Solving Eigenvalue and Singular Value Problems on an Undersized Systolic Array
Robert Schreiber · SIAM Journal on Scientific and Statistical Computing · 1986
Systolic architectures due to Brent, Luk and Van Loan are today the most promising method for computing the symmetric eigenvalue and singular value decompositions in real time. These systolic arrays, however, are only able to decompose matrices of a given fixed size. Here we present two modified algorithms and a modified array that do not have this disadvantage. The results of a numerical experiment show that a combination of one of our new algorithms and the modified array can decompose matrices of arbitrary size with little or no loss of efficiency.
