Title:
SPARSE MATRIX STORAGE AND COMPUTATION SYSTEM AND METHOD
Document Type and Number:
WIPO Patent Application WO/2023/272917
Kind Code:
A1
Abstract:
A sparse matrix storage and computation system and method, which belong to the field of microelectronic devices. The system comprises: a first storage array, which is used for storing a coordinate index table of non-zero elements of a sparse matrix; a second storage array, which is used for storing elements of the sparse matrix, and also serves as an in-situ computing core for a multiplication operation of the sparse matrix; a partitioning and storage scheduling unit, which is used for partitioning the sparse matrix into several sub-matrices, storing the sub-matrices in the second storage array according to different compression formats, and establishing an index table corresponding to the sparse matrix; and a second peripheral circuit, which is used for converting a vector into a voltage signal, applying the voltage signal to a bit line or a word line corresponding to each sub-matrix of the sparse matrix, and completing a multiplication operation of the sparse matrix and the vector.
