[0002] Buffer is a memory area in a computer system used to temporarily store data. Its main function is to improve data processing efficiency and solve the speed difference between data producers and consumers.
[0003] Most software will allocate a cache when running to pass data between functions. As the size and complexity of software grows, cache usage also increases. There may be a large amount of dirty data in the cache, resulting in a waste of memory resources. Alternatively, only a fixed-size cache is allocated to the software, and the version needs to be upgraded again when a new scenario appears, resulting in poor compatibility.

[0048] The exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the accompanying drawings, it should be understood that the present disclosure can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present disclosure and to fully convey the scope of the present disclosure to those skilled in the art.
[0049] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.
[0050] In addition, the terms "first" and "second" etc. are used to distinguish different objects, rather than to describe a specific order. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units that are not listed, or may optionally include other steps or units that are inherent to these processes, methods, products or devices.
[0051] Please refer to Figure 1 , Figure 1 1 is a flowchart of a software cache management method provided by an embodiment of the present application. The present application can be applied to a terminal. The method includes the following steps S101 to S104:
[0052] S101. Create a cache area including a plurality of fixed-size data areas according to a received cache area creation request, and record a data area number and status information of each of the data areas;
[0053] The cache creation request includes the type and length of the commonly used data of the software. The size of the data area can be set with reference to the length of the commonly used data of the software, and the number of data areas can be determined with reference to the number of commonly used data of the software.
[0054] The state information includes the usage state, the data type and data length of the stored data, and a timestamp. The data type includes single-use data, multiple-use data, and long-term valid data.
[0055] The usage status of the data area can be occupied or unoccupied. Unoccupied means it is an idle data area where data can be written.
[0056] The timestamp indicates the time of operations such as writing data, reading data, or clearing data in the data area. The expired cache can be determined based on the timestamp, and the difference between the timestamp in the data area and the current time can be determined. If it exceeds the preset time range, it will be marked as invalid data, the invalid data will be cleared, and the timestamp will be updated.
[0057] In this application, a cache area is pre-opened. When the cache area is created, N fixed-size data areas are preset to store commonly used data. It is not necessary to apply for memory every time data is stored, which reduces the frequent application of memory. Figure 2 The figure shows a distribution diagram of the data area pre-created in the present application, wherein NO represents the data area number; STATE represents the usage status of the data area, USED represents occupied, and NULL represents unoccupied; TYPE represents the data type of the stored data; DATALEN represents the data length of the stored data, and DATA represents the stored data.
[0058] S102, when receiving a write cache request, writing data into the cache area according to the status information of each data area in the cache area;
[0059] Specifically, the above step S102 can be implemented as follows: based on the status information of each data area in the cache area, determine whether there is an available data area in the cache area; if there is no available data area at present, apply for new memory as a new data area, write data into the new data area, and record the data area number and status information of the new data area; if there is an available data area at present, write the data into the available data area, and update the timestamp in the data area after successful writing.
[0060] When writing to the cache, this application will first store the already opened and free data area. If there is no free data area available, it will apply for new memory as a new data area, mark the usage status as occupied, and record the data area number. Each write will update the timestamp in the data area. It can be seen that this application has both pre-opened data areas to meet known scenarios and can dynamically create new data areas to meet future scenario needs.
[0061] S103, when receiving a cache read request, reading data from the cache area according to the data area number and status information of each data area in the cache area;
[0062] Specifically, the above step S103 can be implemented as follows: reading data from the corresponding data area in the cache area according to the data area number and data type, and updating the timestamp in the data area after the reading is successful.
[0063] When reading data, the application obtains the corresponding data according to the data area number and data type, distinguishes between single reading and multiple reading, and updates the timestamp in the data area for each reading. The data reading process also includes checking the data type and validity, and determining the length of the cached data.
[0064] S104: Manage the cache area according to the status information of each data area in the cache area.
[0065] Specifically, the above step S104 can be implemented as follows:
[0066] For single-use data in a data area, the data area is cleared after reading, and the timestamp in the data area is updated;
[0067] For the data in the data area that is used multiple times, an available number is set. When the available number is zero, the data area is cleared and the timestamp in the data area is updated;
[0068] For each data area, determine the difference between the timestamp in the data area and the current time. If the difference exceeds the preset time range, clear the data area and update the timestamp in the data area. For example, for long-term valid data, wait until the invalid mark is shown before clearing the data, and update the timestamp after clearing.
[0069] If the data area is a new data area created by applying for new memory and is not occupied, the difference between the timestamp in the new data area and the current time is determined, and if the difference exceeds the preset time range, the new data area is released. It can be seen that this application can release memory in time.
[0070] The software cache management method provided in the embodiment of the present application creates a cache including multiple fixed-size data areas according to the received cache creation request, and records the data area number and status information of each data area; when receiving a write cache request, writes data into the cache according to the status information of each data area in the cache; when receiving a read cache request, reads data from the cache according to the data area number and status information of each data area in the cache; manages the cache according to the status information of each data area in the cache; wherein the status information includes the usage status, the data type and data length of the stored data, and the timestamp, and the data type includes single-use data, multiple-use data, and long-term valid data. Compared with the prior art, the present application pre-opens a cache data area, distinguishes the timing of clearing the data area and releasing the memory, avoids frequent memory application, can release the memory in time, and reduces the occupation of resources.
