QR decomposition (QRD) is a widely used Numerical Linear Algebra (NLA) kernel with applications ranging from SONAR beam forming to wireless MIMO receivers. In this paper, we propose a novel Givens Rotation (GR) based QRD (GR-QRD) where we reduce the computational complexity of GR and exploit higher degree of parallelism. This low complexity Column-wise GR (CGR) can annihilate multiple elements of...
Flexibility in implementation of the underlying field algebra kernels often dictates the life-span of an Elliptic Curve Cryptography solution. The systems/methods designed to realize binary field arithmetic operations can be tuned either for performance or for flexibility. Usually flexibility of these solutions adversely affects their performance. For solutions to reduction operation this adverse...
Flexible constraint length channel decoders are required for software defined radios. This paper presents a novel scalable scheme for realizing flexible constraint length Viterbi decoders on a de Bruijn interconnection network. Architectures for flexible decoders using the flattened butterfly and shuffle-exchange networks are also described. It is shown that these networks provide favourable substrates...
