Abstract
A system performs matrix multiplication of a vector by a two-dimensional matrix by evaluating whether the vector includes zero values. Rows of the matrix are loaded into a first memory device from a second device. Rows corresponding to the indexes of the zero values are not loaded. A dot product of columns of the matrix and the input vector is performed and stored. The matrix may be stored in the second memory device such that only entries for non-zero entries are stored. The rows of the matrix may be reconstructed in the first memory device from these entries.
