Abstract

The invention provides a data processing method and a data processing device, which are used for solving the problems of low data transmission efficiency and high storage space cost in the prior art.The method comprises the steps of obtaining a first data set from a disk to a main memory; controlling the CPU to decompress the first data set for the first time according to a first decompression algorithm, and determining a second data set decompressed for the first time, the first decompression algorithm being a decompression algorithm corresponding to a compression method which does not support random access; obtaining a video memory of the second data set to an image processor GPU from a main memory; and controlling at least one processing core of the GPU to decompress the second data set for the second time according to a second decompression algorithm which is a random access decompression algorithm.

Description

technical field [0001] The present invention relates to the field of computer technology, in particular to a data processing method and device. Background technique [0002] A graphics processing unit (Graphics Processing Unit, GPU) is a kind of hardware included in a computer. The GPU can use many internal processing cores to assist the computer's central processing unit (Central Processing Unit, CPU) to accelerate various types of computing tasks in parallel. figure 1 It is a schematic diagram of the computing and storage framework of a computer including a GPU. Specifically, when the GPU needs to be used to process data, the processed data first needs to be imported from the computer's disk into the main memory, and then transferred from the main memory to the GPU's video memory , and then the processing core in the GPU obtains the processed data from the video memory for processing. In the above process, when the data volume of the processed data is large, the transmiss...
