Description

Data management method, intelligent terminal and storage medium

Technical Field

The present application relates to the field of data management technologies, and in particular, to a data management method, an intelligent terminal, and a storage medium.

Background

Among the components contained in the intelligent terminal, a Central Processing Unit (CPU) is responsible for calculation, a Random Access Memory (RAM) is used as a main cache for assisting calculation, and a Read Only Memory (ROM) is used as an auxiliary storage for storing system files, application programs and data. Although RAM has a larger bandwidth than ROM, RAM has a larger unit capacity and a larger volume than ROM and is more expensive, and therefore, in recent years, a SWAP area (SWAP) technology has appeared in which RAM data is buffered in ROM, and RAM space is saved to expand main memory. And as common user data are read and written, SWAP data are written into the NAND-FLASH memory through a FLASH memory conversion layer (FTL), and the host end rewrites the logical address and then becomes junk data, and waits for system junk recovery of a file system and junk recovery of a device algorithm. For data processing, the exchange area data is the same as the processing flow of common user data, namely, the mapping state of the FTL is updated when the logical address is rewritten, the mapping state is marked as a garbage block and finally released through garbage recycling, and the reading of the middle physical address does not affect the data integrity and mapping.

In the course of conception and implementation of the present application, the inventors found that at least the following problems exist: for the SWAP data, the life cycle of the SWAP data is shorter than that of the user data, the user data is usually read many times, the SWAP data is usually read only once, and in a normal case, the SWAP data is expressed as a 4K memory page, if the two parts of data are treated indiscriminately, the SWAP data can be used as effective data to participate in garbage collection repeatedly, so that the operation smoothness and the service life of the intelligent terminal are affected.

The foregoing description is provided for general background information and does not necessarily constitute prior art.

Based on the above-mentioned mobile terminal hardware structure and communication network system, various embodiments of the present application are presented.

First embodiment

Referring to fig. 3, a data management method provided for an embodiment of the present application may be implemented by a data management device provided for an embodiment of the present application, where the data management device may be implemented in software and/or hardware, and optionally, the data management device may be a storage device in an intelligent terminal or the like. Alternatively, the intelligent terminal may be a mobile terminal in the above embodiment, and the data management device may be a memory in the above embodiment. In this embodiment, taking the execution body of the data management method as a storage device as an example, the data management method includes the following steps:

step S10: and receiving a data reading request sent by the host side and used for reading target data.

Optionally, after the storage device establishes a communication connection with the host end in the intelligent terminal, the data reading request sent by the host end for reading the target data may be received in real time or at preset time intervals. The host side may be a device or a device for data processing, such as a processor in an intelligent terminal, and the target data may be any data stored in a storage device, and the data reading request may carry a logical address of the target data.

Step S20: and when the target data is exchange area data, marking the state of the target data as invalid.

Optionally, after receiving the data reading request sent by the host, the storage device detects whether the target data to be read in the data reading request is exchange area data, if the target data is determined to be exchange area data, the state of the target data can be marked as invalid after the target data is read, so that the target data is not moved when the invalid space is recovered in the garbage collection process, thereby reducing write amplification, and reducing garbage collection frequency due to reduction of effective data amount of movement, and further improving operation smoothness of the intelligent terminal. Alternatively, the storage device may mark the state of the target data as invalid prior to performing the garbage collection operation.

Optionally, the marking the state of the target data as invalid includes: and deleting the mapping relation corresponding to the target data in the data mapping table. Optionally, the content stored in the data mapping table is a mapping relationship from a logical address to a physical address, the data mapping table is queried by using the logical address (a relative address used in a user program), a corresponding physical address (an absolute address of an actual storage unit) is found, and then read-write access is performed on the actual storage unit to obtain corresponding data. After deleting the mapping relation corresponding to the target data in the data mapping table, the mapping from the logical address of the target data to the corresponding physical address is disconnected, so that the target data cannot be read continuously, and the target data cannot be moved when the dead space is recovered in the garbage recovery process. Alternatively, the mapping relationship corresponding to the deleted data may be understood as that mapping from a logical address to a physical address of the data is disconnected, for example, the physical address of the data recorded in the data mapping table may be replaced by an undefined symbol or the like.

