Abstract

The invention discloses a matrix multiplication circuit, a method for executing sparse matrix multiplication by using the matrix multiplication circuit and a related product. The matrix multiplication circuit may be implemented as a computing device included in a combinatorial processing device, which may also include an interface device and other processing devices. The computing device interacts with other processing devices to jointly complete computing operation specified by a user. The combined processing device can further comprise a storage device, and the storage device is connected with the computing device and the other processing devices and used for storing data of the computing device and the other processing devices. The scheme of the disclosure provides a circuit supporting sparse matrix multiplication, which can simplify processing and improve processing efficiency of a machine.

Description

technical field [0001] This disclosure relates generally to the field of data processing. More particularly, the present disclosure relates to matrix multiplication circuits, methods, chips and boards for performing sparse matrix multiplication using matrix multiplication circuits. Background technique [0002] Sparse matrices occupy a certain proportion in data processing. For example, the deep learning algorithm that has developed rapidly in recent years is a computationally and storage-intensive tool. With the increasing complexity of information processing tasks, the real-time and accuracy requirements of the algorithm are constantly increasing. Neural networks are often designed to Increasingly deeper and deeper, it requires more and more computing and storage space, which makes it difficult for the existing deep learning-based artificial intelligence technology to be directly applied to mobile phones, satellites or embedded devices with limited hardware resources. ...
