G. M. Megson *

Computing Laboratory, University of Newcastle-Upon-Tyne, Claremont Tower, Claremont Road, Newcastle-Upon-Tyne NE1 7RU, UK

An improved two layer systolic algorithm for computing the product of two n x n band matrices A and B with bandwidths w1 and w2 respectively is described. The array requires

, and efficiency e = 1 and computation time

[equation: see PDF]

inner product steps and requires only a single pass of data through the design.