Optionally, the target data is exchange area data, including at least one of the following: the data reading request comprises a preset identifier; the target data is located in a preset storage area. Optionally, the storage device may detect whether the target data is the switching area data by determining whether the data reading request includes a preset identifier and/or whether the target data is located in a preset storage area, and if the data reading request includes the preset identifier and/or the target data is located in the preset storage area, may determine that the target data is the switching area data. Optionally, the preset identifier may be set according to actual situation, for example, may be set to "0" or "1", and the preset identifier may be directly included in a read instruction corresponding to the data read request, for example, assuming that the size of the read instruction is 2 bytes, that is, 16 bits, then the 16 th bit may be used as an identifier bit, if the identifier bit is "1", it indicates that the data read request includes the preset identifier, and if the identifier bit is not "1", it indicates that the data read request does not include the preset identifier. Optionally, the preset storage area may be a virtual memory or the like. Therefore, whether the data are the data of the exchange area can be rapidly and accurately judged, and the operation fluency of the intelligent terminal is further improved.

Optionally, assuming that the host sends a data write request to the storage device, where the data write request is used to request to write the target data "data.doc" with the logical address a, if the data write request specifies that the target data is written into the preset storage area "virtual memory a", the target data may be written into the virtual memory a, and the address B of the target data in the virtual memory a, that is, the physical address of the target data, is written into the a location a in the data mapping table. After receiving the data reading request for reading the target data "data.doc", the virtual memory a belongs to the switching area, after the target data "data.doc" is read, the data in the a-th position in the data mapping table can be changed into invalid data, such as undefined symbols, so as to realize deleting the mapping relation corresponding to the target data "data.doc" in the data mapping table.

and receiving a data writing request which is sent by the host side and used for writing the target data, wherein the data writing request comprises writing in the preset storage area and/or the preset identifier.

Alternatively, the host may send a data write request to the storage device to store the data in the storage device, and alternatively, the storage device may receive the data write request sent by the host. After receiving a data writing request sent by a host end and used for writing the target data, the storage device writes the target data into a preset storage area based on the fact that the data writing request comprises a writing preset storage area and/or a preset identifier. Optionally, the storage device may also store the target data to which the preset identifier is added. Therefore, the data writing request is used for writing the data in the exchange area, the data in the exchange area can be conveniently read later, and the operation is convenient.

In summary, in the data management method provided in the foregoing embodiment, after the read data is the interaction area data, the state of the data is marked as invalid in time, so that the data is not moved when the invalid space is recovered in the garbage recovery process, thereby improving the operation smoothness of the intelligent terminal and prolonging the service life.

Optionally, before marking the state of the target data as invalid when the target data is exchange area data, the method further includes: receiving a configuration instruction sent by the host, wherein the configuration instruction is used for indicating to start a data management function; and responding to the configuration instruction, starting the data management function to detect whether the target data is the exchange area data after receiving the data reading request.

Optionally, the user may set whether to start the data management function through the host side, and after the user determines to start the data management function, the host side may send a configuration instruction for indicating to start the data management function to the storage device, optionally, the storage device receives the configuration instruction sent by the host side, and in response to the configuration instruction, starts the data management function, so as to detect whether the target data is the switch area data after receiving the data reading request. The data management function may be regarded as a function of marking the state of the data as invalid after the data is read again when the read data is the exchange area data. Therefore, after receiving the configuration instruction for indicating to start the data management function, whether the data to be read is the data of the exchange area is detected, so that the operation smoothness of the intelligent terminal is further improved, and the service life of the intelligent terminal is prolonged.

Second embodiment

Based on the same inventive concept as the above embodiment, a detailed description will be given below by way of a specific example. In this example, taking the HOST side as HOST, the storage Device as Device, the target data as a, the exchange area data as ROD area data, and marking the state of the target data as invalid as marking the state of the target data as an invalid block as an example.

Referring to fig. 4, fig. 4 (a) is a schematic diagram of data management by using the conventional data management method, as can be seen from fig. 4 (a), after sending a data writing request for writing data a and B into the ROD area to a Device to write data a and B into the ROD area in the Device, if a data reading request for reading data a is sent to the Device, the Device still uses valid data after reading data a from the ROD area in response to the data reading request, so that the Device needs to move data a and B during subsequent garbage collection (GC, garbage Collector), and invalid data blocks exist when rewriting data a, which not only causes resource waste, but also affects the smoothness of operation of the terminal. Fig. 4 (B) is a schematic diagram of data management performed by the data management method according to the present application, comparing the data management process performed by the data management method according to the present application with the fact that, in the HOST, by sending a data write request for writing data a and B into the ROD area to the Device, after writing the data a and B into the ROD area in the Device, if a data read request for reading the data a is sent to the Device, the Device reads the data a from the ROD area in response to the data read request, and sends the data a to the HOST, since it is detected that the data a is located in the ROD area, the Device marks the data a as an invalid block after reading the data a, i.e. the physical address of the data a recorded in the data mapping table is replaced with an undefined symbol, so as to break the mapping from the logical address to the physical address of the data a, so that the Device only needs to move the data B when the subsequent garbage is recovered, without moving the data B, thereby reducing the effective data amount and the frequency of garbage recovery, and saving the storage space when the data a is rewritten.

