Matrix multiply with reduced bandwidth requirements

Systems and methods for reducing the bandwidth needed to read the inputs to a matrix multiply operation may improve system performance. Rather than reading a row of a first input matrix and a column of a second input matrix to produce a column of a product matrix, a column of the first input matrix and a single element of the second input matrix are read to produce a column of partial dot products of the product matrix. Therefore, the number of input matrix elements read to produce each product matrix element is reduced from 2N to N+1, where N is the number of elements in a column of the product matrix.
