A Parallel Architecture for Digital Filtering Using Fermat Number Transforms
September 1983 (vol. 32 no. 9)
pp. 874-877

In this correspondence, a parallel architecture is developed to compute the linear convolution of two sequences of arbitrary lengths using the Fermat number transform (FNT). In particular, a pipeline structure is designed to compute a 128-point FNT. In this FNT, only additions and bit rotations are required.
Index Terms:
VLSI, Convolution, digital filter, Fermat number transform, overlap-save method, pipeline