Third embodiment

Referring to fig. 5, a data management method provided in an embodiment of the present application may be suitable for a case of managing data reading, where the method may be performed by a data management device provided in an embodiment of the present application, and the device may be implemented in a software and/or hardware manner, and optionally, the data management device may be specifically a host side in an intelligent terminal, etc. Alternatively, the intelligent terminal may be a mobile terminal in the above embodiment, and the data management device may be a processor in the above embodiment. In this embodiment, taking the execution body of the method as a host, the data management method includes the following steps:

step S30, responding to the request for acquiring the target data.

Optionally, the host may receive a request for acquiring target data sent by other terminal devices or other components of the intelligent terminal where the host is located due to operation requirements, or may be a request for acquiring target data triggered by the host due to operation requirements. The host side may be a device or means for data processing, such as a processor in a smart terminal or the like. The other terminal device may be a wireless mouse, an in-vehicle device, or the like, which is communicatively connected to the host side. Other components of the intelligent terminal may be a display unit, a user input unit, etc.

Step S40, a data reading request for reading the target data is sent to the storage device.

Optionally, when determining that the target data needs to be acquired, the host side sends a data reading request for reading the target data to the storage device so as to request the storage device to return the target data. The target data may be any data stored in the storage device, and the data read request may carry a logical address of the target data.

Optionally, before the responding to the request for obtaining the target data, the method further includes: and in response to the need of writing the target data, sending a data writing request for writing the target data to the storage device when the target data is determined to be required to be stored in the exchange area, wherein the data writing request comprises a writing preset storage area and/or a preset identification.

Optionally, the host side firstly detects whether the target data needs to be stored in the exchange area in response to the need of writing the target data into the storage device, and when determining that the target data needs to be stored in the exchange area, sends a data writing request for writing the target data to the storage device, wherein the data writing request comprises a writing preset storage area and/or a preset identifier, so that the storage device stores the target data in the preset storage area according to the data writing request, thereby realizing the writing of the data in the exchange area, facilitating the subsequent reading of the data in the exchange area, and being convenient to operate. Optionally, the preset identifier may be set according to actual situation, for example, may be set to "0" or "1", and the preset identifier may be directly included in a read instruction corresponding to the data read request, for example, assuming that the size of the read instruction is 2 bytes, that is, 16 bits, then the 16 th bit may be used as an identifier bit, if the identifier bit is "1", it indicates that the data read request includes the preset identifier, and if the identifier bit is not "1", it indicates that the data read request does not include the preset identifier. Optionally, the preset storage area may be a virtual memory or the like.

Optionally, the method further comprises: transmitting a configuration instruction to the storage device in response to an opening operation for a data management function, so that the storage device opens the data management function; and/or outputting prompt information for prompting support or starting of the data management function; and outputting prompt information of starting the data management function.

Alternatively, the user may set whether to start the data management function through the host side, and after the user determines to start the data management function, the host side will send a configuration instruction to the storage device in response to a start operation for the data management function, so that the storage device starts the data management function. Referring to fig. 6, a suspension button may be displayed on the display interface of the intelligent terminal, as shown in fig. 6 (a), and the suspension button is used to display control options of the data management function after being triggered, and the user may select the corresponding control options by clicking or the like to select to turn on or off the data management function, as shown in fig. 6 (b). The data management function may be regarded as a function of marking the state of the data as invalid after the data is read again when the data read by the storage device is the exchange area data. Optionally, the host end can also output prompt information for prompting support or starting of the data management function, so that a user can select conveniently based on requirements, and user experience is improved. Optionally, the host may also output a prompt message that the data management function has been turned on.

