Comments on "A systolic array for computing BA/sup -1/
Jaime H. Moreno, Thomas A. Lang · IEEE Transactions on Acoustics Speech and Signal Processing · 1989
An algorithm and a systolic array for computing BA/sup -1/ was presented by P. Comon and Y. Robert (see ibid., vol.ASSP-35, p.717-23, June 1987). A and B are n by n and p by n matrices, respectively. Such an array computes BA/sup -1/ in (4n+p-2) time units using n(n+1) processing elements (PE's). The commenters apply a graph-based method for the design of systolic arrays to such an algorithm. They systematically derive the original array and another array that performs the computation in the same time but using (n(n+1)/2+pn) units. For p>
