Problems solved by technology

[0004] For the current data processing method, according to the current computer system structure standards, the driver set at the kernel layer should process data in the kernel mode, and the system authority under the kernel mode is the highest, that is, in the kernel mode, the system can be The memory and the address space of the operating system are accessed arbitrarily, so once an error occurs in the data processing process, it will directly lead to a system crash, resulting in system restart and data loss.
[0005] Moreover, due to the limited resources of the kernel layer, insufficient resources often occur during data processing
For example, the memory resources of the kernel layer often cannot meet the needs of image data processing, and the image data processing efficiency is low.
[0006] In addition, the current method of data processing, because the kernel layer can only process data with standard data formats, it does not support data processing of non-standard data formats generated through special processing, for example, does not support the processing of self-generated data generated through special encoding. Define the processing of format data, data processing is not flexible
[0007] It can be seen that the current method of data processing is limited by the resources of the kernel layer and system permissions, and the stability of data processing is poor, the efficiency is low and inflexible, and the above three points are important factors affecting the performance of data processing. Therefore, the current The method of data processing has the problem of low data processing performance

Abstract

The invention discloses a data processing device, which comprises an application layer module on an application layer and a driver in a core layer, wherein the driver collects data to be sent to the application layer module, the application layer module processes the data of the driver. The invention also discloses a data processing method, comprising that the core layer collects data to be sent to the application layer, the application layer processes the data. The invention can improve data processing ability.

Description

technical field [0001] The invention relates to the field of computers, in particular to a data processing method and device. Background technique [0002] After the computer collects peripheral device data, it usually needs to go through a certain data processing process before it can be output to the user. For example, the computer collects the image data of the video camera, and the collected data can only be presented to the user after decoding, zooming, special effects and other processing. [0003] At present, when processing data, its software structure often adopts a two-tier architecture, from bottom to top is the kernel layer and the application layer, in which the kernel layer collects data from computer peripheral equipment and processes the data, and the application layer communicates with The interface of the kernel layer obtains the data processed by the kernel layer. The specific steps include: setting the driver at the kernel layer to collect device data, ...