In summary, in the data management method provided in the foregoing embodiment, in response to a request for obtaining target data, a data reading request for reading the target data is sent to a storage device, so that after the storage device reads that the data is interaction area data, the storage device marks the state of the data as invalid in time, so that the data is not moved when the invalid space is recovered in the garbage recovery process, thereby improving the operation smoothness of the intelligent terminal and prolonging the service life.

Fourth embodiment

Based on the same inventive concept as the above embodiments, referring to fig. 7, a data management method provided for an embodiment of the present application includes the following steps:

step S50: the host side responds to a request for acquiring target data and sends a data reading request for reading the target data to the storage device.

Alternatively, the host side may be a device or means for data processing, such as a processor in a smart terminal or the like. Optionally, the host may receive a request for acquiring target data sent by other terminal devices or other components of the intelligent terminal where the host is located due to operation requirements, or may be a request for acquiring target data triggered by the host due to operation requirements. The other terminal device may be a wireless mouse, an in-vehicle device, or the like, which is communicatively connected to the host side. Other components of the intelligent terminal may be a display unit, a user input unit, etc. The target data may be any data stored in the storage device, and the data read request may carry a logical address of the target data.

Optionally, when determining that the target data needs to be acquired, the host side sends a data reading request for reading the target data to the storage device so as to request the storage device to return the target data.

Step S60: and the storage equipment receives the data reading request sent by the host.

Optionally, after the storage device establishes a communication connection with the host side, a data reading request sent by the host side for reading target data may be received in real time or at preset time intervals.

Step S70: and when the target data is exchange area data, the storage device marks the state of the target data as invalid.

Optionally, after receiving the data reading request sent by the host, the storage device detects whether the target data to be read in the data reading request is exchange area data, if the target data is determined to be exchange area data, the state of the target data can be marked as invalid after the target data is read, so that the target data is not moved when the invalid space is recovered in the garbage collection process, thereby reducing write amplification, and reducing garbage collection frequency due to reduction of effective data amount of movement, and further improving operation smoothness of the intelligent terminal. Meanwhile, the storage device can send the target data to the host side. Alternatively, the storage device may mark the state of the target data as invalid prior to performing the garbage collection operation.

Optionally, the method further comprises: the host side responds to the requirement of writing the target data, and when determining that the target data is required to be stored in a switching area, sends a data writing request for writing the target data to the storage equipment, wherein the data writing request comprises a writing preset storage area and/or a preset identifier; and the storage equipment receives a data writing request which is sent by the host side and used for writing the target data.

Optionally, the host side firstly detects whether the target data needs to be stored in the exchange area in response to the need of writing the target data into the storage device, and when determining that the target data needs to be stored in the exchange area, sends a data writing request for writing the target data to the storage device, wherein the data writing request comprises a writing preset storage area and/or a preset identifier, so that the storage device stores the target data in the preset storage area according to the data writing request, thereby realizing the writing of the data in the exchange area, facilitating the subsequent reading of the data in the exchange area, and being convenient to operate. Alternatively, the storage device may receive a data write request correspondingly sent by the host side. After receiving a data writing request sent by a host end and used for writing the target data, the storage device writes the target data into a preset storage area based on the fact that the data writing request comprises a writing preset storage area and/or a preset identifier. Optionally, the storage device may also store the target data to which the preset identifier is added. Therefore, the data writing request is used for writing the data in the exchange area, the data in the exchange area can be conveniently read later, and the operation is convenient.

Optionally, the method further comprises: the host side responds to the starting operation of the data management function and sends a configuration instruction to the storage device, wherein the configuration instruction is used for indicating the storage device to start the data management function; and the storage equipment responds to the configuration instruction, and starts the data management function so as to detect whether the target data is the switching area data after receiving the data reading request.

Optionally, the user may set whether to start the data management function through the host side, and after the user determines to start the data management function, the host side may send a configuration instruction for indicating to start the data management function to the storage device, and correspondingly, the storage device receives the configuration instruction sent by the host side, and starts the data management function in response to the configuration instruction, so as to detect whether the target data is the switch area data after receiving the data reading request. The data management function may be regarded as a function of marking the state of the data as invalid after the data is read again when the read data is the exchange area data. Therefore, after receiving the configuration instruction for indicating to start the data management function, whether the data to be read is the data of the exchange area is detected, so that the operation smoothness of the intelligent terminal is further improved, and the service life of the intelligent terminal is prolonged.

Optionally, the method further comprises: and outputting prompt information for prompting supporting or starting the data management function.
