A systolic array is used to compute a 248-point complex number-theoretic transform. Next an algorithm is developed to realize a digital filter that uses such transforms and a generalization of the overlap-save method. This solves the conflict between long transform lengths and a wide dynamic range associated with the number-theoretic transform. Finally this algorithm is mapped to a parallel architecture which is simple, regular and expandable, and hence suitable for VLSI implementation. 7 references.
