Abstract

This paper proposes a high-speed and low latency QR decomposition (QRD) architecture. In the proposed QRD architecture, two QRD algorihms, the CORDIC-based algorithm and Gram-Schmidt, is effectively combined together to reduce hardware latency. The experimental results show that the proposed architecture implemented with Samsung 0.13 um technology achieves 16.7 % speed-up over the conventional Givens rotation-based architecture with only 5.9% area overhead for 4 × 4 matrix decomposition.
