QR decomposition using FPGAs

2016 IEEE National Aerospace and Electronics Conference (NAECON) and Ohio Innovation Summit (OIS), 2016
This paper describes the architecture and implementation of a high performance QR decomposition IEEE754 single precision floating point core, using a modified Gram-Schmidt algorithm. Using Intel's new floating point Arria 10 FPGAs, synthesis is used to generate column high functional units, giving O(n2) processing times.

New Parameter-Identification Method Based on QR Decomposition for Nonlinear Time-Varying Systems

Journal of engineering mechanics, 2019
A new identification method based on QR decomposition for nonlinear time-varying systems is proposed in this paper, which is applied in a time-varying multiple-degree-of-freedom (MDOF) dyna...

Generalizations of the singular value and QR decompositions

Signal Processing, 1991
The author provides a state-of-the-art survey of a recently discovered set of generalizations of the ordinary singular value decomposition, which contains all existing generalizations for two and three matrices as special cases. He presents the main theorem and discusses structural properties of these generalized singular value decompositions.

Privacy-Preserving Outsourcing Computation of QR Decomposition in the Encrypted Domain

2019 18th IEEE International Conference On Trust, Security And Privacy In Computing And Communications/13th IEEE International Conference On Big Data Science And Engineering (TrustCom/BigDataSE), 2019
Signal processing in encrypted domain has become an important mean to protect privacy in an untrusted network environment. Due to the limitations of the underlying encryption methods, many useful algorithms that are sophisticated are not well implemented.

Implementation of Givens QR-Decomposition in FPGA

2002
A new parallel processor structure for Givens QR-decomposition intended for the FPGA implementation is presented. The structure is derivedusing methodof mapping regular algorithms using affine transformations of the algorithm graph. The methodsupp orts pipelined processor unit design, and provides efficient hardware utilization.

On the Structure of Generalized Singular Value and QR Decompositions

SIAM Journal on Matrix Analysis and Applications, 1994
The author has previously generalized both singular value decomposition and \(QR\) decomposition from a single matrix to a chain of matrices. Here he obtains formulas for the sizes of the blocks which occur.
