Data copy processing method, device, electronic device and storage medium

Abstract

The data copy processing method, device, electronic equipment and storage medium provided by the present disclosure are applied to the RISC reduced instruction set architecture, by determining the data copy request message; according to the data copy request message, it is determined whether the source data address and the target data address are All are 16-byte aligned; when the source data address and the target data address are 16-byte aligned, the first memory access instruction group is used, and the byte to be copied is copied from the source data address to the target data address with 128 bits. And obtain the remaining bytes in the bytes to be copied; copy the remaining bytes from the source data address to the target data address by using a byte-by-byte copy method or using the second memory access instruction group based on 64-bit copy processing deal with. Compared with the prior art, by first aligning the addresses, and then directly copying the bytes to be copied by using the first memory access instruction group, the processing efficiency and running speed of the copied data are effectively improved.

Description

technical field [0001] The present disclosure relates to computer technology, and in particular to a data copy processing method, device, electronic equipment and storage medium. Background technique [0002] Copying data using the copy function is an indispensable step in the process of processing data by a computer. [0003] In the prior art, the computer uses some function instructions to copy data, for example, the memory copy function memcpy. Specifically, the memcpy function can be used to copy n bytes to be copied from the source data address to the target data address. When using the memcpy function to copy data, when the target data address has stored several bytes, after executing the memory copy function, these stored bytes will be overwritten; in addition, when the target data address and source data When there is address overlap between addresses, after executing the memory copy function, some bytes in the bytes to be copied stored in the overlapping address i...

AI Technical Summary

Problems solved by technology

[0004] However, as the amount of copied data increases, the copying efficiency of data copying using the memcpy function cannot meet the growing demand of the data amount, which is not conducive to the computer's data and operations on large data
