This work presents an FPGA based scalable fixed point QRD architecture based on Givens Rotation algorithm. The proposed QRD core utilizes an efficient pipelined and unfolded 2D MAC based systolic array architecture with dynamic partial reconfiguration (DPR) capability. An improved LUT based Newton-Raphson method is proposed for finding square root and inverse square root which helps in reducing the...
Matrix inversion is an essential step in solving least squares problems and finds application in various communication systems and signal processing applications. A direct matrix inversion involves high computational complexity and hence it is performed using various decomposition techniques like Cholesky decomposition, QR decomposition (QRD), LDL decomposition. In this paper, fixed point architecture...
