The Pipelined QR Decomposition Hardware Architecture Based On Givens Rotation CORDIC Algorithm

Abstract

QR decomposition plays a huge role in the adaptive filtering, control systems and a computation modeling of the physical processes. This paper concerns the issue of a QR decomposition hardware implementation features based on Givens rotation technique. For speed-up of the computation purposes used a pipelined architecture and CORDIC algorithm. The hardware costs and speed of a computation is evaluated for a different adders architectures in the CORDIC algorithm. The Givens rotation technique is used because it have a simple architecture and optimized hardware implementation.
