Abstract: In some examples, memristive dot product circuit based floating point computations may include ascertaining a matrix and a vector including floating point values, and partitioning the matrix into a plurality of sub-matrices according to a size of a plurality of memristive dot product circuits. For each sub-matrix of the plurality of sub-matrices, the floating point values may be converted to fixed point values. Based on the conversion and selected ones of the plurality of memristive dot product circuits, a dot product operation may be performed with respect to a sub-matrix and the vector. Each ones of the plurality of memristive dot product circuits may include rows including word line voltages corresponding to the floating point values of the vector, conductances corresponding to the floating point values of an associated sub-matrix, and columns that include bitline currents corresponding to dot products of the voltages and conductances.
