Problems solved by technology

However, since the single-core neural network processor needs to be compatible with most neural network models, it needs to provide support for the existing different types of neural networks and neural network operations of different scales, which makes the structure of the existing single-core neural network processor complex. , expensive, and for small-scale, simple-structured neural network operations and operations of simple neural network models such as spiking neural networks (SNN), there are also problems of wasting hardware resources and excessive power consumption. At the same time, a single The core neural network processor does not accelerate the parallelism between different layers in the neural network operation process, and there is still a lot of room for optimization

Abstract

The present disclosure provides a network processor and a network operation method. A memory and a cache are used to perform network operations. The memory is used to store data and instructions of the network operation. The cache is connected to the memory through a memory bus, which can make full use of the actual operation of the hardware. capacity, reduce costs, reduce power consumption overhead, and make full use of the parallelism of the network to improve the efficiency of network operations.

Description

technical field [0001] The present disclosure relates to the technical field of artificial neural networks, and more particularly, to a network processor and a network computing method. Background technique [0002] Artificial neural network (ANN) abstracts the human brain neuron network from the perspective of information processing, establishes a simple model, and forms different networks according to different connection methods. At present, artificial neural networks have made great progress in many fields, and are widely used to solve practical problems in the fields of pattern recognition, intelligent robots, automatic control, prediction and estimation, biology, medicine, and economics. [0003] As a new type of special-purpose processor, the single-core neural network processor uses special instructions to make full use of the parallelism of neural network operations to perform neural network operations. However, since the single-core neural network processor needs ...
