Abstract

In this paper, we present a parallel VLSI architecture that is matched to a class of direction (frequency, pole) finding algorithms of type ESPRIT. The problem is modeled in such a way that it allows an easy to partition full parallel VLSI implementation, using unitary transformations only. The hard problem, the generalized Schur decomposition of a matrix pencil, is tackled using a modified Stewart Jacobi approach that improves convergence and simplifies parameter computations. The proposed architecture is a fixed size, 2-layer Jacobi iteration array that is matched to all sub-problems of the main problem: 2 QR-factorizations, 2 SVD's and a single GSD-problem. The arithmetic used is (pipelined) Cordic.
