Abstract: A technique includes providing a first set of values to a memristor crossbar array and using the memristor crossbar array to perform a Fourier transformation. Using the memristor crossbar array to perform the Fourier transform includes using the array to apply a Discrete Fourier Transform (DFT) to the first set of values to provide a second set of values.

Abstract: Examples herein relate to convolution accelerators. An example convolution accelerator may include a transformation crossbar array programmed to calculate a Fourier Transformation of a first vector with a transformation matrix and a Fourier Transformation of a second vector with the transformation matrix. A circuit of the example convolution accelerator may multiply the Fourier Transformation of the first vector with the Fourier Transformation of the second vector to calculate a product vector. The example convolution accelerator may have an inverse transformation crossbar array programmed to calculate an Inverse Fourier Transformation of the product vector according to an inverse transformation matrix.

Abstract: A method of obtaining a dot product includes applying a programming signal to a number of capacitive memory devices coupled at a number of junctions formed between a number of row lines and a number of column lines. The programming signal defines a number of values within a matrix. The method further includes applying a vector signal. The vector signal defines a number of vector values to be applied to the capacitive memory devices.
