Abstract

The invention provides a system for executing atomic operation, an atomic operation method and device. The atomic operation method comprises the steps of receiving a first atomic operation instruction sent by a computing unit, storing a data write-in address in the first atomic operation instruction in a write-in address record table, and determining that the execution of the first atomic operation instruction is finished, and updating the table item valid information of the write address table item corresponding to the first atomic operation instruction in the write address record table into an invalid state.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a system for performing atomic operations, an atomic operation method, and a device. Background technique [0002] An atomic operation usually means that when multiple threads access shared resources, once the operation of a certain thread starts, it will run until the end without being interrupted by other threads. Such an operation is called an atomic operation. [0003] In related technologies, in order to ensure the atomicity of atomic operations, atomic operations are often executed serially through the bus, and it is strictly guaranteed that the last atomic operation instruction is completely executed before the next atomic operation instruction can be received through the bus And execute, this will lead to a long overall execution time and low efficiency. Contents of the invention [0004] Embodiments of the present disclosure at least provide a system f...
