[0005] Identify the main memory and flash memory of electronic devices; the main memory includes a dynamic memory area.

[0006] When the free capacity of the dynamic memory area is detected to be less than a preset threshold, the first stored data in the dynamic memory area is compressed into the preset compressed memory area in the main memory.

[0007] According to a preferred embodiment of the present invention, the method further includes:

[0008] Periodically acquire free bytes from the dynamic memory area according to a preset time period;

[0009] Calculate the duration for which idle bytes remain idle;

[0010] Identify the minimum length of newly added cached data in the dynamic memory area;

[0011] If the duration exceeds the preset duration and the length of the free bytes is less than the minimum length, the free bytes will be identified as memory fragments.

[0012] Call the preset interface to perform memory fragmentation reclamation.

[0013] According to a preferred embodiment of the present invention, the method further includes:

[0014] Get the lower limit of the dynamic memory area's capacity;

[0015] The upper limit of capacity is obtained by multiplying the lower limit of capacity by the preset ratio.

[0016] Generate a preset range based on the lower and upper capacity limits;

[0017] The preset threshold is adjusted periodically based on the preset range.

[0018] According to a preferred embodiment of the present invention, compressing the first stored data in the dynamic memory area to a preset compressed memory area in the main memory specifically includes:

[0019] Based on the preset mapping table, determine the occupied capacity of the preset compressed memory area;

[0020] The first stored data is extracted from the dynamic memory area based on the occupied capacity;

[0021] The first stored data is compressed to obtain compressed data;

[0022] Transfer the compressed data to the preset compressed memory area.

[0023] According to a preferred embodiment of the present invention, the method further includes: transferring a second storage data in a dynamic memory region to a preset swap memory region in a flash memory, including:

[0024] Calculate the amount of data in the second storage area;

[0025] A transmission thread is obtained from a preset thread pool based on the amount of data.

[0026] The target byte is determined from the preset swap memory area, corresponding to the amount of data.

[0027] Invoke the transmission thread to transfer the second storage data to the target byte for storage.

[0028] According to a preferred embodiment of the present invention, the method further includes:

[0029] If the execution frequency and number of executions of data stored in the dynamic memory area are less than the preset frequency and number of executions, the data will be identified as the target data.

[0033] The target data is transferred to the preset swap memory area.

[0034] On the other hand, the present invention also proposes a dynamic memory intelligent expansion device, which operates in electronic devices. The dynamic memory intelligent expansion device includes:

[0035] An identification unit is used to identify the main memory and flash memory of an electronic device, wherein the main memory includes a dynamic memory area;

[0036] The compression unit is used to compress the first stored data in the dynamic memory area to a preset compressed memory area in the main memory when the free capacity of the dynamic memory area is detected to be less than a preset threshold.

[0037] On the other hand, the present invention also proposes an electronic device, the electronic device comprising:

[0038] Memory, which stores computer-readable instructions; and

[0039] A processor executes computer-readable instructions stored in memory to enable a dynamic and intelligent method of memory expansion.

[0040] On the other hand, the present invention also proposes a computer-readable storage medium storing computer-readable instructions, which are executed by a processor in an electronic device to realize a dynamic memory intelligent expansion method.

[0041] As can be seen from the above technical solutions, when the free capacity is detected to be less than a preset threshold, this application can increase the total capacity of the dynamic memory area by compressing the first storage data and transmitting the second storage data to the preset swap memory area. By actively releasing the target occupied dynamic area, the utilization efficiency of the dynamic memory area can be improved, and memory fragments can be periodically recycled. Under the condition of limited hardware resources, this application can effectively solve the problems of resource shortage in the dynamic memory area and high cost of electronic devices due to the high cost of dynamic memory by combining multiple dimensions.

[0046] Figure 5 This is a schematic diagram of the structure of an electronic device that implements a preferred embodiment of the intelligent dynamic memory expansion method of the present invention. Detailed Implementation

[0047] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0048] like Figure 1 The diagram shown is a flowchart of a preferred embodiment of the dynamic memory intelligent expansion method of the present invention. The order of the steps in this flowchart can be changed, and some steps can be omitted, depending on different requirements.

