A VLSI architecture for the real time computation of discrete trigonometric transforms

Abstract

The Discrete Trigonometric Transforms are defined as a class of transforms. An algorithm for calculating the Discrete Fourier Transform is extended to cover all members of the defined class. A VLSI architecture which provides for real time calculation of these transforms is presented. This architecture provides simple interconnections, identical processing elements and minimal control complexity. © 1993 Kluwer Academic Publishers.
