The present application relates to a data processing method, a processor, a data processing device and a storage medium. The data processing method includes: reading the first sub-data from the first storage device according to the operation instruction, storing the currently read first sub-data in the second storage device, obtaining the second sub-data, and storing the currently read first sub-data in the second storage device. The obtained first sub-data and the second sub-data are added to obtain the current operation result, and the current operation result is stored in the first storage device, and then returns to continue reading the first sub-data from the first storage device until the operation is completed. The relevant operation operation corresponding to the instruction. By dividing the big data into small data for cyclic operation processing, and by cyclically reading the operands according to the data read capacity, the size of the data that can be accommodated in the operation processing can meet the requirements, and the operation speed is accelerated.
Description
technical field [0001] The present application relates to the technical field of data processing, and in particular, to a data processing method, a processor, a data processing device and a storage medium. Background technique [0002] 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 (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 guarantee atomicity, that is, multiple processor cores may access the same address at the same time. [0003] In an actual program, the operation result is stored in a storage space with a certain address range. Since the storage space may be accessed by ...
