Abstract

The invention relates to a convolution circuit, a processor, a chip, a board card and an electronic device. The convolution circuit comprises a central leaf structure and a plurality of node leaf structures. The central leaf structure is connected with each node leaf structure through an interconnection bus, and the central leaf structure can distribute to-be-processed data to the plurality of node leaf structures through the interconnection bus. Each node leaf structure performs convolution operation on the received input neuron data to obtain a convolution operation result, and sends the convolution operation result to the central leaf structure through the interconnection bus, and by adopting the convolution circuit with the master-slave structure, the problem of a large amount of logiccongestion can be avoided.

Description

technical field [0001] The present application relates to the field of computer technology, in particular to a convolutional circuit, processor, chip, board and electronic equipment. Background technique [0002] With the continuous development of digital electronic technology, various types of artificial intelligence (AI) chips have become the focus of the current technology industry and society. As an important circuit of the computing circuit in the chip, the performance of the convolution circuit (core) is particularly important. [0003] There are a large number of convolution circuits in the current processor to undertake deep learning operations. These convolution circuits are placed together for layout and wiring, which may cause congestion of logic units, resulting in a waste of chip area. Contents of the invention [0004] Based on this, it is necessary to provide a convolutional circuit, a processor, a chip, a board, and an electronic device capable of avoiding...
