A novel systolic array is proposed for LS system identification based on QR factorization via Givens rotations. The back-substitution step is circumvented and the structure is fully pipelineable. Thus the method is appropriate for continuous, sample-by-sample mode, adaptive operation. A modification or the above structure is also suggested which is suitable for a wide range of linear algebraic operations and is solely based on Givens rotations.
