DenSparSA: A Balanced Systolic Array Approach for Dense and Sparse Matrix Multiplication
DescriptionIn this paper, we introduce DenSparSA, a balanced systolic array centralized architecture that can execute sparse matrix computations with minimal overhead to original dense matrix computations. DenSparSA supports both single-side and dual-side unstructured sparse matrix multiplications with high efficiency. Moreover, the additional hardware required for managing sparsity is compact and decoupled from the conventional systolic array, allowing for minimal power overhead when switched back to dense matrix operations via circuit gating. Compared with existing solutions, DenSparSA delivers competitive (0.82x-1.32x) efficiency in sparse scenarios and 1.17x-2.28x better efficiency for dense scenarios, indicating a better balance between both situations.