[0049] The dynamic memory intelligent expansion method is applied to one or more electronic devices. An electronic device is a device that can automatically perform numerical calculations and / or information processing according to pre-set or stored computer-readable instructions. Its hardware includes, but is not limited to, microprocessors, application-specific integrated circuits (ASICs), field-programmable gate arrays (FPGAs), digital signal processors (DSPs), embedded devices, etc.

[0050] Electronic devices can be any electronic product that allows human-computer interaction, such as personal computers, tablets, smartphones, personal digital assistants (PDAs), game consoles, interactive network television (IPTV), smart wearable devices, etc.

[0051] Electronic devices may include network devices and / or user devices. Among them, network devices include, but are not limited to, single network electronic devices, groups of electronic devices consisting of multiple network electronic devices, or cloud computing-based clouds consisting of a large number of hosts or network electronic devices.

[0052] The networks in which electronic devices are located include, but are not limited to: the Internet, wide area networks (WANs), metropolitan area networks (MANs), local area networks (LANs), and virtual private networks (VPNs).

[0053] 101 identifies the main memory and flash memory of an electronic device, with the main memory including the dynamic memory area.

[0054] In at least one embodiment of the present invention, the electronic device may be a smart home product, such as home appliances, lighting systems, smart central control screen switches, etc.

[0055] Main memory is the internal memory that directly exchanges data with the CPU. Main memory is usually used as a temporary data storage medium for the operating system or other running programs of electronic devices.

[0056] Flash memory, also known as flash storage, is a type of storage chip that allows data to be modified through specific programs.

[0057] Dynamic memory refers to the RAM capacity in main memory that users can specify for the startup of a virtual operating system.

[0058] In at least one embodiment of the present invention, the electronic device identifies the main memory and flash memory of the electronic device, specifically including:

[0059] The memory of type 1 in the electronic device is designated as main memory, and the memory of type 2 is designated as flash memory.

[0060] The first type of memory can write or read information from any specified address at any time.

[0061] The second type of memory will not lose data due to power failure.

[0062] The memory type allows for accurate identification of main memory and flash memory.

[0063] 102. When the free capacity of the dynamic memory area is detected to be less than the preset threshold, the first stored data in the dynamic memory area is compressed into the preset compressed memory area in the main memory.

[0064] In at least one embodiment of the present invention, the preset threshold is a parameter value obtained by periodic adjustment.

[0065] The first stored data can be any data stored in the dynamic memory area. The preset compressed memory area refers to a memory region pre-defined in the main memory of an electronic device. Generally, the capacity of the preset compressed memory area does not exceed 10% of the main memory capacity. Data in the preset compressed memory area, because it has undergone compression processing, can be read at high speed. For example... Figure 2 As shown, Figure 2 The large square in the middle is the main storage. Figure 2 The small square in the image represents the preset compressed memory area.

[0066] In at least one embodiment of the present invention, the method further includes:

[0067] Get the lower limit of the dynamic memory area's capacity;

[0068] The upper limit of capacity is obtained by multiplying the lower limit of capacity by the preset ratio.

[0069] Generate a preset range based on the lower and upper capacity limits;

[0070] The preset threshold is adjusted periodically based on the preset range.

[0071] The lower limit of capacity can be set via the kernel option / proc / sys / vm / min_free_kbytes.

[0072] The preset ratio can be set according to actual needs; for example, the preset ratio can be 2.5.

[0073] By controlling the preset threshold within a preset range, it is possible to avoid frequent data compression and clearing due to setting the preset threshold too high, and also to avoid a small available dynamic memory area due to setting the preset threshold too low. This improves the rationality of the preset threshold setting. By periodically adjusting the preset threshold, resource balance of electronic devices can be achieved.

