AI Technical Summary

Problems solved by technology

Due to the limitation of I / O bandwidth, at least two I / O read and write operations are involved in one calculation process. Frequent I / O read and write operations take a long time, resulting in low processing efficiency of the processor.

Abstract

The invention relates to a data preprocessing method and device, computer equipment and a storage medium. By storing target output data corresponding to target operation on a main memory, reading frequency of the target output data is reduced, and the occupation time of I / O reading operation in the operation process can be reduced, so that the speed and the efficiency of the processor can be improved.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a data preprocessing method, device, computer equipment and storage medium. Background technique [0002] With the explosive growth of data volume, artificial intelligence algorithms such as machine learning have been applied more and more. Machines learn by analyzing a large amount of data. Therefore, big data operations such as machine learning have a sharp increase in memory access requirements. [0003] In order to meet the requirements such as memory access capacity of the memory, a multi-level memory architecture is usually adopted at present, that is, an architecture using a cache memory, a main memory, and an external memory. Among them, the access speeds of the cache memory (Cache), the main memory and the external memory decrease sequentially, and the storage capacities increase sequentially. However, since the bandwidth of I / O in computer equipment is oft...
