Disk-based data writing method, data writing device and terminal equipment

Abstract

The invention provides a disk-based data writing method, a disk-based data writing device and terminal equipment, and the method comprises the steps: writing to-be-written data of a to-be-written diskinto a first memory block in a memory area of the terminal equipment when the to-be-written data of the to-be-written disk is obtained; judging whether the first memory block is fully written with data to be written into the disk or not; if it is confirmed that the first memory block is not fully written with the data to be written into the disk, writing the obtained data to be written into the disk into the remaining storage space of the first memory block again, and then returning to execute and judge whether the first memory block is fully written with the data to be written into the diskor not; and if it is determined that the first memory block is filled with the data to be written into the disk, writing the data to be written into the disk stored in the first memory block into thedisk by adopting a direct IO access method. The technical problem that a traditional disk writing mode easily causes system jamming can be solved to a certain extent.

Description

technical field [0001] The present application belongs to the technical field of data storage, and in particular relates to a disk-based data writing method, a data writing device, a terminal device, and a computer-readable storage medium. Background technique [0002] At present, the traditional way of writing data to the disk is: the operating system of the terminal device first copies the data stored in the memory to be written to the disk to the page cache of the file system, and then the operating system writes the data in the page cache to disk. [0003] When the data to be written to the disk is stream data collected in real time (such as image data continuously collected by a camera), the operating system of the terminal device needs to continuously copy the stream data collected in real time from the memory to the page cache of the file system, which will As a result, the memory consumption and CPU usage of the terminal device are very high, so that the terminal de...