[0074] In at least one embodiment of the present invention, the electronic device compresses first stored data in a dynamic memory area to a preset compressed memory area in the main memory, specifically including:

[0075] Based on the preset mapping table, determine the occupied capacity of the preset compressed memory area;

[0076] The first stored data is extracted from the dynamic memory area based on the occupied capacity;

[0077] The first stored data is compressed to obtain compressed data;

[0078] Transfer the compressed data to the preset compressed memory area.

[0079] The preset mapping table stores the mapping relationship between multiple preset memory areas and their corresponding bytes.

[0080] By extracting the first storage data from the occupied capacity, a reasonable amount of storage data can be extracted, avoiding data loss due to the inability to store compressed data in the occupied bytes.

[0081] Specifically, the electronic device determines the occupied capacity of the preset compressed memory area based on a preset mapping table, including:

[0082] Retrieve the bytes occupied by the preset compressed memory area from the preset mapping table;

[0083] Calculate the occupied capacity based on the number of bytes occupied.

[0084] By using a pre-defined mapping table, the occupied bytes can be quickly obtained, improving the efficiency of determining the occupied capacity.

[0085] In other embodiments, the size of the occupied capacity can be set according to different business needs.

[0086] In other embodiments, the electronic device stores compressed data and first storage data in a preset swap memory area in flash memory.

[0087] In at least one embodiment of the present invention, the electronic device reclaims memory fragments in the dynamic memory area according to a preset time period.

[0088] The preset time can be set according to actual needs. Memory fragmentation refers to all unusable free memory in an electronic device.

[0089] In at least one embodiment of the present invention, the electronic device reclaims memory fragments in the dynamic memory area according to a preset time period, specifically including:

[0090] Periodically acquire free bytes from the dynamic memory area according to a preset time period;

[0091] Calculate the duration for which idle bytes remain idle;

[0092] Identify the minimum length of newly added cached data in the dynamic memory area;

[0093] If the duration exceeds the preset duration and the length of the free bytes is less than the minimum length, the free bytes will be identified as memory fragments.

[0094] Call the preset interface to perform memory fragmentation reclamation.

[0095] Among them, the duration refers to the difference between the acquisition time of the free byte and the release time of the free byte. The release time refers to the point in time when the data is cleared from the free byte, and the acquisition time refers to the point in time when the free byte is acquired from the dynamic memory area.

[0096] New cached data refers to the data information processed by the electronic device during the period from the time of release to the time of acquisition.

[0097] The preset duration can be set according to actual needs; for example, the preset duration can be 1 hour.

[0098] The default interface can be the kernel-mode shrinker interface.

[0099] By combining the comparison between the duration and the preset duration, and the comparison between the length of the free byte and the minimum length, it is possible to avoid the free byte being mistakenly designated as memory fragment because it cannot be occupied in a short period of time, thereby improving the rationality of memory fragment identification and the rationality of periodic memory fragment reclamation.

[0100] In at least one embodiment of the present invention, a second storage data in a dynamic memory area is transferred to a preset swap memory area in a flash memory.

[0101] In at least one embodiment of the present invention, the second stored data is typically data that has not been used recently in the dynamic memory area. The second stored data can be determined by comparing the data read time corresponding to the stored data in the dynamic memory area with the configuration time period.

[0102] Pre-defined swap memory refers to a memory area that an electronic device pre-configures in its flash memory. For example... Figure 3 As shown, Figure 3 The large box in the image represents the flash memory. Figure 2 The small square in the image represents the default swap memory area.

[0103] In at least one embodiment of the present invention, transferring the second storage data in the dynamic memory area to a preset swap memory area in the flash memory specifically includes:

[0104] Calculate the amount of data in the second storage area;

[0105] A transmission thread is obtained from a preset thread pool based on the amount of data.

[0106] The target byte is determined from the preset swap memory area, corresponding to the amount of data.

[0107] Invoke the transmission thread to transfer the second storage data to the target byte for storage.

[0108] Among them, the transmission thread refers to the number of idle threads in the preset thread pool that is configured. The configured number is determined based on the amount of data and the data transmission efficiency of the idle threads.

[0109] The target byte refers to the byte region in the preset swap memory area that corresponds to the amount of data.

