle values of all second cache units are reduced by a fixed frequency weight value. If the logical address of the file header of the resource file is found in a certain second cache unit, the second cache unit is called a matched second cache unit, and the new life cycle value of the matched second cache unit=the time overhead value of the resource file×the fixed time weight value. If the logical address of the header of the resource file is not found in all the second cache units, the processing is continued subsequently by the file system lookup unit 23.
The file system searching unit 23 is configured to traverse and find the logical address of the file header of the resource file in the file system according to the path and the file name of the input resource file.
The second cache storage unit 24 is configured to store the query result of the file system lookup unit 23 in a second cache unit with a minimum life cycle value, and specifically includes storing: the path and file name of the resource file, the logical address of the file header of the resource file, the time overhead value of the resource file, and the life cycle value (initial value is 0) of the second buffer unit.
The application provides a method for setting and using a second cache space in a file system, and simultaneously considers two factors of the use frequency of a second cache unit and the time cost spent on inquiring resource files in the file system to jointly determine the storage time of the files in the second cache unit. The update strategy of the second cache space enables files which are frequently accessed or files which are the same in access frequency but take more time to inquire to be stored in the second cache space for a longer time. When a certain file is repeatedly inquired, the logical address of the file header of the file can be obtained from the second cache space to a greater extent, so that time expenditure is saved, the inquiry is not required to be traversed from the file system, the inquiry efficiency is improved, and the inquiry time is shortened.
The foregoing is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and changes may be made to the present application by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application should be included in the protection scope of the present application.
