Problems solved by technology

However, since multiple processors read data very frequently, using the same physical memory requires a very large bandwidth of the heap memory, and when the bandwidth requirements of each processor accessing the heap memory exceeds the actual bandwidth of the physical memory, it will cause Slower processing

Abstract

The invention relates to a data processing method and device, and a related product, and the device comprises one or more data processing devices which are used for obtaining a neural network model and control information from other processing devices, executing specified machine learning operation, and transmitting an execution result to other processing devices through an I / O interface; when themachine learning arithmetic device comprises a plurality of data processing devices, the plurality of data processing devices can be connected through a specific structure and transmit data. The plurality of data processing devices are interconnected and transmit data through a PCIE (Peripheral Component Interconnect Express) bus; wherein the plurality of data processing devices share the same control system or have respective control systems, share a memory or have respective memories; the interconnection mode of the plurality of data processing devices is any interconnection topology. According to the data processing method and device, and the related product provided by the embodiments of the invention, the bandwidth of the heap memory is saved, and the operation processing speed can be improved.

Description

technical field [0001] The present disclosure relates to the field of computers, in particular to a data processing method, device and related products. Background technique [0002] In the related art, in order to improve the processing speed, multiple processors are used to perform the calculation and processing of the neural network model. In the process of using multiple processors to process the neural network model, multiple processors need to access the same heap of memory to perform read and write operations on required data during execution. However, since multiple processors read data very frequently, using the same physical memory requires a very large bandwidth of the heap memory, and when the bandwidth requirements of each processor accessing the heap memory exceeds the actual bandwidth of the physical memory, it will cause Processing speed is reduced. Contents of the invention [0003] In view of this, the present disclosure proposes a data processing metho...