[0110] Identifying the target byte by the amount of data can prevent data loss during the transmission of the second storage data. Transmitting the second storage data through a transmission thread can achieve fast transmission of the second storage data without consuming the resources of the electronic device.

[0111] In at least one embodiment of the present invention, the method further includes:

[0112] If the execution frequency and number of executions of data stored in the dynamic memory area are less than the preset frequency and number of executions, the data will be identified as the target data.

[0113] Clear the target data from the dynamic memory area.

[0114] The target data refers to the stored data in the dynamic memory area whose execution frequency is less than the preset frequency and whose execution count is less than the preset count.

[0115] Execution frequency refers to the number of times an electronic device reads stored data per unit of time. Execution count refers to the total number of times stored data is read from the dynamic memory area.

[0116] The preset frequency and preset number of times can be set according to actual needs.

[0117] By combining the comparison between the execution frequency and the preset frequency, as well as the comparison between the number of executions and the preset number of executions, the target data can be accurately determined, thereby improving the rationality of the generation of the target occupying the dynamic area.

[0118] Specifically, the electronic device clears the target data from the dynamic memory area, including:

[0119] Call the preset deletion thread to clear the target data; or

[0120] The target data is transferred to the preset swap memory area.

[0121] The above implementation methods can achieve the removal of target data based on a variety of different removal methods.

[0122] The main memory in this invention includes, but is not limited to: a first dynamic area occupied by first stored data in a dynamic memory area, a second dynamic area occupied by second stored data in a dynamic memory area, and a target dynamic area occupied by target stored data in a dynamic memory area.

[0123] In at least one embodiment of the present invention, the electronic device completes the resource expansion of the dynamic memory area based on memory fragmentation and the release of storage space of the first occupied dynamic area, the second occupied dynamic area and the target occupied dynamic area.

[0124] In at least one embodiment of the present invention, memory fragments, a first occupied dynamic area, a second occupied dynamic area, a target occupied dynamic area, a preset compressed memory area, and a second occupied dynamic area can all be used as extended areas of the dynamic memory area.

[0125] As can be seen from the above technical solutions, when the free capacity is detected to be less than a preset threshold, this application can increase the total usable capacity of the dynamic memory area by compressing the first stored data and transferring the second stored data to a preset swap memory area. By actively releasing the target occupied dynamic area, the utilization efficiency of the dynamic memory area can be improved, and memory fragmentation can be periodically reclaimed. Under limited hardware resources, this approach effectively solves the resource shortage problem of the dynamic memory area by combining multiple dimensions. Furthermore, since dynamic memory is relatively expensive, solving the dynamic memory resource shortage problem can also reduce the cost of electronic devices, thereby enhancing the long-term competitiveness of electronic device products.

The module / unit referred to in this invention refers to a series of computer-readable instruction segments that can be acquired by the processor 13 and perform a fixed function, and which are stored in the memory 12. In this embodiment, the functions of each module / unit will be described in detail in subsequent embodiments.

[0127] The identification unit 110 identifies the main memory and flash memory of the electronic device, the main memory including a dynamic memory area.

Figure 2 As shown, Figure 2 The large square in the middle is the main storage. Figure 2 The small square in the image represents the preset compressed memory area.

[0141] The calculation unit 117 calculates the product of the lower limit of capacity and the preset ratio to obtain the upper limit of capacity;

[0142] Generation unit 118 generates a preset range based on the lower capacity limit and the upper capacity limit;

[0143] The execution unit 115 periodically adjusts the preset threshold according to the preset range.

[0144] The lower limit of capacity can be set via the kernel option / proc / sys / vm / min_free_kbytes.

[0145] The preset ratio can be set according to actual needs; for example, the preset ratio can be 2.5.

[0159] In other embodiments, the compression unit 112 stores the compressed data and the first storage data in a preset swap memory area in the flash memory.

[0160] In at least one embodiment of the present invention, the recycling unit 111 recycles memory fragments in the dynamic memory area according to a preset time period.

[0161] The preset time can be set according to actual needs. Memory fragmentation refers to all unusable free memory in an electronic device.
