Abstract

The embodiment of the invention discloses a data processing method and device, a neural network accelerator and a storage medium. The data processing device comprises a neural network processing module, a memory allocation module and a storage module connected with the neural network processing module and the memory allocation module. The neural network processing module is used for executing each calculation layer in a preset neural network and transmitting a calculation result corresponding to each calculation layer to the storage module; the memory allocation module is used for continuously acquiring the idle physical addresses in the storage module, generating address mapping information between the idle physical addresses and the virtual addresses, and sequentially allocating corresponding virtual address spaces for each calculation layer in the preset neural network; and the storage module is used for storing a calculation result corresponding to each calculation layer in the preset neural network to a corresponding physical address based on the virtual address of the virtual address space and the address mapping information.

Description

technical field [0001] The embodiments of the present application relate to the technical field of data caching, and in particular, to a data processing method, device, neural network accelerator, and storage medium. Background technique [0002] Artificial intelligence algorithms are relatively complex. Usually, a scene requires multiple algorithms to be superimposed to complete, and an algorithm is usually implemented by a multi-level computing layer. The computing layer can be divided into tensor class and vector class. [0003] In a general-purpose neural network accelerator, different types of computing layers are assigned to different computing engines for calculation. For each computing layer, it needs to input feature image data and weight data, and send them back to the storage space after the calculation is completed. Storage, so for each computing layer, a physical address needs to be allocated in the storage space for data buffering. [0004] At present, the mic...
