Embedded-type device for smoothly storing data to universal file system and method for smoothly storing data to universal file system

Abstract

The invention provides a method for smoothly storing data to a universal file system, which comprises the following steps that: 1) stream media data is started to record; 2) data collection is executed by a stream media source; 3) the collected data file is written into physical device data through the transmission of application programming interface (API); 4) data is copied to a file system buffer area; 5) a file system is uploaded, and management information is buffered; 6) whether the stream media service is ended is judged. Due to the adoption of the embedded-type device and the method for smoothly storing data to the universal file system, a device with slow storage sped can be used for normally storing stream media data without noise.

Description

technical field [0001] The invention relates to a storage method, in particular to an embedded device and method that supports smooth storage of data streams to a common file system on a low-speed storage device. Background technique [0002] The computing power of embedded devices is getting stronger and stronger. Many embedded devices have multimedia cameras (video shooting, photo continuous shooting or audio recording functions), and the real-time data obtained through the cameras are stored in the file system as ordinary files. Embedded devices usually support common file system formats (such as FAT12, FAT16, FAT32, NTFS, ExFAT, Ext2, Ext3, HFS, HFS+, etc.). The support of the general file system means that the files stored in the medium can be shared with other systems that support these file system formats without any format conversion. Therefore, when storing files and writing data, the storage devices must be accessed according to the format of the relevant file sys...

Problems solved by technology

However, devices with different architectures and slow writing speeds need to design special file systems separately, which requires a huge workload. Moreover, with the emergence of devices with slow writing speeds in new architectures, it is necessary to passively write features for the devices and then rewrite them. Design a special file system and modify a lot of codes; in addition, the special file system saves only files, and another disadvantage is that it does not follow the storage rules of the general file system, the saved files (such as slow architecture cards), and the stored files It cannot be used directly with other devices that support common file systems

Adding the action of file conversion not only wastes a lot of time for users to wait for the conversion of data from special file system files to standard file system file formats, but also makes it inconvenient for users to use
