State-space approach to implementation of FIR systems using pipeline rotation structures
Robert T. Wirski, Krzysztof W. Wawryn, Bogdan Strzeszewski · 2012
In the paper, a novel implementation technique of orthogonal FIR systems is proposed. Starting from a state-space model of such a system, presented algorithm computes a fully pipeline structure consisting of Givens Rotations. This technique is illustrated by an FPGA hardware design example of a low-pass FIR filter.
