Abstract

The invention relates to a data processing method, a processor, a data processing device and a storage medium. The data processing method comprises: reading first sub-data from a first storage deviceaccording to an operation instruction, and storing the currently read first sub-data into a second storage device; obtaining second sub-data, judging whether the currently read first sub-data is greater than or equal to the second sub-data or not; and when the first sub-data is greater than or equal to the second sub-data, resetting the first sub-data, storing the reset first sub-data in the firststorage device as a current comparison result, and then returning to continue to read the first sub-data from the first storage device until related operation corresponding to the operation instruction is completed. Big data is split into small data for cyclic operation processing, and operands are cyclically read according to the data reading capacity, so that the size of data capable of being accommodated during operation processing meets the requirement, and the operation speed is increased.

Description

technical field [0001] The present application relates to the technical field of data processing, and in particular to a data processing method, processor, data processing device and storage medium. Background technique [0002] An atomic operation refers to an operation that will not be interrupted by the thread scheduling mechanism. Once this operation starts, it will run until the end without any thread switching in the middle (for example, the shared variable i performs accumulation, and multiple cores in the case of non-atomic operations At the same time, the result of i++ will be wrong). In a multi-core processor system, multiple processor cores share the same storage space, and the usual data transmission technology may not be able to guarantee atomicity, that is, multiple processor cores may access the same address at the same time. [0003] In the actual program, the operation result is stored in a storage space with a certain address range. Since the storage space...
