when the target file needs to be copied from the self-adaptive mobile memory to the target system:
firstly, the self-adaptive mobile memory is accessed to a target system through a USB interface 300, and a target file format is input through an others key 200:
on one hand, after the USB interface 300 is accessed to the target system, the register control unit 500 automatically detects the file system of the target system accessed to the USB interface 300 to obtain the target file system format, and correspondingly outputs a preset first register value corresponding to the target file system format to the file system reading logic search unit 600 according to the target file system format; after receiving the first register value output by the register control unit 500, the file system read logic lookup unit 600 looks up the file system read logic table according to the received first register value to obtain a target file system read data address corresponding to the target file system format, and sends the target file system read data address to the FIFO read-write control unit 800;

Optionally, the adaptive mobile memory further comprises a display screen 400 and a display screen control module 900, wherein the display screen 400 is connected to the register control unit 500 through the display screen control module 900. The register control unit 500 is used for displaying the current selection status of the adaptive mobile memory, including the current target file system format, the target file type and the target file format, on the display screen 400 through the display screen control module 900. Specifically, the display control module 900 displays the current selection status of the adaptive mobile storage device on the display 400 according to the control signal transmitted by the register control unit 500. The current target file system format, the target file type and the target file format are displayed through the display screen 400, so that the user can conveniently adjust the input error in time, for example, the USB interface 300 is disconnected from the target system and then is accessed again. The Display screen 400 in this embodiment is an LCD (short for Liquid Crystal Display).
Optionally, the files to be converted are input by using the others key 200, and the specific implementation method includes:
step Q1, inputting the file type to be converted through the others key 200, and recording the file type as a target file type;
step Q2, after inputting the target file type, inputting the file format to be converted under the current target file type again through the others key 200, wherein the file format is the target file format.
It can be seen that in this embodiment, before the target file format is input by using the others key 200, the target file type to be converted may be input by using the others key 200, which increases the flexibility of use to some extent and also increases the user experience.
In order to further increase the user experience and the flexibility of the use of the present invention, the present invention presets the number of times that the different files 200 of the types supported by the present invention are continuously pressed. Thus, for step Q1 above, the register control unit 500 is further configured to:
receiving and counting the continuous pressing times of the others key 200, and recording the times as N times; wherein N is greater than or equal to 1 and less than or equal to a preset maximum threshold value of the continuous pressing times;
find out the preset files type corresponding to N times of continuous pressing of the keys 200, the file type is the target file type.
Similarly, the present invention presets the number of times that the file formats supported by the present invention are pressed respectively corresponding to the others keys 200 after the target file type is input in the register control unit 500. Thus, for step Q2 above, the register control unit 500 is further configured to:
recording the number of times that the others key 200 is pressed after the target file type is input, and recording as M times; wherein M is greater than or equal to zero and less than or equal to a preset first threshold;
when M is not equal to 0, finding out a corresponding file format which is pressed for the Mth time after a preset others key 200 inputs a target file type, wherein the file format is the target file format;
and when M =0, finding out a default file format which is preset and corresponds to the current target file type, wherein the default file format is the target file format.
For example, it may be preset in the register control unit 500 that: pressing the others key 200 once in succession represents the file type "pictures", pressing the others key 200 twice in succession represents the file type "audio", and pressing the others key 200 three times in succession represents the file type "video"; taking "picture" as an example, it can be preset in the register control unit 500: after entering the target file type "Picture": pressing the others key 200 a first time represents jpeg format, pressing the others key 200 a second time represents bmp format, and pressing the others key 200 a third time represents png format. When the user presses the others key 200 once, the register control unit 500 finds out the target file type "pictures" and correspondingly displays the "Images" on the display screen 400; after the "Images" is displayed on the display 400, the user presses the others key 200 three times and then stops pressing, the register control unit 500 finds out the PNG format represented by the third pressing of the others key 200 as the target file format, and correspondingly displays the "PNG" on the display 400, as shown in fig. 3. In addition, in fig. 3, "exFAT" displayed on the display screen 400 is the currently selected target file system format on the adaptive mobile storage according to the present invention.
When the file type is "audio", "video", reference is made to the above.
In this embodiment, the memory is a DDR memory (collectively referred to as DDR SDRAM (Double Data Rate SDRAM)).
To increase the convenience of implementation, the adaptive mobile memory in this embodiment is implemented based on an FPGA (Field programmable Gate Array).
Example 2:
fig. 4-6 show another embodiment of the adaptive mobile memory according to the present invention.
As shown in fig. 4-6, the difference between this embodiment and embodiment 1 is that the adaptive mobile memory in this embodiment further includes a file system format input key for manually inputting a file system format to be converted, and the file system format input key is connected to the register control unit 500.
Optionally, the file system format input key includes at least one of an exFAT key 1 for inputting an exFAT format (extended FAT file system format), a FAT32 key 2 for inputting a FAT32 format (file system format stored in a 32-bit binary format), and an NTFS key 3 for inputting an NTFS format (journaling file system format). As shown in fig. 3, the file system format input key in this embodiment includes all of the exFAT key, the FAT32 key, and the NTFS key described above. The exFAT key 1, the FAT32 key 2 and the NTFS key 3 are all arranged on the casing 100 in a row and are distributed at intervals.
When in use, after the USB interface 300 is connected to the target system, the user may select the corresponding file system format input key to input the target file system format according to the actual requirement, for example, the target file system format "exFAT" may be input to the register control unit 500 through the exFAT key, the target file system format "FAT 32" may be input to the register control unit 500 through the FAT32 key, and the target file system format "NTFS" may be input to the register control unit 500 through the NTFS key.
The use of the file system format input keys increases the flexibility of use of the invention and also increases the user experience.
When the user inputs the target file system format using the file system format input key, the register control unit 500 does not automatically detect the file system of the target system accessed on the USB interface 300.
The same and similar parts in the various embodiments in this specification may be referred to each other.
Although the present invention has been described in detail in connection with the preferred embodiments with reference to the accompanying drawings, the present invention is not limited thereto.
