  • Abstract
    Reconstruction of computer tomography images requires several processing steps for reduction of electronic noise and correction of physical inaccuracies. The most time-consuming step is a convolution implemented with fast Fourier transforms. The architecture of a single board computer designed to provide an efficient implementation of the fast Fourier transform is presented. Parallel and pipeline features are discussed and a typical array routine is used to present software features
