A Parallel VLSI (Very Large Scale Integration) Architecture for a Digital Filter Using a Number Theorectic Transform,

Abstract

The advantages of this architecture for implementing a digital filter using FNT transforms are the following: (1) It requires no multiplication. Only additions and bit rotations are needed. (2) It alleviates the usual dynamic range limitation for long sequence FNT's. (3) It utilizes the FNT and inverse FNT circuits 100% of the time. (4) The lengths of the input data and filter sequences can be arbitrary and different. (5) It is regular, simple, and expandable, and as a consequence suitable for VLSI implementation.
