Data storage system and method

The present invention relates to a data storage system and method, and more particularly to a data storage system and method for use in a mobile device.

Adding or receiving a data (such as a newsletter or MMS) to a mobile device often encounters a limitation of memory resources (ie, the storage space is full), and requires the user to delete some old data so that new data can be stored. stand up. However, if the user does not release the resource in time, for example, if a call comes in and needs to be answered, the last data needs to be stored before the call is received, otherwise data loss will occur.

The traditional practice is to add an additional temporary storage space, first store the new data in the temporary storage space, but the maintenance of the temporary storage space is quite cumbersome afterwards. For example, when there is a need to read or modify data, it must be judged whether the data is in the temporary storage space or the memory before the operation can be performed, and the deleted data needs to be copied to the memory before deleting the data of the temporary storage space. To maintain the integrity of the data.

In view of the above, it is necessary to provide a data storage system and method. When a mobile device receives a new data, it can automatically store the new data and facilitate subsequent data processing.

A data storage system is applied to a mobile device, the system comprising: a memory initialization module, configured to initialize a memory when the mobile device is activated; and a memory reservation module, configured to reserve in the memory An empty piece a data storage module for automatically storing the new data in a reserved memory space when the mobile device receives a new data; the memory reservation module is further used in the memory Re-reserving a space and determining whether the reserved memory space is successful; the prompting module is configured to prompt the user to release the memory when the reserved memory space fails; the memory reservation module is also used for It is judged whether the user releases the memory successfully. If the user fails to release the memory, it is further determined whether the number of prompts is reached.

A data storage method is applied to a mobile device, the method comprising the steps of: initializing a memory when the mobile device is activated; reserving a space in the memory; automatically receiving the new data when the mobile device receives a new data The data is stored in the reserved memory space, and a space is reserved in the memory; when the memory space fails to be reserved, the user is prompted to release the memory, and if the user releases the memory successfully, then the data is A space is reserved in the memory. If the user fails to release the memory, the user is prompted to release the memory until the number of prompts is reached.

Compared with the prior art, the data storage system and method can reserve a space in the mobile device memory, and when the mobile device receives a new data, store the new data in the reserved memory space. And re-reserving a space in the memory, when the new data needs to be updated and deleted, the operation can be directly performed in the memory, simplifying the data processing flow and improving the data processing efficiency. .

Referring to FIG. 1, a hardware architecture diagram of a preferred embodiment of a data storage system of the present invention is shown. The system mainly includes a microprocessor 1, a storage 2 and An input/output device 3, which is connected to the storage 2 and the input/output device 3. The storage 2 includes a memory 21 and a data processing unit 20. The memory 21 is used to store various materials (such as a newsletter or MMS, which may be sourced from other mobile devices or downloaded from the Internet). The memory 21 may be a dynamic random access memory (DRAM) or a synchronous dynamic random access memory (SDRAM). The input/output device 3 includes an LCD liquid crystal display screen and a keyboard for displaying data and inputting information.

The microprocessor 1 is used to call the data processing unit 20 and control the execution of the data processing unit 20. The data processing unit 20 is configured to reserve a space in the memory 21, and when the mobile device receives a new data, store the new data in the reserved memory space, and in the memory 21 Re-reserve a space.

Referring to FIG. 2, a functional block diagram of the data processing unit 20 shown in FIG. The data processing unit 20 includes a memory initialization module 201, a memory reservation module 202, a data storage module 203, and a prompt module 204. The module referred to in the present invention is a computer program segment for performing a specific function, and is more suitable for describing the execution process of the software in the computer than the program. Therefore, the following description of the software is described in the module.

The memory initialization module 201 is configured to initialize the memory 21 when the mobile device is activated.

The memory reservation module 202 is configured to reserve a space in the memory 21.

The data storage module 203 is configured to automatically store the new data into the reserved memory space when receiving a new data.

The memory reservation module 202 is further configured to re-reserve a space in the memory 21 and determine whether the reserved memory space is successful.

The prompting module 204 is configured to prompt the user to release the memory when the reserved memory space fails.

The memory reservation module 202 is further configured to determine whether the user releases the memory successfully. If the user fails to release the memory, it is further determined whether the number of prompts is reached. The failure of the user to release the memory includes: the memory space released by the user is insufficient, resulting in failure of the reserved memory space, or the user refuses to release the memory space, resulting in failure of the reserved memory space.

Referring to FIG. 3, a flow chart of a preferred embodiment of a data storage method of the present invention is shown. In step S401, when the mobile device is activated, the memory initialization module 201 initializes the memory 21.

In step S402, the memory reservation module 202 reserves a space in the memory 21.

In step S403, the mobile device receives a new piece of data.

In step S404, the data storage module 203 automatically stores the new data in the reserved memory space.

In step S405, the memory reservation module 202 re-reserves a space in the memory 21.

In step S406, the memory reservation module 202 determines whether the reserved memory space is successful. If successful, the process ends. If it fails, step S407 is performed.

In step S407, the prompting module 204 prompts the user to release the memory.

In step S408, the memory reservation module 202 determines whether the user releases the memory successfully. If successful, step S405 is performed, and if it fails, step S409 is performed. The failure of the user to release the memory includes: the memory space released by the user is insufficient, resulting in failure of the reserved memory space, or the user refuses to release the memory space, resulting in failure of the reserved memory space.

In step S409, the memory reservation module 202 determines whether the number of prompts has been reached. If the number of prompts has not been reached, step S407 is performed, and if the number of prompts is reached, the flow ends.

The mobile device in the present embodiment may be an electronic device having a data processing function such as a mobile phone, a digital camera, or a PDA (Personal Digital Assistant).

The data storage system and method of the present invention are disclosed above in the preferred embodiments, but are not intended to limit the present invention. Any person skilled in the art will be able to make changes and refinements without departing from the spirit and scope of the invention, and the scope of the invention is defined by the scope of the appended claims.
