ABSTRACT:
The specification discloses an apparatus and method for processing an image as part of a fast Fourier transform (FFT) operation. An image processor includes a first and second memory, each for storing the data representing an image as an array of numbers in a format having rows and columns of data positions. A controller is provided for scrolling the data in each row of the second memory with respect to the first memory by at least one data position and for outputting the data of both memories to a data processor. The data processor combines every other group of at least one number of each row of the scrolled data with a corresponding every other group of at least one number of each row of the data from the first memory and passes to its output the data from the first memory for the remaining data positions, whereby a new array of data is produced that is useful as part of a fast Fourier transform operation.
