Abstract
A matrix operation device performs matrix multiplication of an input electrical signal by utilizing a plurality of charge-coupled devices having split electrodes. The multiplication is carried out by the split electrodes of the charge-coupled devices. A signal to be transformed is sampled by a delay circuit in the input of the operation device. The sampled signal is supplied to the operation device in the form of a time series or sequence consisting of the sample signals. Each sample is multiplied by a corresponding coefficient. The split electrodes of the charge-coupled devices have weighting coefficients corresponding to coefficients in the matrix. The samples multiplied by the coefficients are added in the output of the operation device and provided as an output signal, corresponding to the development of the matrix multiplication.
