Multi-thread data processing method and device, electronic equipment and readable storage medium

Abstract

The invention provides a multi-thread data processing method and device, electronic equipment and a readable storage medium, and the method comprises the steps: firstly determining whether the numberof bytes of to-be-processed data is smaller than or equal to the width of a register or not, and generating an instruction sequence corresponding to a current thread when the number of bytes of the to-be-processed data is smaller than or equal to the width of the register; wherein the instruction sequence comprises to-be-processed data and an atomic operation instruction, and the atomic operationinstruction is used for processing the to-be-processed data; and executing an instruction sequence corresponding to the current thread, the to-be-processed data being data shared by a plurality of threads. According to the embodiment of the invention, when the byte number of the to-be-processed data is smaller than or equal to the width of the register, the to-be-processed data can be written intothe instruction sequence, and the reading or writing operation of the to-be-processed data can be completed through the atomic operation instruction, so that the synchronization of multi-thread datacan be ensured without adopting a thread lock; and the performance overhead of the processor in the multi-thread data synchronization process is reduced.

Description

technical field [0001] The embodiments of the present invention relate to the field of computer technology, and in particular, to a multi-thread data processing method, device, electronic equipment, and readable storage medium. Background technique [0002] As a technology that can realize concurrent execution of multiple threads from software or hardware, multi-threading technology can effectively improve the resource utilization rate of the central processing unit (Central Processing Unit, referred to as CPU) and speed up the program response speed. use. [0003] However, while realizing multi-threaded concurrent execution, it also brings about the problem of data synchronization. For example, when thread A accesses a certain data, thread B also accesses and modifies a constant in the data at the same time, which will cause thread A to finally get a wrong access result. [0004] At present, the way to solve the above problems is usually to use thread locks, that is, duri...

AI Technical Summary

Problems solved by technology

[0004] At present, the way to solve the above problems is usually to use thread locks, that is, during the process of thread A accessing data, other threads cannot access the data, and only after waiting for thread A to release the thread lock, other threads can access the data. Guarantee data synchronization, but using thread locks will bring significant performance overhead to the processor
